LightMachinery excimer lasers are powerful and reliable sources for ultraviolet light. They now feature exciPure™ technology, introduced in 2016; exciPure represents the greatest improvement in excimer gas lifetime and reduction in operating costs in a generation.

CNI offers various ultraviolet lasers (diode lasers and diode-pumped solid-state lasers) with many wavelengths between 213 nm and 349 nm. The output power is up to 3 W, and the pulse energy is up to 10 mJ. The laser products include 5 series: high energy, high power, high stability, low noise and single longitudinal mode laser.

Shallow depth of field is the term used to describe an image that has a shorter field distance. Therefore the region of acceptable sharpness is smaller, and has a higher drop-off rate.

Now that we have a general understanding of depth of field and the various types of a camera focus involved, let's talk specifics. How does depth of field actually work? Here's a quick graphic to get us started.

Depth lives along the z-axis, and this is commonly referred to as z-space. So the depth of your phone when held vertically, based on the figures above, would be…

Ultraviolet lasers encompass a variety of types, including laser diodes, solid-state bulk lasers, fiber lasers, dye lasers, excimer lasers, argon ion lasers, and nitrogen lasers. Additionally, there are laser sources that achieve ultraviolet emission through nonlinear frequency conversion processes such as frequency doubling, tripling, or quadrupling.

If you’re a director, you always want to understand as much as possible with regard to creative decisions, including depth of field.

What are UVlasersused for

Sacher Lasertechnik has developed a frequency-doubled laser system where a resonant cavity including a frequency doubler crystal is pumped via a tunable diode laser. Depending on the required SHG power, the tunable diode laser is either a high power external cavity laser, or a two stage Master Oscillator Power Amplifier System. The covered wavelength regime ranges from 365 nm up to 540 nm.

Large depth of field is the term used to describe an image that has a deeper field, therefore the region of acceptable sharpness has a lower drop-off rate. This can be used to capture a larger area of acceptably sharp images.

For higher peak powers, we offer the 266 nm PNU-M01210-1x0 lasers, part of the Powerchip series, also available with various wavelengths including 355 nm, 266 nm and 213 nm. Peak powers of tens of kilowatts (or even 160 kW at 1064 nm) are generated, while the pulse durations are always well below a nanosecond. These lasers use a specific long life process to extend lifetime between refurbishments.

with pulse durations from picoseconds (PICOPOWER series) to sub-nanoseconds and nanosecond (PULSELAS-A/P series). While the passively Q-switched sub-nanosecond microchip UV lasers are the best alternative for low-cost and maintenance-free operation, the harmonically tripled and quadrupled regeneratively amplified picosecond lasers offer very high peak powers for material processing and nonlinear optical applications.

Camera distance can also be referred to as focus distance, because as you move your camera, you are forced to change the position of the focal element within the body of the lens to keep your subject in focus.

Combine the forces that govern depth of field to achieve some really spectacular results. If you’re a cinematographer, you need to understand each of these forces more than anyone on set.

Selective focus is a technique where a photographer or filmmaker uses an extremely shallow depth of field to isolate a subject.

Ready to capture some seriously cinematic images? Check out this article on How to Make a Shot List Using StudioBinder Software. We show you how to add custom description (like depth of field) to each shot so that you can be as precise with your shots as possible. Take the skills you learned in this article and create something spectacular. Have questions or comments? Have a link that shows off your DOF skills?

Testing the circle of confusion is a very useful method for lens and camera manufacturers to test focus, because it helps determine when as subject is officially out of focus.

This can also be referred to as a deep depth of field, and some cinematographers will simply use the term “depth” to describe shots with a large DOF. It can also be referred to as deep focus.

Anyone, not only suppliers themselves, can report additional suppliers. If possible, please provide a web address showing that this supplier indeed offers such products.

There are various ways to control you depth of field. Each method has a profound impact on the area of acceptable focus, but combining multiple methods will allow incredible control over your images.

This squishes the angle to make it thinner, which spreads your field further apart, and thus creates a larger depth of field.

When you increase the diameter of your aperture, you physically change the angle at which light rays may enter the lens.

You aren’t actually changing the depth of field by putting a longer lens on your camera, but rather moving your camera closer (without having to get any closer).

When you decrease the diameter of your aperture, you physically change the angle at which light rays may enter the lens.

That doesn't mean you should buy a camera because it has a smaller sensor, but it is something to keep in mind with regard to governance.

A shallow depth of field may help with the emotional tone of your image, but it will rarely take you as far as most cinematographers need.

Sacher Lasertechnik also offers the Jaguar UV laser, a MOPA system with fourth harmonic generation for output wavelengths from 205 nm to 270 nm.

They weren't changing lenses or settings, but they used their actors and blocking to create a shot with different layers of depth of field, and achieved a really amazing shot that both isolated information, but also stayed in focus.

An already registered supplier can use a customized form to report the full list of offered photonics products. That form is reachable with a link at the bottom of the supplier's profile page.

Some of the most beautiful shots have used a shallow depth of field, as well as some of the most disturbing shots (still beautiful in their own way).

The center most point of the field is known as the point of focus. The imaginary two dimensional plane that extends from that point is known as the plane of focus.

Objects that falls in between those doors would be acceptably sharp, and any objects that falls outside of those doors would not.

The larger your camera sensor, the more your depth of field decreases. This is because you are forced to move closer to your subject to fill your frame. You can manipulate your DOF through aperture, and focus distance.

If you're going to be filming a long take in your next project, you may want to keep your depth of field as large as you can. Based on the knowledge you just picked up, you may have already determined how you would film a long take.

The IPEX-700 series is designed for medium duty cycle operation in industrial and R & D environments. These lasers deliver high power ultraviolet laser machining combined with state-of-the-art performance. They are ideal for applications such as pulsed laser deposition.

The physical distance of camera-to-subject changes your depth of field for the same reasons as your aperture and focal length.

Low aperture number, (you can fake this by zooming in if your lens doesn’t go below 3.5), lots of space bewteen subject and background, and zoom in (even with a low aperture lens.) Frankly they don’t explain this very well in an article this long and even get some things…wrongish

This is used to measure lens precision. Once you’ve calculated the circle of confusion, you can then accurately determine how precise the focus of your lens will be, and paired with the focal length, you can determine the hyperfocal distance of a particular lens.

Here you see some images that have a very shallow DOF. You'll notice how this focuses your attention to specific areas of the image, and has the ability to elicit desired emotions from the viewer.

The magnification of the lens not only simulates being closer to the subject, but it also magnifies the actual blurring effect in the unfocused parts of the image.

The CARBIDE 50 W UV laser is based on the market-proven industrial-grade CARBIDE laser platform. It emits 500 fs pulses at a 343 nm wavelength and fits into a footprint of 84 × 35 cm, making it the most compact 50 W UV femtosecond laser currently available on the market. The CARBIDE ensures long-term performance without the need for user intervention. Its high power allows for beam splitting into multiple parts, enabling parallel micromachining processes and subsequently increasing throughput. The CARBIDE platform ensures simple integration into industrial 24/7 workstations.

You can do this by simply checking the box for DOF on your shot list, and you can mark shallow depth of field, or mark it deep if you need to see imagery that is further back in the frame.

Many applications benefit from central wavelengths in the VIS or UV range. AFS offers fully integrated frequency conversion modules from 1030 nm to 515 nm, 343 nm or even 258 nm. The conversion efficiency depends on the pulse duration of the driving laser. We offer fourth-harmonic generation upon request.

Lens filters can help you control your depth of field in specific instances. This is most useful in those rare moments when you have too much light, but you don’t want to stop down.

If your subject takes up the same amount of space in the frame, you will have the same depth of field regardless of focal length.

It also is a really good way of establishing the value of a lens and its construction, because the smaller the circle of least confusion is, the more precise (possibly expensive) your lens will be.

Ultravioletlaser diode

Neutral density filters don’t change the angle at which light rays enter the lens. They simply reflect a small amount of light so that your exposure is lowered.

Ultravioletlaser pointer

This will help you keep images appropriately exposed despite having the relatively wide aperture that gives you the shallow look you desire.

If you are shooting a scene in particularly harsh, bright light, but you still want to get an image with a shallow depth of field, consider using a neutral-density filter to decrease the light intensity.

Establishing your own visual style should occur before you step on set, and it begins with understanding how to control your depth of field.

This spreads the angle to make it wider, which squishes your field closer together, and thus creates a shallower depth of field.

When you get very near a subject you will notice that your depth of field becomes more shallow. This happens regardless of the focal length of your lens.

96 suppliers for ultraviolet lasers are listed in the RP Photonics Buyer's Guide, out of which 14 present their product descriptions. Both manufacturers and distributors can be registered.

So, whenever an extremely shallow depth of field is used to capture an image, selective focus is at work. An large amount of light is often needed to achieve selective focus, so keep that in mind.

Depth of field (DOF) is the term used to describe the size of the area in your image where objects appear acceptably sharp. The area in question is known as the field, and the size (in z-space) of that area is the depth of that field. DOF is governed by the angle at which light rays enter the lens.

This allows a filmmaker to elicit several different emotions from the viewer. Some of these include severity, loneliness, fear, doubt, extreme beauty, heightened senses, and anger.

HÜBNER Photonics offer UV lasers in the Cobolt 05-01 and 06-01 Series, emitting at 355 nm (single-frequency or Q-switched)) or 375 nm (a continuous-wave diode laser).

If you were to put a longer lens on your camera, it would magnify your subject, and this creates the same depth of field you would get with a wide lens very near the subject. This is why longer lenses appear to give you shallower DOF.

Depth of field is a spectrum and provides a number of variations that bring different effects to different shots. It produces many types of camera focus in film. For a complete breakdown of these options, watch our episode of The Shot List that is dedicated to depth of field and camera focus.

Regardless of the feeling you want to generate, you should make it a point to plan out and shot list the intended depth of field for each shot.

The circle of confusion is the measurement of a point source of light that falls on the focal plane. The diameter of this circle is measured by fractions of millimeters. This light is never truly in focus, which is why size of the circle of confusion is used to determine the quality of a lens. The smallest circle a lens can generate (circle of least confusion) registers a light source in “perfect focus.”

Applications are in chemical and biological detection, water purification, disinfection, skin treatment and fluorescence imaging.

For instance, if you are attempting to film a shot like the one in the video below, you'll want to stay wide, but you also keep a large depth of field.

Sacher Lasertechnik also offers the Jaguar UV laser, a MOPA system with fourth harmonic generation for output wavelengths from 205 nm to 270 nm.

At the very beginning when Henry hands the car keys off to his friend, you'll notice the depth is more shallow. Why? Because the subject was closer to the camera, but as they move through the scene they remain in focus.

In The Night Of, the shallow depth of field not only creates an eerie tone, but it also plays into the detective aspect of the story.
