A laser polarizing beamsplitter cube consists of a pair of high-precision right-angle prisms that are cemented together with a dielectric coating on one of the two diagonal surfaces for splitting a randomly polarized laser beam. Laser polarizing beamsplitter cubes transmit p-polarized light and reflect s-polarized light. We offer a large selection of laser polarizing beamsplitter cubes, optimized for various wavelengths and laser types.

BK7, H-K9L, Sapphire, UV-grade fused silica, IR-grade fused silica, calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), zinc sulfide (ZnS), gallium arsenide (GaAs), germanium (Ge), and silicon (Si) are some of our many substrate choices.

A camera with a large F-stop has a large DoF. It will also require slower shutters speeds so more light enters the sensor, producing images with deeper depths of field. On the other hand, a camera with a small F-stop has faster shutter speeds so less light enters the sensor. This helps produce images with shallow depths of field.

Narrow your aperture by setting your camera to a large F-number. Then, move farther away from the subject and shorten the focal length.

The aperture setting ranges from f/1.8-f/64 and you have to use the right lens to capture different aperture ranges. A wider aperture (f/1.4, f/2, etc.) helps create a blurred or soft focus image. On the other hand, a narrower aperture (f/8, f/11, etc.) creates a deeper DoF, creates a sharply focused image.

What’s the secret to creating unique, striking images with perfect backgrounds? When composing an image, you have to control the distance between the foreground and the background of the subject that’s in focus. This technique is called Depth of Field (DoF) and it is a powerful principle that separates good photographs from stunning, unforgettable images that look professionally done.

Laser Aspheric Lens: Our laser aspheric lens is meticulously designed to eliminate almost all spherical aberration. With a diameter of 75 mm and a thickness of 35.5 mm, this lens is crafted from high-quality H-K9L material, ensuring exceptional clarity and durability for a wide range of laser applications.

Knowing how to sharpen or soften parts of your images is a great skill to master as an artist. With a shallow depth of field, you can bring the attention to the subject by separating it from the background. This technique is often used in wildlife photography, sports photography, and low light situations. But to focus as much of the scene in a frame, you’ll need maximum depth of field. This technique is often used in landscape photography to bring the viewers’ attention to the entire scene of the image, not just parts of it.

Shanghai Optics manufactures a wide range of high-precision laser optics. Our state-of-the-art equipment allows us to manufacture high-quality optics components that perform consistently under even the most demanding conditions and are suitable for use in CO2 lasers, high-power fiber lasers, solid-state lasers, and laser diodes. Our line of laser optics includes laser lenses, laser line filters, prism mirrors, and laser line beamsplitters.

Our laser line non-polarizing plate beamsplitters are designed to split laser beams 50/50 at a 45° angle of incidence. The beamsplitters exhibit almost no absorption, and the transmission/reflection ratio (50/50) is insensitive to the input beam polarization state. The high laser damage thresholds make the beamsplitters suitable for demanding laser applications. We manufacture laser line non-polarizing plate beamsplitters with 12.5 mm and 25 mm diameters, as well as a 50 mm square variant.

An image’s DoF is measured from the closest in-focus point to the farthest in-focus point. Depth of Field could either be deep or shallow.

On close-up shots, for example, the subject is more focused while the background is usually blurry. In macro photography, images usually have small depths of field. But in landscape shots, the depths of field are larger.

Laser optics includes all the optical elements and optical systems used within lasers or for manipulating—or transmitting—laser light. Laser optics components have more stringent requirements on surface quality and coating compared to standard imaging optics. Surface quality must be high in sensitive laser applications, especially for laser mirrors and prisms. Optical losses must be minimized. Components must have high laser damage thresholds, especially if they are to be used with high-energy pulsed lasers such as Q-switched high-power lasers.

To demonstrate deep DoF, a large depth of space will be shown in subjects such as landscapes. The technique helps make an entire frame appear to be sharp or in focus, from the foreground to the background.

Widen your aperture by setting your camera to a smaller F-number. Move closer to the subject and extend your focal length.

Aperture or F-stop is a camera setting that controls the DoF. The setting controls the amount of light that enters the film or digital sensor through an adjustable opening. The angle of light that strikes the film or sensor changes as the range of aperture changes. Aperture is measured by f-stops, which can be adjusted through the camera controls. The F-stop setting adjusts the ratio depending on the size of the lens that opens as well as the focal length.

Shanghai Optics produces BBO nonlinear crystals using flux technology. These crystals offer broad transparency from 188 nm to 5.2 µm and exceptional phase matching across most of this range. With high power non-linearity, especially in the UV range, and a robust damage threshold of 750 MW/cm² at 1064 nm, BBO crystals excel in various nonlinear parametric applications and high-intensity laser operations.

In filmmaking and cinematography, depth of field gives filmmakers creative control over where the camera is focused on to direct what the audience sees in a scene. The technique helps set up an audience’s expectation in a specific part of the frame to elicit the right level of emotion and attention as the story unravels.

There are many ways to determine a scene’s depth of field. You can either search for DoF charts for your lenses and camera online, download apps that calculate DoF for you, or use your camera’s DoF button for a preview of the image.

Laser optics can be made of a variety of substrates, including BK7, H-K9L, Sapphire, UV-grade fused silica, IR-grade fused silica, calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), zinc sulfide (ZnS), gallium arsenide (GaAs), germanium (Ge), and silicon (Si). Dielectric coatings are often used to improve mirror reflectivity for both S and P polarizations. For most laser applications, filter transmission or reflectance over a very narrow band (the laser line width) is key, and both the substrates and coatings must be chosen carefully to improve the optical performance of the laser-based devices. Ultrashort pulse lasers are the exception; they have a large spectral bandwidth and require lenses and filters with broad transmission ranges.

Shallow depth highlights the main subject of the image by softening the background or putting it out of focus. This technique is usually applied in portraits. By blurring the background, the visual distractions are minimized, allowing observers to focus on the main subject of the scene.

A camera can only focus on a small point in a space. Through this technique, you can determine how much of the image is in “acceptable focus” to the eyes. By understanding the intricacies of DoF, you can also focus on your subject and background at the same time.

Telephoto lens, for instance, helps create images with shallow depth of field. Cameras with a wide-angle lens, on the other hand, will produce images with more depth of field

The lens helps control the aperture capabilities of the camera. Lens with high magnification capability produces images with smaller DoF. This goes even with large F-stop settings. The longer the camera lens, the shallower the DoF.

A laser line filter is a narrow bandpass filter that effectively rejects all unwanted out-of-band radiation and ambient light while transmitting only a specific spectral band. They can be used to increase image contrast in laser-based imaging applications or to prevent signal distortion in laser measurement devices. Shanghai Optics produces laser line optical filters covering laser wavelengths from UV to visible to infrared light. Laser filters feature ultrahigh transmission (T > 90%) at laser wavelengths and greater optical density (OD > 5) in the blocking regions.

The distance of the subject will determine the depth of field of an image. Generally, the closer the subject is to the camera, the shallower the depth of field becomes. The further away the subject is to the camera, the deeper the depth of field becomes.
