UV glue is composed of various monomers and oligomers that are mixed with photoinitiators. When exposed to UV light, these photoinitiators initiate a reaction that causes the monomers and oligomers to crosslink and form a strong bond.

If mistakes or spills occur during the bonding process, it is important to act quickly to avoid permanent damage. Use a clean, dry cloth to carefully remove any excess glue, being careful not to smear the adhesive or damage the surfaces. If necessary, use a solvent recommended by the manufacturer to dissolve the adhesive.

By using the right techniques and handling mistakes carefully, you can achieve successful bonding with UV glue. In the next section, we will discuss how to care for the bonded surfaces after bonding is complete.

As far as I can tell, it is correct. I just plugged some values into other online FOV calculators and the FOV calculator in the most popular photography iPhone app and all got the same answers that are in my table. 36mm is the width of a full frame sensor.

If you want to use the field of view equation on this page to calculate the field of view for a sensor size other than the four that have been provided, you’ll need to refer to use this list of common sensor sizes and their crop factor.

In addition to surface preparation, it is important to take safety precautions when working with UV glue. This includes wearing gloves and eye protection to avoid skin or eye contact with the adhesive, as well as ensuring proper ventilation in the work area. For example, if you are working with UV glue in a small, enclosed space, you would want to open a window or use a fan to ensure proper air flow.

I need to shoot down on a square card table, 35 inches on each side (including margins) at a distance of about 1 meter. I am using a Panasonic G6 with the 14-42mm kit lens set at 14mm. Online calculators using the formula FOV (rectilinear) = 2 * arctan (frame size/(focal length * 2) indicate that the 14mm focal length should cover 35.14 inches in the vertical dimension at a distance of 41 inches. When I actually tried it, I had to be at least 11 feet back from the table. What gives?

Dan, I’m a newbie to landscapes, and I’m not a professional. So, here’s a little feedback. Please understand that I don’t necessarily have the right language to ask the right questions. What I was really looking for is a way to know what general lens size to use to get a “how large a field of view. The math is helpful, but really not intuitive, especially if your last experience with higher math was 30+ years ago. What was a very useful visual for demonstrating angle of view is the first illustration you had, namely, the “topdown” view of the camera with cones coming forward in different colors. A visual chart or series of charts showing an object at say 200 yards, with the focal point in the center, and a second overlay on top of that showing how much distance to the front & back of the focal point remains in focus relative to the aperture would be ideal. I realize you are probably laughing out loud at this, & don’t have anywhere near enough time for a project of that size, & probably even less inclination to actually do it, but it would be enormously helpful, and a lot more visually intuitive. Thanks so much.

Since the equation for field of view contains the sensor width, which determines the crop factor of a sensor, this is another way to see the effect that the crop factor of a camera has on an image. The smaller the sensor, the larger the crop factor, and the smaller the field of view for a given focal length. Below I have included data for full frame field of view, as well as the three most common digital crop factors. If you want to learn more about crop factor, you can read my tutorial: How To Calculate a Camera’s Crop Factor.

I am interested because I have two fisheye Zuiko lenses from OM-2 & 4 cameras which I would like to use with adapter on Panasonic G 85 or Canon M 50. Can you help? TIA

In conclusion, UV glue is a powerful adhesive that can create strong bonds between a variety of surfaces. By properly preparing the surfaces, applying the adhesive using the right techniques, and taking care during the curing and post-bonding stages, you can achieve successful bonding with UV glue.

Finally, you will need to gather the materials needed for bonding. This includes the UV glue itself, a UV light source, and any other tools or materials needed for the specific bonding project. For example, if you are bonding two pieces of plastic together, you may need to use clamps or tape to hold the pieces in place while the glue cures.

Another important technique is using a UV light source to cure the adhesive. This ensures that the glue is fully cured and the bond is strong. Additionally, it is helpful to use clamps or other holding devices to keep the surfaces in place while the adhesive cures.

I’ll be honest Michael, I don’t have time to do the math for you. The idea was to create a resource for people to calculate this themselves. All the equations you need are right here on the page. Just plug your numbers in 🙂

Thanks for the suggestion Kay. I like the idea, but there are many phone apps out there that offer this already, and they do a better job than I could ever do. I would suggest buying the app called “PhotoPills”, it has angle of view and depth of field calculators in it and it’s a great app for many things related to photography.

As I continue to build out the photographic knowledge base on the site with articles like Understanding Neutral Density Filter Names and Numbers, and Understanding Aperture, I thought I’d write a quick post about how to calculate field of view for a photographic lens. Lenses are usually described by their focal length, expressed in mm, but how does this translate to field of view?

After the surfaces have been bonded with UV glue, the adhesive must be cured to achieve full strength. Curing involves exposing the bonded surfaces to UV light for a specific period of time, as recommended by the manufacturer. During this time, the photoinitiators in the adhesive react to form a strong bond.

Once the adhesive is fully cured, it is important to properly care for and maintain the bonded surfaces. This may include avoiding exposure to extreme temperatures or harsh chemicals, as well as regularly cleaning the surfaces to prevent buildup of dirt or contaminants. For example, if you have bonded two pieces of metal together, you may want to regularly clean the surface with a soft cloth and a mild detergent to prevent corrosion.

As well as calculating the angle of view, we can also use the same trigonometry to calculate the field of view as a linear measurement, as long as you know the distance to your subject, or, if you know the size of your subject and the focal length you are going to use, it could tell you how far away from it you need to be to get it to fill the frame. The units of measurement will be constant in the equation, so if you use metres as your distance to subject, the linear field of view will also be in metres.

By properly preparing for bonding with UV glue, you can ensure that the surfaces are clean and free from contaminants, safety precautions are taken, and all necessary materials are gathered before beginning the bonding process.

Other helpful tips for successful bonding include keeping the work area clean and free from dust or debris, avoiding excess adhesive that can cause mess or impede bonding, and following the manufacturer instructions for curing times and other important factors.

In this guide, we will discuss the proper usage and bonding techniques for UV glue. We will cover the composition and workings of UV glue, preparation for bonding, application techniques, curing and post-bonding care. By the end of this article, you will have a solid understanding of how to use it for successful bonding.

The larger the field of view, the wider the lens is and the more of a scene you are going to see with your camera. Telephoto and super telephoto lenses have very small fields of view, just a few degrees, so they aren’t able to see very much of the scene in front of them, although the compensating virtue is that what they do see, is much larger in the frame. A wide angle lens for landscape photography has a very small focal length, and therefore a large field of view that lets you record broad landscapes in a single shot.

Factors that can affect curing time include the thickness of the adhesive layer, the type and intensity of the UV light source, and the ambient temperature and humidity. It is important to follow the manufacturer instructions for curing times and to ensure that the surfaces are exposed to the correct amount of UV light.

I would check that your camera is in full output. If you use are using a smaller output resolution, your FoV will be cropped. The frame size input will be smaller.

One of the main advantages of UV glue is its ability to cure quickly, often in just a few seconds, which can save time in production processes. Additionally, UV glue can bond a wider range of materials than traditional adhesives and creates a strong, durable bond. However, it also has some disadvantages, such as being more expensive and requiring special equipment for curing.

Before applying UV glue, it is important to properly prepare the surfaces to be bonded. This involves cleaning the surfaces and ensuring they are free from debris, dust, or any other contaminants. For example, if you are bonding two pieces of glass together, you would want to clean both surfaces with a glass cleaner and a lint-free cloth to remove any dirt, fingerprints, or other residues.

If you read lens specifications (yes, I’m that kind of guy) on manufacturer’s websites, they’ll often quote the field of view (F.O.V) of a lens as well as the focal length. When they do this in photographic terms, they’re talking about horizontal field of view in degrees, and whilst any lens will also have both a vertical and a diagonal field of view, they are rarely talked about in relation to photographic lenses.

UV glue, also known as ultraviolet curing adhesive, is a type of adhesive that is cured by exposure to ultraviolet light. It offers several benefits over traditional or normal adhesives, including faster curing times, stronger bonds, and the ability to bond a wider range of materials. However, to achieve successful bonding, it is important to use UV glue properly.

To achieve successful bonding with UV glue, it is important to use the right techniques. One effective technique is the layering technique, where multiple thin layers of glue are applied and cured separately. This can create a stronger bond than applying a single, thick layer.

Nikon specs their 10-24mm DX lens as having AoV of 109 degrees at 10 mm and 61 degrees at 24 mm when used on a DX camera. This does not agree with your table above. However, using their two numbers, you can easily calculate the sensor size from your formula–it is 28.4 mm. This is exactly the diagonal of the cropped sensor size of 23.5 x 15.7 mm.. Thus, Nikon uses the diagonal for quoting their specs, not the width of the sensor.

Once the surfaces have been properly prepared as suggested above, it is time to apply the UV glue. To do this, simply apply a thin layer of UV glue to one of the surfaces using a brush, syringe, or other applicator. Then, carefully place the second surface on top of the first, ensuring that the surfaces are properly aligned.

It must be noted here that Canon has actually used difference sensor sizes for their APS-C cameras over the years. Since the sensor dimension does affect the field of view, this should be taken into account in order to be 100% accurate. For the data table below I have chosen to use the sensor width of 22.5mm because this is the one that Canon seem to have stuck with for their own calculations, and it is also the dimension that gives exactly a 1.6x crop factor. Whilst they do have 22.3mm and 22.4mm sensor widths on the market as well, this minuscule difference would not actually make any noticeable difference to your images, but if you ran your own calculations for your own camera and found they did not match my numbers, this will be the cause of the difference. It was the source of some head scratching for me when I was figuring all this out myself!

Note that this equation HSize/2=f*Tan(FoV/2) is inaccurate if your DSLR lens has >1% distortion. So, it shouldn’t be used for lenses like the Canon 11mm-22mm and most <15mm EFL 35mm-format type lenses. The G6 14mm has ~5% distortion.
