Our laser safety filters are made from polycarbonate or glass and we also carry a range of alignment laser filters and speciality laser filters.

Each pair of laser safety goggles or laser safety glasses is supplied with a protective hard storage case and a microfibre cleaning cloth so you can keep your laser safety glasses safe when not in use.

Essentially, focal length is the angle of view, or how much of the scene will be captured and the magnification of the image. The longer the focal length, or the higher the mm of the lens, the narrower the angle of view is and the higher the magnification of the image. The shorter the focal length, or the lower the mm of the lens, the wider the angle of view and the lower the magnification of the image.

A wide angle lens is any lens that has a short focal length: shorter than 24mm. So, lenses from 14mm-24mm are considered wide angle lenses.

The commonly accepted focal length of our eyes is around 22mm-24mm. Our visual attention is about 55 degrees wide. So, on a 35mm full frame DSLR, this gives you a 43mm lens. This focal length provides exactly the same viewing angle as a human eye.This is why many photographers and cinematorgraphers find a 50 mm lens pleasing for quality video production, because it is very close to our own eyes.

If you have a 35mm lens for a full-frame camera, and put it on a crop sensor camera, it’s effectively a 50mm lens. This is because crop-sensor cameras offer a cropped view of a 35mm format. If you’re shooting with a cropped APSC sensor, then you could purchase lenses that are compatible with your camera and account for the cropped sensor.There are a few common cropped sizes for digital sensors. APSC, Super 35, Micro Four Thirds, Super 16.

Operating a laser with the incorrect laser safety glasses can permanently damage your eyesight and you must not operate the machine if you are not sure that the glasses you have are a match for the laser beam you are using.  Contact us immediately if you feel your protection is not adequate.

A telephoto lens generally has a focal length of 60mm or longer. This goes for both prime and zoom lenses. You can have a telephoto prime lens, and a telephoto zoom lens.

When you use a camera with a crop sensor, it affects how the lens works on the camera, measured by its multiplier. For example, a crop sensor could have a 1.5x multiplier. When you attach a 50mm lens, the focal length is multiplied by 1.5x. So, this means a 50mm lens acts like a 75mm lens on a crop sensor DSLR. This essentially crops out the edges of the frame, which increases the focal length.

The optical density (OD) and LB-Rating (where applicable) for each of our laser filters for specific wavelength ranges are shown on the product pages so you can find exactly what you need.

Your laser operational manual or certified laser safety officer (LSO) will be able to determine the correct wavelength range that your laser safety eyewear must cover to ensure your safety.

Our frames are comfortable and stylish and will work to protect your eyes against damage caused by laser wavelengths.  If you are search for a durable line of laser safety glasses and goggles, then look no further.

A macro lens is used for taking photo or video extremely close to a subject. With a macro lens, you can fill the entire frame and have everything be in focus. Most zoom lenses and prime lenses wouldn’t be able to focus this closely on a subject, blurring the image. Macro lenses are generally telephoto, typically with focal lengths from about 100 to 200 mm.

Safety Protection Glasses can provide you with suitable laser safety glasses that cover a range of laser wavelengths.  We work across many industries with our laser glasses including medical, industrial, research, education and military applications and have expertise in all.

Our laser safety eyewear has been refined over many years and we have been market leaders in design and manufacture for many years.  Our great selection of laser filters will suit any wavelength of laser that you may have, and this means that you can always be assured that you will find a laser filter and a suitable frame that works to provide you with great protection.

The laser safety eyewear we provide protects your eyes from dangerous reflected or scatter (laser) radiation from Class 3R, Class 3B and Class 4 laser systems.

The main difference is that a zoom lens has a variable focal length while a prime lens has a fixed focal length. Here’s more on the differences:

Full-frame refers to a DSLR camera with an image sensor that is the same size as 35mm format film, measuring 36 x 24mm. For comparison, the more popular APS-C sensor size found in most DSLRs measures 22 x 15mm. Full-frame sensors have more than 2.5 times the surface area of an APS-C sensor. When you compare a crop sensor and a full-frame sensor, the most noticeable difference between full frame and crop sensor is their field of view. If you put a 35mm lens that’s designed for a full-frame camera on a crop sensor the field of view will be cropped in. Speaking of crop sensors, let’s jump into what a crop sensor is and how it affect your images.

When you compare a crop sensor to a full-frame sensor, the most noticeable difference is how much of what you’re seeing is being captured by the sensor.

To avoid the wrong glasses being used for the wrong laser type we have pad printed the wavelengths directly onto the glasses frame.  We also provide custom pad printing, please contact us for details.

Focal length is the main optical property of a camera lens. It’s displayed in millimeters and by a number that looks like this: 35mm, 50mm, or 100mm. Lenses are named by these numbers and used when refferencing different types of lenses.

A single number, like 24mm, on a lens represents a prime or fixed lens. This means the lens isn’t capable of zooming. A 24mm prime lens is made for only a 24mm focal length. If you want a range of focal lengths, you could use a different lens, like a 24–70mm zoom lens, which gives you the ability to change your focal length in the range of 24mm to 70mm.

We have engineered our laser filters over many years with our customers to ensure that we have produced filters with the maximum visible light transmission and functionality for your laser machine.

If you do not have an LSO within your workplace and cannot locate your laser operational manual and you are not familiar with what type of laser beam your machine operates with, please contact our Laser Safety experts for assistance in choosing the correct coverage for your application.  You will require the information that is found on the label attached to your laser machine, simply take an image of it and send it to one of our laser experts who will then advise you which laser filter you require.

Crop sensor refers to a DSLR sensor that mimics a full-frame 35mm format, but is not a true 35mm format. If you’re using a crop sensor camera, it basically is a “cropped” view of a full-frame 35mm camera.

A prime lens has a fixed focal length (e.g., 35mm). This means you only have a 35mm focal length on one lens. Like a zoom lens, a prime lens has its own pros and cons:

A zoom lens has a variable focal length (e.g., 16–35mm). This gives you a wide variety of focal lengths in one lens. There are pros and cons to having a zoom lens:

The main difference is that a wide angle lens has a short focal length and a telephoto lens has a long focal length. Here’s more on that:
