Kolari Vision 39mm UV Bandpass Ultraviolet Photography Lens Filter

What sets our 39mm UV Bandpass Ultraviolet Photography Lens Filter apart is its innovative design and high-quality construction, specifically engineered for superior UV photography. This durable filter is a perfect companion for a full spectrum converted camera, enabling you to capture true UV images with remarkable clarity and precision.

Our filter stands out in the market due to its absorption-based glass construction, as opposed to the common interference coating-based filters. This unique design ensures consistent color across the frame, eliminating the issues of transmission characteristics changing based on the angle of light rays, a problem often encountered in general photography with interference-based filters.

The filter boasts a 50% transmission peak at 365nm, and >25% transmission between 340-380nm, ensuring high total light transmission. This results in a high signal to noise ratio and no IR contamination, providing you with crisp, clear images every time. The average out of band rejection is >OD 4.3 (0.005%), with a minimum rejection of >3.5OD (0.025%).

Designed with the photographer in mind, this versatile filter is not just great for photography, but also finds application in skin damage analysis, forensic analysis, astrophotography, and more. The filter is coated for durability, protecting the sensitive UV glass from oxidation when exposed to humidity, thereby prolonging the filter's lifespan.

Please note that due to the thickness of the glass, the filter is threaded on one side only. This effective, high-quality 39mm UV Bandpass Ultraviolet Photography Lens Filter is an essential tool for any photographer looking to explore the fascinating world of UV photography.
