Ultraviolet Glass

Responding to the growth of UV technologies and applications, including UV disinfection and sterilization, Kopp engineered our 9530 UV longpass glass composition. This unique, proprietary glass exhibits high transmission and mechanical durability across the UV-A, UV-B, UV-C, and visible spectrum. The versatile material can be manufactured into complex geometries not feasible with other UV transmitting materials. 9530 UV allows for innovative lens and optic designs resulting in optimized lighting systems that are efficient, aesthetically pleasing and engineered for permanence.

Our ultraviolet (UV) longpass glasses feature high transmission across the UV and visible spectrum with tailored transmission cut-offs ranging from 240 nm to 400 nm. Their high transmission in the visible region provides the glass with a clear, colorless appearance and tint. In many applications, such as in UV curing, high transmission is necessary to increase throughput and improve quality. These glasses have been designed to meet common industry requirements, but we also have the capability to customize compositions for emerging technologies and applications.

Our ultraviolet (UV) bandpass filters are engineered to exhibit high transmittance in the UV-A, UV-B, or UV-C regions. These filters appear nearly black as they absorb almost all visible radiation but actually provide high transmission in the UV wavelengths of light. They are suitable for a wide range of applications, such as non-destructive testing equipment, tanning and phototherapy devices, forensic detection and analysis equipment, and theatrical lighting. We have filters that are tailored to industry applications with many of our glasses targeting high transmission at 254 nm and 365 nm.
