KOPP UV Transmitting Filters

Ultraviolet Bandpass Filters (Ultraviolet Transmitting - Visible Absorbing)

KOPP 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. KOPP produce filters that are tailored to industry applications with many glasses targeting high transmission at 254 nm and 365 nm.
