Sputtered Metal Deep-UV Interference Filters
Chroma Technology Corp.Request Info
Chroma Technology’s sputtered metal UV interference filters offer the highest levels of Deep UV transmission of any UV metal coated filters available.
Coupled with the broad out-of-wavelength blocking provided by metal filters ( >OD4 through the Deep-IR), they’re excellent choices for transmitting UV mercury and cadmium lines from discharge lamps, excimer lamp and laser lines, nitrogen lasers and for Raman applications and Deep-UV fluorescence microscopy.
Manufactured using single substrates of UV-grade fused silica and backed by Chroma’s generous warranty, these filters are currently available in 11 different passbands in a wide range of sizes, from 2mm-200mm. Many various combinations of center wavelength and bandwidth can be custom manufactured, from small volume prototypes to full production runs.
These highly durable filters have laser damage thresholds >0.15 J/cm2 using a 355nm laser (10 ns pulse, 10 Hz), and suffer no degradation after 2 hours @ 300ºC.
