1.5.

Optical Filters



Compatible with lenses



BANDPASS: Use with UV‐sensitive sensors for UV imaging; passes UV, blocks

visible and



BLUE BANDPASS: Use with blue LED illumination (470nm typ.) to enhance blue
fluorescence resulting from UV excitation. Highlights blue parts and darkens all others for
color separation



GREEN BANDPASS: Use with green LED illumination (520‐535nm
typ.). Highlights green
parts and darkens all others for color separation. Enhances green fluorescence from UV
excitation; passes 505‐550nm wavelengths



BANDPASS: Blocks both UV and IR; passes only visible wavelengths










ORANGE BANDPASS: Use with amber
LED illumination (590nm typ.). Enhances orange
fluorescence from UV excitation; passes 560‐620nm wavelengths. Highlights orange parts
and darkens all others for color separation



LIGHT RED BANDPASS: Use with light red LED (620‐645nm typ.) or structured lase
r diode
lighting (635nm typ.). Highlights red parts and darkens all others for color separation



DARK RED BANDPASS: Use with dark red illumination or structured laser diode lighting
(660nm typ.). Highlights red parts and darkens all others for color separat
ion



INFRARED BANDPASS: Use with IR LED illumination (850 or 880nm typ.). Use to remove
visible portion of ambient light and view unique IR spectral characteristics



LINEAR POLARIZER: Use to remove glare from non‐metallic objects.



ROTATING FILTER: Use as a
neutral density filter in bright ambient light conditions



LIGHT BALANCING: Use with white LED, metal halide and xenon strobe lighting to remove
strong blue component and achieve accurate color rendition



LINEAR POLARIZER SHEET: Cut to fit over light source
and “cross” with PR032 mounted on
camera 4” x 5” x .007” lens for maximum benefit
