Tight-band green filter (460 – 514 nm, > 90 % T) with <0.5 % UV/blue and <1 % red leakage, plus an optional 735 nm NIR peek for alignment.
G32503 peaks near 500 nm, delivering vivid green output while crushing stray UV/blue,
yellow-red, and most mid-IR. Transmission climbs past 90 % around 460 nm, holds > 90 % through
roughly 514 nm, and falls below one percent by ~550 nm. A controlled rise beyond 700 nm reaches
~80 % at 735 nm for alignment beacons or dual-band imaging, then tapers toward 750 nm.
KUPO coats Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG substrates in any outline—from
5 mm chips to 450 mm plates—with thicknesses of 0.21 – 3.8 mm, and can ship prototypes in
about two weeks.
Typical uses: FITC-style fluorescence excitation, green-LED machine vision, RGB
laser/LED projection, multispectral vegetation indexing (green + NIR), saturated stage beams,
and AR waveguides needing bright green injection without UV/IR heat.
The G73504 isolates bright green transmission at 510 nm with a 40 nm passband and 93.9 % peak efficiency. Engineered for color-critical applications, this filter achieves exceptional blue-side blocking while maintaining manageable long-wavelength characteristics, positioning it as the standard choice for precision green detection.
