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.
G32503 is a tight-band green filter that peaks near 500 nm, delivering vivid green output while keeping UV/blue, yellow–red, and most mid-IR energy out of the beam. Transmission climbs past 90 % around 460 nm, holds >90 % through roughly 514 nm, and falls below 1 % by ~550 nm. A secondary rise appears beyond 700 nm, reaching ~80 % at 735nm before tapering toward 750 nm. The spectrum is perfect when you need saturated green but still want an optional NIR “peek” for alignment or dual-band imaging.
Key advantages
Tight 460 – 514 nm passband – >90 % peak transmission maximises green luminance and colour fidelity.
Deep out-of-band blocking – < 1 % T from 560 – 677 nm and < 0.5 % below 460 nm suppresses red flare and UV/blue noise.
Built-in NIR window – Controlled ~80 % transmission at 735 nm enables alignment beacons or secondary channels without extra optics.
Flexible formats – Round, square, or free-form blanks from 5 mm to 450 mm, 0.21 – 3.8 mm thick, on Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG glass.
Typical applications
Fluorescence microscopy & cytometry – Deliver FITC-style excitation while dumping autofluorescence and IR.
Machine-vision illumination – Pair with green LEDs or lasers to boost SNR in reflective-part inspection.
Projection & display engines – Channel green primaries cleanly in laser-phosphor or RGB-LED light paths.
Multispectral & hyperspectral cameras – Provide a discrete green channel with an NIR reference for vegetation indexing.
Stage & architectural lighting – Create razor-saturated green beams or washes that stay bright on stage without heating gels, while the NIR notch helps maintain camera-friendly contrast.
Augmented-reality waveguides – Inject bright green imagery into see-through combiners while keeping the substrate cool.
