G9017 harvests maximum light where human vision and many sensors are most
sensitive. Transmission clears 90 % just past 500 nm, hovers between 90 – 95 % to
~555 nm, then plummets below one percent by ~595 nm. Below 475 nm it also sits
under one percent, yielding a vivid, glare-free green channel with excellent isolation from
UV/blue and yellow-red spill. KUPO can flatten the minor < 8 % ripple near 393 nm
on request.
KUPO coats Borofloat®, soda-lime, Schott D263 T, or Corning Eagle XG substrates cut to 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/GFP fluorescence excitation, green-LED or laser machine vision,
RGB laser/LED projection, discrete green bands in multispectral cameras, saturated stage
lighting, and AR/HUD waveguides that need bright green injection without UV/IR heat.
Description
The G9017 delivers a substantial 70 nm passband spanning green through yellow with 94.9 % peak transmission at 543 nm. This broad-aperture filter achieves outstanding blocking at both spectral extremes, establishing it as the optimal choice for applications requiring maximum green-yellow collection without sacrificing spectral purity.
