Narrow green filter (509 – 543 nm, > 90 % T) with strong UV/blue & red blocking plus an optional >90 % IR window near 770 nm.
G73607 passes a vivid slice of pure green while suppressing nearly
every other colour until the deep IR. Transmission crosses 90 % near 509 nm,
stays above that figure to ~543 nm, and drops below one percent before 585 nm.
UV/blue remains in the noise up to the green edge, and the yellow-to-red band is
suppressed until a second window opens above 777 nm where transmission again
exceeds 90 %. Perfect when you need saturated green plus an optional IR “peek”
for alignment or dual-band sensing.
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 cameras (green + NIR reference), saturated
stage beams, and AR waveguides that need bright green injection alongside IR
tracking signals.
G73607 passes a bright slice of pure green while suppressing nearly everything else until the deep-IR. Transmission crosses the 90 % line near 509 nm, stays above 90 % through roughly 543 nm, and drops below 1 % by 585 nm. UV/blue energy remains in the noise up to that green edge, and the whole yellow-to-red region is pushed down to detector dark until a second window opens above 777 nm, where transmission again exceeds 90 %. If you need saturated green with an optional IR “peek” for alignment or dual-band sensing, this spectrum fits the bill.
Key advantages
Tight 509 – 543 nm passband – > 90 % transmission delivers vivid, high-brightness green.
Deep broadband blocking – < 1 % T from 400 – 480 nm and 584 – 730 nm eliminates UV/blue noise and red flare.
High IR window – > 90 % transmission around 770 nm provides a built-in channel for NIR reference or beam alignment without extra optics.
Hard-oxide durability – Ion-assisted coating shrugs off heat, humidity, solvents, and repeated cleaning.
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 – Excite FITC-like dyes while dumping autofluorescence and IR.
Machine-vision illumination – Pair with green LEDs/lasers to maximise signal-to-noise in reflective inspection.
Projection & display engines – Cleanly channel the green primary in laser-phosphor or RGB-LED light paths.
Multispectral & hyperspectral cameras – Supply a discrete green channel with an NIR reference for vegetation or stress indexing.
Stage & architectural lighting – Produce razor-saturated green beams or washes, with the IR notch available for follow-spot tracking systems.
Augmented-reality waveguides – Inject bright green imagery while leaving bandwidth for NIR tracking signals.
Fast prototypes or volume production—G73607 filters can be coated, diced, and shipped to your exact specifications on the schedule you need.
