Narrow green filter (510 – 525 nm, > 90 % T) with strong UV/blue & red blocking plus an optional 55 % NIR window around 750 nm.
G73608 passes a vivid slice of saturated green while pushing nearly
every other wavelength down to the noise floor. Transmission clears 90 % near
510 nm, stays above that level to ~525 nm, and dives below one percent by 565 nm.
UV/blue remains suppressed up to the green edge, and yellow-through-red energy
stays near zero until a controlled secondary window rises beyond 720 nm, peaking
around 55 % at ~750 nm—ideal for alignment beacons or dual-band imaging.
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 roughly 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 that need bright green injection plus
an IR tracking channel.
G73608 passes a narrow slice of saturated green while pushing almost every other wavelength down to the noise floor. Transmission clears the 90 % mark near 510 nm, holds above 90 % to roughly 525 nm, and dives below 1 % by 565 nm. UV/blue energy stays suppressed up to the green edge, and yellow-through-red light remains near zero until a modest secondary window rises beyond 720 nm, peaking around 55 % at about 750 nm before tapering toward 780 nm. Use it whenever vivid green is required but a small NIR “peek” is handy for alignment or dual-band sensing.
Key advantages
Tight 510 – 525 nm passband – > 90 % transmission delivers high-brightness, colour-pure green.
Deep broadband blocking – < 1 % T from 400 – 490 nm and 565 – 704 nm suppresses UV/blue noise and red flare.
Built-in NIR window – ~55 % transmission near 750 nm provides an alignment or reference channel without extra optics.
Hard-oxide durability – Ion-assisted coating withstands 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-type dyes while dumping autofluorescence and IR.
Machine-vision illumination – Pair with green LEDs/lasers to maximise signal-to-noise in reflective-part inspection.
Projection & display engines – Cleanly channel the green primary in laser-phosphor or RGB-LED light paths.
Multispectral & hyperspectral cameras – Supply a discrete green band with an NIR reference for vegetation or stress indexing.
Stage & architectural lighting – Produce razor-saturated green beams or washes without heating gels, with the NIR notch available for tracking systems.
Augmented-reality waveguides – Inject bright green imagery into see-through combiners while leaving bandwidth for NIR tracking signals.
