Y10103 Hybrid delivers Passband 524 – 780 nm, 91.2 – 95.5 % T (± 2.1 % ripple), Cut-on (T50) ≈ 513 nm, and Edge steepness ~24 nm (10 → 90 % transition).
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
GFP and FITC fluorescence, green-channel microscopy, removal of blue scatter in spectroscopy, daylight-to-tungsten color correction, and machine-vision applications requiring green isolation.
Description
The Y10103 cuts on at 512.9 nm, blocking UV through the blue-cyan band while transmitting from green through the near-infrared. The passband averages above 94 % from 520 to 780 nm, peaking at 95.5 % near 691 nm. Blocking holds below 1 % from 380 to 494 nm, suppressing the entire UV-through-blue spectrum with OD 2+ rejection. This is a classic green-onset longpass filter suited for emission collection, color separation, and warm-tone isolation.
Key Advantages
- 513 nm cut-on for green-edge pass - T50 % at 512.9 nm opens the passband right at the green onset, capturing the full warm-visible and NIR spectrum.
- > 94 % average from green to NIR - Flat passband averaging 94.5 % with peak 95.5 % ensures minimal insertion loss across 260 nm of bandwidth.
- Complete UV-blue rejection - Average transmission 0.4 % from 380 to 494 nm provides thorough suppression of short-wavelength interference.
- Hard-oxide durability - Ion-assisted sputtered coating resists heat, humidity, solvents, and mechanical cleaning.
- Custom formats - Round, square, or free-form blanks from 5 mm to 450 mm, thickness 0.21-3.8 mm, on Borofloat, soda-lime, Schott D263 T, or Corning Eagle XG substrates.
Typical Applications
- Fluorescence emission collection - Passes green through NIR emission while blocking 488/405 nm excitation lines - ideal for GFP, YFP, and multi-label experiments.
- Vegetation & crop sensing - Captures green reflectance, red-edge, and NIR bands for NDVI and chlorophyll indices in agricultural monitoring.
- Machine vision warm-light imaging - Isolates green-through-red illumination for inspection tasks where UV-blue scatter reduces contrast.
- Color separation in printing QC - Defines the warm-visible channel for color matching and quality control in print production.
- Solar simulator filtering - Passes solar-relevant visible and NIR wavelengths while blocking UV for material aging studies.
