Y10001 Hybrid delivers Passband 492 – 780 nm, 91.2 – 95.5 % T (± 2.1 % ripple), Cut-on (T50) ≈ 481 nm, and Edge steepness ~24 nm (10 → 90 % transition).
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Blue LED filtering, GFP fluorescence collection, blue-glare suppression in machine vision, daylight sensor protection, and spectroscopy applications requiring blue light rejection.
Description
The Y10001 blocks ultraviolet and violet light with its 50 % cut-on at 480.6 nm, then passes the entire visible and near-infrared spectrum from approximately 488 nm to 780 nm with average transmission exceeding 94 %. The passband peaks at 95.5 % near 776 nm while the blocking region holds below 1 % from 380 to 462 nm, averaging just 0.5 %. This cyan-onset longpass opens the optical path to green, yellow, orange, red, and NIR energy while thoroughly rejecting UV and violet.
Key Advantages
- 481 nm cut-on with > 94 % passband - T50 % at 480.6 nm transitions sharply into a flat passband averaging 94 % from 488-780 nm.
- Deep UV-violet blocking - Transmission stays below 1 % from 380 to 462 nm, suppressing UV and violet with OD 2+ rejection.
- Flat spectral response to 780 nm - Passband ripple constrained to under 2 %, ensuring uniform signal across green through NIR.
- Hard-oxide durability - Ion-assisted sputtered coating resists heat, humidity, solvents, and repeated cleaning without spectral drift.
- 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 - Blocks violet excitation light while passing green-through-NIR fluorescence emission, maximizing signal-to-background in widefield microscopy.
- Machine vision color filtering - Removes UV and violet scatter from broadband imaging, improving contrast on reflective or UV-fluorescent surfaces.
- Stage & architectural lighting - Produces warm-toned washes by stripping violet content from white sources, shifting perceived color temperature.
- Solar energy & photovoltaic testing - Passes the solar-active visible and NIR spectrum while blocking UV degradation wavelengths in accelerated aging studies.
- Display calibration - Defines a broad green-through-NIR detection window for display luminance and color uniformity testing systems.
