O10405 Hybrid delivers Passband 542 – 780 nm, 90.4 – 95.7 % T (± 2.6 % ripple), Cut-on (T50) ≈ 530 nm, and Edge steepness ~28 nm (10 → 90 % transition).
The hard-oxide coating is built for repeated handling, heat, and cleaning.
Best suited for:
Sodium-line isolation in street-lighting analysis, warm-tone stage lighting and photography, amber safety glazing in automotive applications, and yellow-channel imaging in multi-spectral systems.
Description
The O10405 blocks UV through the blue-green band with its 50 % cut-on at 530.3 nm, then transmits from green through the near-infrared with average throughput exceeding 94 %. The passband spans 538-780 nm, peaking at 95.7 % near 715 nm. Blocking holds below 1 % from 384 to 508 nm, with a brief transition zone from 509 to 537 nm. This filter captures the warm-green through NIR window with clean UV-blue suppression.
Key Advantages
- 530 nm cut-on with steep transition - T50 % at 530.3 nm transitions from blocking to > 94 % in under 10 nm, minimizing spectral crosstalk.
- 95.7 % peak with > 94 % average - Flat passband from 538-780 nm with minimal ripple ensures uniform throughput across green-to-NIR.
- Deep UV-blue suppression - Transmission averages 0.6 % from 384 to 508 nm, delivering OD 2+ blocking.
- Hard-oxide durability - Ion-assisted sputtered coating resists heat, humidity, solvents, and repeated 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
- 532 nm laser emission pass - Pairs with 532 nm Nd:YAG lasers - passes the laser fundamental while blocking residual pump and blue ASE.
- Fluorescence emission filtering - Collects green-through-red fluorescence while blocking blue excitation, suitable for FITC and TRITC emission paths.
- Machine vision under green illumination - Isolates green-to-red illumination for surface inspection tasks on materials with strong blue scatter.
- Remote sensing - Captures red, red-edge, and NIR bands for environmental and agricultural monitoring while blocking short-wave scatter.
- Theatrical & architectural lighting - Removes cool blue tones from white sources, producing warm green-through-red wash effects.
