Description
The C11715 passes UV through the yellow spectrum with its 50 % cut-off measured at 581.8 nm. Transmission peaks at 95.3 % near 544 nm and averages above 92 % from 393 to 573 nm, providing a nearly 180 nm-wide passband that covers violet, blue, cyan, green, and yellow. Blocking drops below 1 % by 605 nm and averages under 0.6 % through 780 nm. The passband onset softens slightly around 385 nm, with UV-A transmission at approximately 78 %.
Key Advantages
- 582 nm cut-off for warm-edge rejection – T50 % at 581.8 nm passes the entire cool-visible spectrum plus yellow, cutting precisely at the orange boundary.
- Peak 95.3 % with > 92 % average – Nearly 180 nm of high-transmission passband covering blue through yellow for maximum signal collection.
- Deep orange-NIR blocking – Transmission averages under 0.6 % from 605 to 780 nm, rejecting orange, red, and near-infrared contamination.
- Hard-oxide durability – Ion-assisted sputtered coating withstands thermal stress, solvent exposure, 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 glass.
Typical Applications
- Sodium-line rejection – Blocks 589 nm sodium emission in astronomical or street-lighting environments while passing the entire cool-visible spectrum.
- Color-critical photography – Eliminates warm orange-red casts from mixed-source lighting while preserving natural blue, green, and yellow tones.
- Industrial machine vision – Pairs with broadband illumination to remove red and NIR components that cause contrast loss on metallic or glossy surfaces.
- Medical imaging – Passes the visible diagnostic window (violet through yellow) while blocking tissue-scattered red and NIR light.
- Architectural lighting – Creates warm-neutral washes up to yellow but with zero orange or red spill for precise interior color design.
