factory offer optical filter

Factory-customized round short wave pass / cold mirror filter designed to reflect visible blue-green light (400–550 nm) and transmit infrared (>550 nm–1200 nm+),

or conversely configured as a hot mirror (per application — this item is a Cold Mirror: reflects SW, passes LW).

Deposited with high-durability dielectric multilayer coatings on heat-resistant substrate (Borofloat / fused silica / high-temp glass), it withstands elevated temperatures in projection, lighting, and laser systems where IR heat must be removed while preserving visible blue-green reflection/imaging.

Fully customizable in diameter (10–300 mm), thickness, cut-on wavelength (500/530/550 nm), and mounting.
