500-1100nm optical filter

Precision long wave pass interference filter designed to transmit wavelengths from approximately 500 nm through 1100 nm (visible yellow-green to NIR) while blocking shorter wavelengths below 500 nm (UV to green).

Fabricated on a 1.1 mm thick optical glass substrate (BK7/K9 or fused silica) with hard dielectric multilayer coating via ion-assisted deposition.

Ideal for fluorescence emission filtering, machine vision spectral separation, biomedical analyzers, and NIR imaging systems where clean separation between visible shortwave and longwave/NIR bands is required. Available in custom dimensions and cut-on wavelengths.
