Product Name Notes
Broadband Interference
Circularly variable neutral density filters are designed to simplify attenuation and beam splitting from VIS to near IR. The optical density gradually varies around a 270 circle for convenient attenuation...
High Performance Interference
Interference filters are fabricated by a series of thin layers of various dielectric materials sandwiched by glass substrates. When multi wavelength light passes through the filter interference occurs due to...
Interference filters are fabricated by a series of thin layers of various dielectric materials sandwiched by glsaa substrates. When multi wavelength light passes through the filter interference occurs due to...
Optical Short-pass Filters are coated on a substrate of fused silica, which allows the transmission of any wavelength shorter than the cut-off wavelength and block any wavelength longer than the...
The metallic coatings on one side of the filter provide a nearly constant amount of transmitted energy over a wide visible and near infrared waveband. CDHC's neutral density filters are...
The substrate materials of the color filters inherently have different absorption and transmission properties across the spectrum. The are often used as long-pass and band- pass filters. It should be...
This ND filters provides linearly varying attenuation or beam splitting in the visible and near infrared region. The optical density varies linearly across the length. Attenuation is achieved by a...
