| 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... |
