Optical Filters

Adoption of IBS coating technology and higher damage threshold Read more...

CeNing Optics provide a variety of colored glass filters covering the UV, visible and near-infrared wavelength regions. These filters serve as bandpass, broadband, or long-wave pass filters. Read more...

Alluxa's ULTRA Series filter sets provide better overall performance than our standard filter sets by using a combination of tight wavelength control (typically ± 1 nm), ultra-steep edges, deeper blocking, and the industry's highest transmission levels. Alluxa is the leader in optical filters and optical coatings. Read more...

Next-generation thin-film optical filters offer improvements in transmission, blocking, and both transmitted and reflected wavefront properties. This translates into bright, high-contrast images and accurate detection of target molecules. Read more...

The HELIX Spectral Analysis System has redefined measurement capabilities of high performance thin-film optical filters. HELIX is an instrument designed and developed by Alluxa Engineering staff to address the limitations of most commercially available spectrophotometers. Read more...

Germanium wafers are a semiconductor material and therefore are a great choice for microelectronics. Due to its unique electric properties, it is widely used for sensors, solar cells and infrared optical applications. Read more...

Abrisa Technologies carries a large inventory of cost-effective solid colored glass for aesthetic use in the lighting and entertainment, architectural, and landscaping applications. The soda lime glass can be heat strengthened “tempered” for additional thermal shock resistance. Read more...

Deposit thin layers of metallic or dielectric material on a lens, mirror or other optical device, and what’s left is a thin-film optical coating. Such coatings are applied to control transmission or reflection properties through the mechanism of optical interference. Many types are available for specific applications and optical equipment. Read more...

When it comes to a high quality IR Cut filter, it is the substrate with the coating applied that affects the performance. Knight Optical provide high quality wafers for precisely this, and the surface quality of our substrates eliminates blotching at the sensor Read more...

Gas Detection Systems use Interference Bandpass Filters to identify the emission of a type of gas. Different gases emit at a specific wavelength which makes it identifiable when using a relevant Interference Bandpass Filter. These wavelengths are: Read more...
