Optical interference filters and optical coatings in general are one of the highest efficiency products made. Most optical thin film coatings have energy loss of less than one part per million, and...

Below are some guidelines as to how best to find a filter or coating that meets your specific need. The most significant characters in the SKU are the 2 nd through 5 th characters. These define the...

A principal limitation to the use of optical filters is that they are most effective when used in a collimated beam of light. This requires that for optimum performance the filter can not accept a...

Optical interference filters are made by depositing a complex stack of atomic-dimension layers on a support substrate. When a substrate is coated with a material of refractive index different from the...

Optical thin-film coatings and filters are remarkably high in performance as well as long-lived products. From an efficiency perspective, optical filters can isolate a transmitted wavelength band with...

Most contemporary optical coatings are made of refractory oxides of certain metals. Typically, Al, Si, Ti, Ta, Hf, Nb, and other oxides are deposited by either an evaporation process or a sputtering...

Most optical coatings are thin transparent dielectric materials. The performance they achieve is due to the conditions of destructive and constructive interference of light as it attempts to pass...

Although this photography is in the UV spectrum, it is a very long wavelength UV known as UV-A, and therefore will not give the full range of spectral reflective/absorptiv e information that is...

In applications in which an assortment of Visible and IR lasers needs to be co-linearly combined, or a signal of IR and Visible information needs to be resolved, a beam combiner is required....
