Dichroic Filter
from Shanghai Optics

Dichroic Filters for Every Application. A dichroic filter is thin optical filter crafted to transmit light in only one narrowly defined wavelength band, while reflecting all other wavelengths. These optical filters are also known as thin-film or interference filters. Dichroic filters are typically... [See More]

Cold Mirror, 25mm diameter x 3mm thick
from Andover Corporation

A Cold Mirror is the inverse of the Hot Mirror, it reflects the visible and transmits the infrared. Their coatings are all first-surface variety and like the hot mirrors, are also deposited onto low expansion material such as borosilicate glass. These mirrors are usually used at a 45 ° angle of...

Long Wave Pass Trim Filter (LWP)
from Abrisa Technologies

Long pass filters block a select band of shorter wavelengths. This example, long wave pass cutoff filter provides average reflectance more than 99% from 400-700nm, 50% cutoff point at 750nm ±10nm and 95% transmission from 780-1200nm. Custom long wave pass filters are available on request. [See More]

UV Cold Mirror, 25mm diameter x 3mm thick
from Andover Corporation

Ultraviolet Cold Mirrors are slightly different than the standard Cold Mirror whereas they efficiently reflect the ultraviolet and transmit the visible and infrared. They are normally used at an angle of 45 ° and are excellent for applications where one wants to separate the ultraviolet from... [See More]
