Did You know?

Optical filters selectively transmit light in a particular range of wavelengths. When designed to pass long wavelengths only, they are referred to as longpass filters. Longpass filters are designed to attenuate shorter wavelengths and transmit longer wavelengths over the active range of the target spectrum. Because they isolate specific wavelengths, longpass filters are desirable in systems where they can be used to trim exess wavelengths or stray light to reduce unwanted near band emissions. Longpass filters are useful in a variety of applications and can be used in combination with shortpass filters for custom bandpass filtering.
