Ask RP Photonics for advice on various kinds of optical filters.

Definition: devices with a wavelength-dependent transmission or reflectivity

An optical filter is usually meant to be a component with a wavelength-dependent transmission or reflectivity, although there are also filters where the dependence is on polarization or spatial distribution, or some uniform level of attenuation is provided.

Types of Optical Filters

There are many different types of optical filters, based on different physical principles. Some examples of optical filters are:

Concerning the shape of the transmission curve, there are

Applications

Examples of applications of optical filters are:
