A dichroic filter is an optical filter designed to separate light into two distinct wavelength bands.
There are two main types of dichroic filters: absorption-type and interference-type. Absorption-type dichroic filters absorb light within two different wavelength bands. Conversely, interference-type dichroic filters utilize the interference of light to achieve wavelength separation. These filters are constructed by layering two thin films, allowing only light of a specific wavelength to pass through.
Dichroic filters find applications across various fields including optical instruments, optical measurement devices, and optical materials. By selectively transmitting light of a particular wavelength, they enhance color representation in cameras and microscopes, mitigate backlighting, and highlight specific components of observed objects in microscopy. Optical measurement devices, facilitate the measurement of wavelength characteristics of objects and are integral to the manufacturing and evaluation of optical materials.
