The principle and application of biphasic mirrors

A dichroic mirror is an optical element whose core principle is the ability to selectively reflect or pass through specific wavelength bands of light beams based on their wavelength.

This type of mirror is typically composed of multiple thin film coatings designed to reflect light at specific wavelengths while passing through other wavelengths. The working principle of biphasic mirrors is based on thin film interference and reflection, which are commonly used in laser technology and optical instruments. Such as enzyme-linked immunosorbent assay instruments, fluorescence microscopy systems, projection light engine systems, etc. Biphasic mirrors can separate ormerge light of different wavelengths, and they can reflect or absorb specific colors or bands of light in a composite beam,thereby achieving control and adjustment of the optical path.
