Coated filter

Coated filter

The coated filter is coated on the substrate

To realize the characteristics of transmitting a certain wavelength or wave band

Made by the principle of film interference

By changing the optical parameters such as film structure and number of layers

Various spectral characteristics can be obtained

Used to control, adjust, and change light waves

Transmission, reflection, absorption, polarization or phase state

The coated filter has a wide range of applications

With the deepening of optical research in all aspects

It is widely used in organic chemistry

Polymers, biology, surface and film

Coating filter according to the film material

It is divided into hard film filter and soft film filter

Hard film filter refers not only to film hardness

More importantly, its laser damage threshold is high

So it is widely used in laser systems

Soft membrane filter is mainly used for biochemical analyzer

The coated filter can be divided into:

Narrow band interference filter, multi band pass filter, Short wave pass filter, long wave pass filter, band stop filter
