There is a large choice of filters, their characteristics are thoroughly differentiated.
To choose the right filter characteristic may help you to increase your experimentation efficiency.
The filter structure can be simple to be replaced, prepare many filters for replacement to obtain the best optical experimentation condition.

Application	Sample of use	Products		Features
Brightness adjustment	Prevention of saturation of sensor Contrast tuning of interference fringes A proper brightness adjustment Laser security measure		Absorption ND filter Reflectance ND filter Variable ND filter	Low cost High power laser, wide wavelength Continuously variable
Choice of wavelength(color)	Fluorescence observation Select a single color light Infrared and Ultraviolet observation		Color glass filter Dichroic filter Bandpass filter	Low cost, low ripple and high light cut-off High transmittance High steep of reflectance and transmittance switching Small bandwidth wavelength selection
Attenuate the scattered light	Uniformize the light Illumination for Observation Screen		Beam shaping diffuser Diffuser plate	Low lost One direction emission Low cost The selection of proportion of Transmition and Diffusion
