Plane mirrors
Plane mirrors are usually used for beam steering,interferometry,imaging or ilumination.Glassor metals after surface polishing are used as the substrates,and beams shine on their surfaces and cause specular reflection.
Plane reflectors
Plane reflectors can be used for beam steering and interferometry and as optical elements in imaging systems.The surface flatness and reflectivity are taken as the important parameters .High surface precision can reduce the light loss due to dispersion.

Cold/hot reflectorsWith visible light and infrared light in the light source or light signals,cold/hot reflectors can separate visible light and infrared light and reflect/transmit visible light only,reducing system temperature rising problems due to infrared radiation. In terms of spectral characteristics,hot reflectors have high transmittance for visible light and high reflectivity for near-infra- red light,and cold reflectors have high reflectivity for visible light and high transmittance for near-infrared light.Hot reflectors can reduce heat and lower the thermal impact on the overall perfor- mance of systems.
