45 degree 25.4*5mm R/T=50/50 @1064nm Spectroscope Quartz laser mirror

Description:

It is an optical device that can divide a beam of light into multiple beams. It is usually coated with optical glass.

classification:

1.Cuboid

The cube beam splitter is composed of two 45 ° right angle prism. The beam splits on the prism slope (the inclined plane after coating or special treatment is half transparent).

2.Plane type

lanar beam splitter, thin plate half lens with uniform (equal or linear) thickness (one side of which is coated or specially treated to be semi transparent)

3.Nonpolarization type

In the nonpolarization type, the incident beam partially reflects on the semi transparent surface and partially transmits to form two beams of light. Only the light intensity of the light source is separated according to the proportion of the semi transparent surface (transmittance: reflectivity). The other properties of the light source are the same as the incident light except for the light intensity. Most of them are plane type)

4.Polarization beam splitter

In polarization mode, the incident beam is on the semi transparent surface, which is composed of several layers of polarizers. After several times of reflection and reflection, the incident beam is separated according to the polarization phase. The intensity of the light source is separated according to the ratio (transmission polarization angle range: reflection polarization angle range). The polarization state of the two separated beams is different except for the light intensity. Most of them are cubic.

Application:

Beam splitter is widely used in teaching interferometer, laser interferometer, polarized light research, optical fiber communication and other optical research and application occasions. It is an important component of optical research and use system.
