Wedge prism

Bulk supply wedge prism, prism lens

It is a small Angle deflection element in an optical system. When two identical optical wedges are used together, any optical wedge is rotated separately, and the outgoing light can change in any direction in the Angle cone with incident light as the axis. The formula to determine the deviation Angle is: θd = arcsin(nsinθw) -θ w where θd is the Angle of ray deviation, θw is the Angle of optical wedge, and N is the refractive index corresponding to the wavelength used.

Mainly used in: CD, DVD, BDDVD laser reading head light path reflection, reentry bias.

Tir prism, is 2 pieces of triangular prism, generally a prism oblique

The side IS FULLY INVERTED (THE ILLUMINATION BEAM IS FULLY INVERTED), which is used to separate/change the number

Light paths, illumination beams and imaging beams in the word projection system.

Using DLPTM technology, usually applied in the system.

Advantages:

1. The air gap above the useful area is consistent;

2, good geometric size and surface flatness;

3, high transmission rate in the range of visible light;

4, coating reliability;

5. Easy system assembly;

6, stable and strong structure;

7. Allow miniaturization.

Definition of prism and rectangular prism:

Prism is a transparent polyhedron enclosed by two intersecting but not parallel planes, used to change the path of light or make the beam of light dispersive, made of transparent materials such as glass, crystal, etc.

A rectangular prism is a rectangular triangular prism, that is, a prism with right triangles above and below. The optical path can be deflected by 90° or 180°, depending on which side of the prism is used as the incident surface. See the prism
