Polarizing beam splitter prism
The polarizing beam splitter prism is an optical element which is formed by plating a multilayer film structure on the inclined surface of a right-angle prism, and then gluing to form a cubic structure. By utilizing the property that the transmittance of P polarized light is 1 and the transmittance of S polarized light is less than 1 when light is incident at Brewster angle, after the light passes through the multilayer film structure for many times at Brewster angle, the obtained P polarized component is completely transmitted, and most of the S polarized component is reflected (at least more than 90%).
The polarizing beam splitter prism is used to separate the horizontal polarization and vertical polarization of a beam of light, the transmittance ratio of P light to S light is more than 1000, and the transmittance of P light is ensured to be more than 90%. It has the characteristics of small stress, high extinction ratio, good imaging quality and small beam deflection angle. The wavelength covers 420-1600nm. It can be used for polarization, polarization detection, light intensity adjustment and other occasions.
It should be noted that the working effect of polarizing beam splitter prism is limited by wavelength. In addition, the polarization splitting prism is only an element for roughly selecting polarization, and if the purity requirement for polarization is very high, the Glenthompson prism can be used.
Triangular Prism
In geometry, a triangular prism is a three-sided prism; it is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides. A right triangular prism has rectangular sides, otherwise it is oblique. A uniform triangular prism is a right triangular prism with equilateral bases, and square sides.
Equivalently, it is a polyhedron of which two faces are parallel, while the surface normals of the other three are in the same plane (which is not necessarily parallel to the base planes). These three faces are parallelograms. All cross-sections parallel to the base faces are the same triangle.
Right angle prism
A right angle prism is often used as a reflector, which can turn the optical path 90 degrees. After total internal reflection, it can also be used as an image retroreflector, which can turn light 180 degrees.
- Efficient rotation of broadband light beam
- Rotate beam 90 or 180
- The molten Shi Ying mold can be transported to 220nm
90 rotation: 90 rotation occurs on an inclined plane. Imaging is upright or upside down
180 rotation
180 rotation takes the inclined plane as the entrance surface and the exit surface. When the plane of incident light contains vertices, it is mainly used as an image retroreflector.
