Introduction of TIR Prism/Totally Reflecting Prism

TIR prisms, also known as total reflection prisms, are usually made of optical glass, crystal, or other transparent materials. They are made of a combination of two triangular prisms, usually one prism with a beveled edge that undergoes total reflection (TIR), and are used to separate or change the path of the light in digital projection systems, such as the illumination beam and the imaging beam. This structure allows the TIR prism to effectively control the direction of light propagation and to realize functions such as deflection or focusing of light.

I. Principle of operation

TIR prism (total reflection prism) cross-section is usually isosceles right-angle triangle, when the light shoots perpendicularly to a right-angle surface of the prism, the light will be shot into the prism in the original direction and total reflection occurs on another right-angle surface, thus changing the direction of propagation of the light, and this total reflection process can effectively reduce the loss of light, and improve the efficiency of the use of light energy.

II. Performance Characteristics

High integration efficiency: TIR prisms can effectively concentrate and transmit light and improve the utilization of light energy.

Small light collecting area: Due to the special design of the prism, it can realize high efficient optical performance in a small area.

High light energy utilization: Due to the characteristics of total internal reflection, TIR prisms are able to reduce the loss of light energy and increase the efficiency of light energy utilization.

Good uniformity: TIR prisms provide a uniform distribution of light, allowing the light to maintain a stable brightness during transmission.

Less light loss: Due to the reduction of light refraction and scattering, TIR prisms can reduce light loss and ensure the quality of light transmission.

III. Application Fields

Optical display field

Laser TV: TIR prisms can enhance the color purity and brightness of laser TVs to meet consumer demand for large-size, high-definition TVs with good eye protection. With the continuous expansion of the laser TV market, the application of TIR prisms is also growing.

Periscope Camera: In mobile devices such as smartphones, periscope cameras utilize TIR prisms to change the optical path and achieve telephoto shooting, meeting the diversified needs of users for photographic functions.

Medical endoscopes: The high integration efficiency and high light energy utilization of TIR prisms have led to their application in medical endoscopes and other medical instruments, providing doctors with clearer and more accurate medical images.

Optical Communication

TIR prisms are used in optical communication systems for transmission and conversion of optical signals, and their high efficiency of light energy utilization and uniformity ensure the stability and reliability of optical signals in the transmission process. With the continuous development of optical communication technology, the application of TIR prisms in this field will continue to expand.


Measuring instruments and optical equipment

TIR prisms are widely used in cameras, projectors, telescopes, microscopes, leveling instruments and other optical equipment to change the optical path, focusing, etc., which improves the performance and accuracy of these devices.


Solar Converters

In solar energy conversion systems, TIR prisms are able to concentrate and transmit sunlight efficiently, improve the conversion efficiency of solar energy, and provide strong support for the utilization of solar energy.

Medical Instruments and Laser Therapy Devices

TIR prisms are used in medical instruments and laser therapy equipment to control the direction and intensity of laser beams and realize precise treatment, contributing to the development of the medical field.

Other Fields

TIR prisms also have applications in fingerprint identification, cloud observation, and other fields. For example, in meteorological observation, TIR prisms can be used to observe the nature of the shape of cloud layers and changes in airflow and wind speed and direction.
