Product Case Studies

A pyramid prism consists of three mutually perpendicular reflecting surfaces, forming a pyramid shaped structure with an internal angle of 90 degrees. When light is incident on any reflective surface, it undergoes three reflections and ultimately leaves the prism in a direction almost completely opposite to the incident light. This triple reflection ensures that the direction of the reflected light is highly consistent with the direction of the incident light, achieving precise retroreflection of the light even if the incident angle changes.

characteristic

• High reflection efficiency：A pyramid prism can reflect the majority of incident light back to its original direction, providing high reflection efficiency.
• Directional stability：Due to its unique geometric structure, the direction of reflected light is almost the same as the direction of incident light, making corner prisms very useful in applications that require high directional stability.
• Wide band applicability：A pyramid prism can be used for multiple wavelengths of light and is suitable for wideband applications.
• Structural stability：Due to its simple and sturdy structure, corner prisms are suitable for use in harsh environments.

application

1. laser ranging：In a laser rangefinder, a conical prism is used to reflect the ranging laser to measure the distance to the target.
2. Optical Communication：In optical communication systems, corner prisms are used to ensure that signal beams propagate along a fixed path, improving signal stability and accuracy.
3. scientific research：In experiments in fields such as physics and astronomy, corner prisms are used to achieve precise beam control and reflection.
4. Navigation and positioning：In some special navigation and positioning systems, corner prisms are used as passive reflectors to reflect signal light and assist in positioning.

advantage

• Provide a very stable reflected light path, suitable for applications that require high-precision beam control.
• The structure is simple and sturdy, suitable for use in various environments.
• Suitable for wideband applications and compatible with multiple light sources.

disadvantage

• Compared to other types of reflective prisms, corner prisms may be heavier and more expensive.
• In some extreme application scenarios, additional optical processing may be required to optimize performance.

Angular prisms play an important role in various optical systems through their unique design and excellent optical performance, especially in applications that require extremely high beam direction stability and reflection efficiency.
