Custom-coated Hollow Corner Pyramid Reflectors

Custom-coated Hollow Pyramid Retroreflector Prism

Pyramid Prisms, also known as Paul prisms, are isosceles right-angled prisms made of glass with the end face facing the right angle.

Light enters from a large rectangular surface and exits from the original incident surface after two total reflections from the inclined plane, which has no dispersion effect, but flips the image 180° and returns in the original direction.

Custom-coated Hollow Corner Pyramid Reflectors

 

The hollow retroreflector is a specialized optical component consisting of three mutually perpendicular reflective surfaces, designed to return incident light precisely along its original path (i.e., retroreflection). 

Retroreflection Principle

  • Regardless of the incident angle (within the acceptance aperture), reflected light returns exactly parallel to the input path (deviation <5 arcseconds).

 

WTS could make customized Pyramid prisms with different material, different size.
