Noni offers custom powell prism service. A Powell Prism is an optical scribing prism that consists of two intersecting right-angle prisms that produce a 90-degree turn in the optical path. Powell prisms are commonly used in the fields of optical measurement, optical testing and laser technology. Depending on the specific application scenario, Powell prisms can be customized with different specifications and materials, such as fused silica and K9 glass. They have a simple shape and structure, reasonable optical path design, and good optical performance and stability. Powell prisms are capable of refracting the incident beam at an angle of 90 degrees to the normal direction without affecting the focusing characteristics of the beam. This type of prism is especially suitable for applications where the beam needs to be steered with little effect on the beam itself.
