Why Choose a Grating Over a Prism? - Linear(ish) wavelength dispersion (easier calibration) - Higher resolution in compact form factor - Customizable efficiency peaks and order selection - Works across broad spectral ranges with right coating/material
- No coating degradation on the reflecting surface (TIR mode) - Easier to mount and align – self-locating 90° geometry - Lower wavefront distortion under vibration or temperature drift - Compact footprint for tight optical layouts
Changchun Realpoo provides customized optical solutions for different laser line generation applications. The following table lists typical specification ranges for reference. Actual parameters depend on the optical design and manufacturing requirements.
A Powell prism is an optical component designed to convert a laser spot into a straight laser line with a more uniform intensity distribution. It is particularly useful when consistent brightness along the entire laser line is essential for accurate measurement, inspection, or positioning. Compared with a conventional cylindrical lens, a Powell prism redistributes laser energy from the center tow
Our Powell prisms are manufactured with advanced optical processing technology, ensuring excellent surface quality, accurate fan angles, and stable optical performance. They are widely used in 3D scanning, machine vision, laser measurement, alignment systems, medical equipment, and industrial inspection applications.
