Thorlabs Shear Plate Interferometer

Thorlabs Shear Plate Interferometer – This optical diagnostic tool is designed for laser beam collimation and wavefront analysis. The shear plate interferometer works by creating interference fringes that indicate the degree of collimation of a laser beam. The model shown is suitable for beam diameters between 2.5 mm and 5.0 mm. Constructed with precision optics and a durable housing, it is commonly used in research laboratories, optical alignment setups, and laser maintenance applications. The interferometer provides a quick and reliable way to assess laser quality without requiring complex alignment procedures.
