Application of half-wave plate and PBS in optical experiments
A half-wave plate is a birefringent element that can rotate the polarization direction of linearly polarized light by 90 degrees or 180 degrees.
The role of the filter
A filter is an optical device used to select a desired band of radiation. One of the commonalities of filters is that no filter can make the imaging of celestial objects brighter.
The principle and function of cylindrical mirror
Cylindrical mirror is a composite lens composed of a spherical surface and a cylindrical mirror surface. The spherical surface refers to the same radius of curvature in the horizontal direction and different radius of curvature in the vertical direction.
What is the role of the prism?
A prism is an optical instrument that is mainly used to separate and refract light. It is composed of transparent triangular prisms with wonderful optical properties
Application of spherical lens
Fiber coupling: Ball lenses are mainly used for coupling between optical fibers, between laser and optical fibers, and between optical fibers and detectors, or for the collimation of optical fiber beams in membrane filter dense wavelength division multiplexers.
