Quarter-wave plate

图片
  The 1/4 wave plate uses the anisotropic characteristics of the material to have different refractive indexes and propagation speeds for light in different polarization directions, resulting in a phase difference between the two components, and converting linearly polarized light into circularly polarized light, or converting circularly polarized light into linearly polarized light.   The 1/4 wave plate can realize the mutual conversion between linearly polarized light and circularly polarized light. Clever use of wave plates can also generate optical isolators, or simultaneously change the propagation direction and polarization direction of light.   The 1/4 wave plate can be applied to the laser. In the laser cavity, two quarter-wave plates placed on both sides of the gain medium can achieve single-frequency operation. A half-wave plate is placed between the laser crystal and the resonator mirror to reduce the depolarization loss. The combination of a half-wave plate and a polarizer

Polarization Beamsplitter Cube (PBS)

  Polarizing Cube Beamsplitters  Introduction Polarization beamsplitter cube  split randomly polarized beams into two orthog-onal, linearly, polarized components-S-polarized ligh is reflected at a 90°.   Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angleprism cemented together with a dielectric coating on the hypotenuse of one of prism.   The coatings have been designed to hold both the S-and P-polarization components to the same ratio of reflection-to-transmission over aspecific laser wavelength region.   This means that they will not change the state of polarization of the incident beam. The low polarization dependence of the metallic-dielec-tric coating allows the transmission and reflection for S-and P-polarization states to be within 6% of each other. All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating. We offer both broadband and single wavelength.   Standard

What is a Double Concave Lens?

图片
  1. Introduction to double concave lens A double concave lens is also called a negative spherical lens. The middle of the lens is thin, the edge is thick, and it is concave, so it is also called a concave lens, which has a divergent effect on light.   The imaging law of the concave lens is: when the object is a real object, it becomes an upright, reduced virtual image, and the image and the object are on the same side of the lens. The concave lens has a divergent effect on the light, so the lens is also called a divergent lens, a negative spherical lens.   2. Features of biconcave lens: A double concave lens is concave on both sides and has the same radius of curvature. A double concave lens with a negative focal length is usually used for beam collimation, increasing (decreasing) the focal length or enlarging (shrink) the image.   The double concave lens has a negative focal length and is often used in imaging or beam collimation applications. The coated lens is also widely used in v
