Visible Dome

 BRD Optical transparent optical glass dome lens is composed of two parallel optical surfaces, (A convex surface & A Concave surface). Normally we can control the parallel tolerance <±2μm. A perfect parallel surface, in the imaging, the image does not distort, and in the measurement of light, the light does not distort. BRD Optical Dome, the optical properties are unique, which produced by the optical technology of optical grinding and polishing.

 

BRD Optical large clear dome lens mainly are hemisphere, hyper-hemisphere, and customized designing. Whether it is a visible dome, UV dome, or IR dome, BRD Dome has been confirmed in the international market. BRD dome is found in areas such as defense technology, weather monitoring, and optical imaging.

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 an...
