Meniscus Lens

BRD Optical provides meniscus lens in both positive and negative focal lengths. These lenses are useful when used with another lenses to increase or decrease the focal length. This lens element configuration does not introduce any additional coma or spherical aberrations


Description Of Positive/Negative Meniscus Lens

BRD Optical provides meniscus lens in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.

  Introduction Of Optical Application Optical engineering is a long and young subject. Its theoretical basis-optics, as the backbone of physics, has experienced a long and tortuous development path, casting geometric optics, wave optics, quantum optics and nonlinear optics, revealing the law of light generation and propagation and the relationship with matter Interaction relationship. With the rise of laser technology and optoelectronic technology, optical engineering has developed to be based on precision optical products, and is integrated with disciplines such as information science, energy science, material science, life science, space science, precision machinery and manufacturing, computer science, and microelectronics technology. Closely intersecting and interpenetrating disciplines. It contains many important emerging disciplines, such as laser technology, optical communication, optical storage and recording, optical information processing, photoelectric display, holography...

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...
