Dove Prisms

The Dove prism is used as a reflection prism to invert the image and is used in the parallel light path based on the critical angle principle to meet the total internal reflection of the limited FOV. Tianyanggu Daowei prism processing technology is mature and easy to achieve high precision. The precision of prisms with a diameter of less than 3 inches can be controlled within 2 seconds. The roof prism is processed through milling, fine grinding, grinding and polishing processes to achieve high-precision mirror flatness and included angle accuracy.

Features of Dove Prisms

Features of Dove Prisms
  • One-stop customized production: Solar Valley processes Dove prisms of various sizes and shapes according to customer requirements.

  • Material: Made of optical glass and optical quartz.

  • Dove prism properties: A light beam entering one inclined plane of the Dove prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite inclined plane. The image passing through the prism is inverted, and since only one reflection occurs, the image is inverted but not laterally transposed. A beam entering the inclined surface undergoes total internal reflection from the bottom surface and emerges from the opposite inclined surface. It can be used in the following interferometry, astronomy, etc. The uncoated Dove prism is mainly used for image rotation in the optical-mechanical system. It can rotate the image 180 degrees; the coated Dove prism is mainly used to coat the reflective surface with aluminum for reflection. Film, coated with anti-reflection coating on the incident surface, used in imaging systems.

  • Description of product size indicators: Maximum dimensions of Dove prism: ≤100×100mm Thickness T≤50mm

  • Surface defect grade: 60-40, 40-20, 20-10, 10-5. Produced according to customer requirements.

  • Coating: Coating according to customer requirements.
