Traditional spherical lens will produce spherical aberration.
Cassegrain telescope: a reflecting telescope composed of two mirrors, which was invented by Cassegrain in 1672.
Micro prism is primarily for the endoscopic, LD to fiber coupling applications.
Optical grade Czochralski silicon (OCZ-Si) as a transmission grade material is widely used in the mid-infrared (3-5um) band, and the infrared transmittance exceeds 50%.
For penta prism, the deviation angle of 90° is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled. We can supply high dimension and angle control penta prism.
Sapphire material has good light transmission performance. Therefore, lens products made of sapphire material have a longer service life and a wide range of adaptive spectra. Compared with optical glass, they have obvious advantages.
Calcium fluoride (CaF2) has a high transmittance from ultraviolet to mid infrared (250nm~7um), so it is widely used to manufacture prisms, windows and lenses.
Rod Lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod lens will be focused into a line. Optical glass and UV Fused Silica substrates are available for a variety of UV, Visible, and NIR applications.
Micro lenses, It can involve a variety of materials in the ultraviolet, visible, and infrared wavebands. Such microlenses are the core components of multiple optical systems and are widely used in medical instruments, optical fiber transmission equipment, micro imaging systems, and so on.
Meniscus lens is divided into positive and negative lunar lenses.One side of a meniscus lens is convex and the other side is concave.
