Roof prisms also called amici prisms or right angle roof prisms, do two things: invert the image and bend the line of sight through a 90° angle.They are excellent as prism diagonals in optical sys

Spherical mirror is extensively applied in daily used, for example, cosmetic, decoration, streets, garages, buildings, security, automotive and astronomy and so on.We will also do according to the spe

Plane parallel windows are widely used as transfer optics and shields. Optical windows are used to separeate two different enwironments while still allowing light to pass through.Optics windows can be

achromatic lenses  can be used to collimate and focus laser beams. They can also be used for high-quality imaging on-axis. It alsocan eliminate spherical aberration and reduce other optical aberratio

Ball lenses have an even higher index of refraction, providing a shorter back focal length, which simplifies fiber coupling.Other uses include endoscopy, bar code scanning, ball pre-forms for aspheric

When a light beam is incident onto a surface inclined at an angle of incidence to the incoming beam, the reflected and transmitted light becomes partially polarised. This can be resolved into two comp

Bi-Concave Cylindrical LensesWe will also do according to the specifications such as size, structure, material, surface treatment and so on that the customers required. We supply them with good qualit
