Optical filters are used to “attenuate or enhance the image.”. Optical filters can also reflect unique wavelengths, dividing images into two identical images or transmitting

Spherical lenses achieve different imaging purposes by changing the spherical radius of the lens, which is difficult to process when the focal length is too

In order to eliminate the polarization effect caused by oblique incidence of light, a design method of depolarizing prism based on Brewster condition is introduced.

We can provide a large number of customized infrared IR lenses and components for focusing, collimating, and collecting light in the Near Infrared (NIR), Short

Flat concave lens: One side is concave and the other side is planar, with a negative focal length. Typically used for beam collimation, increasing (decreasing)

A pentagonal prism is a pentagonal prism with four polished surfaces, two of which are reflective surfaces, and the other two are incident and outgoing

Dowell prism has a very unique performance – if you observe through the prism and rotate around the longitudinal axis, the resulting image rotation angle

What is a pyramid prism? The pyramid prism, also known as the Paul prism, is an optical element used in optical instruments and is a

Achromatic lenses (glued lenses) are used to minimize or avoid chromatic aberration. Its achromatic design also helps to minimize spherical aberration. Achromatic lenses are suitable

Roof Prisms is commonly used in extremely compact binoculars because of its small size and the ability to align the objective lens and eyepiece in
