A prism is a polyhedron made of transparent materials such as glass, crystal, etc. It is widely used in Optical instrument. Prisms can be divided into several types based on their properties and uses.

Now, the application of infrared optical lens has become more and more popular. Our infrared lenses mainly include ZnS Zinc sulfide lens, CaF₂ Calcium fluoride lens, BaF₂ Barium

Zinc sulfide lens is an optical lens made of Zinc sulfide material, which is commonly used in infrared optical systems.

Focal length is an important concept in optics, used to describe the optical characteristics of a lens or mirror.

A fully reflective mirror is an optical element used to achieve complete reflection of light. In an ideal situation, a fully reflective mirror can achieve the reflection of light, that is, all inciden

The light rays entering the diverging lens parallel to its axis diverge, and all rays seem to originate from its focal point F. But the dashed line is not a light, but rather indicates the direction i

Aspheric lenses are used to eliminate spherical aberration in various applications, including barcode scanning, laser diode collimation, or OEM or R&D integration.

When light travels in the air and encounters different media, its propagation direction will be changed due to the different refractive indices of the media.

Cylindrical mirrors are commonly used to change the shape of light sources in optical systems, making them linear light sources. Cylindrical mirrors can be used for correcting astigmatism in the syste

In the optical assembly industry, reducing the number of lenses is the first factor to consider in design, and choosing a single lens is a good solution.

The use of aspheric optical devices is mainly due to their advantages over spherical optical devices. The biggest advantage is the correction of aberrations and the related better imaging characterist

Aspheric lenses can improve image quality and correct imaging problems typically associated with spherical lenses. The original work and functions of aspherical lenses are mainly reflected in the foll
