  ： ۲）Half mirror (splitter) product description

The Half mirror (splitter) is an optical window with a semi-transparent mirror-like film coated on the surface, which can split a beam of light into two or more beams. The beam splitter reflects part of the incident light energy, absorbs a relatively small part, and transmits the rest of the energy. The beam splitter has obvious neutral color characteristics. The beam splitter is made by vacuum evaporation of a multilayer dielectric film. There is no problem of absorption by the metal film. The total penetration and reflection ratio is close to ۱۰۰.

Manufactured by vacuum evaporation method, after the light passes through the filter, the penetration ratio can be changed, for example: half penetration and half reflection, with low absorption characteristics.

Optical coating (antireflection coating, high reflection coating, spectroscopic coating)

： Product Features

The optical coating is a process of attaching the medium to the surface of the element to achieve more functions of the lens. It can provide the processing of anti-reflection film, high-reflection film, spectroscopic film, band-pass film and other film systems.

Anti-reflection coating is the most widely used optical film in optical components, mainly to make almost all light of a certain wavelength or a certain wavelength range pass through the lens. There are several film systems such as single-wavelength anti-reflection coating, broadband anti-reflection coating, and dual-wavelength anti-reflection coating.

Aspheric lens (including UV fused silica cone, optical collimating lens, aspheric lens)

： Description

The aspheric lens adopts a single element design, which helps to reduce the number of lenses in a multi-lens optical assembly. In other words, unlike a conventional lens with a spherical shape, an aspheric lens has a more complicated surface that continuously changes from the center of the lens to the curvature l of the lens edge. The reduction in the total number of components not only helps reduce the size or weight of the system, but also simplifies the assembly process.

： Product Advantage

The most significant advantage is that it can correct the spherical aberration caused by the spherical lens in the collimation and focusing system. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate the spherical aberration to the greatest extent. Aspheric lens (light converges to the same point to provide optical quality), basically eliminating the spherical aberration (light converges to different points, resulting in blurred imaging).

The aspheric lens can image in the range of ۰.۸-۱۲um, and is not disturbed by weather changes and light conditions. The image is stable, the image quality is clear, and the aberration is small.
