The optical system is not coated, and due to interface reflection, the transmitted light energy is very weak, reducing the imaging quality and resolution of

A filter is an optical element used to select the desired radiation band, which absorbs certain wavelengths, making the object darker. These are flat glass

Concave and convex lenses can be further subdivided into many different types, including spherical lenses with circular surfaces, aspherical lenses with curved but aspherical surfaces,

Prisms are solid glass optics that are sanded and polished to form geometrically and optically distinct shapes. Angle, position, and optical flat crystal count help

With the continuous progress of modern science and technology, glass has also been applied in different industries. According to different properties of glass, it is

Precision optical flat glass is a fused quartz optical component that can be used as a reference to determine the flatness of unknown surfaces. For

The edge of the filter is engraved with an arrow to indicate the recommended direction of the light transmission filter. Although any side of the

The main materials of prisms are BAK4 and BK7. The refractive indices of these two types of glass are different. BAK4 has a high refractive

There are many types of filters for tubes, but they all have the same basic function – transmitting light of a specific wavelength or color

A pentagonal prism can accurately deviate the line of sight or input beam by 90 ° (± 30 angular second accuracy). In imaging applications, pentagonal
