Beam Mirror
The beam combiner produced and developed by Beijing Jingyi Bodian Optical Technology Co., Ltd. is made of zinc selenide, zinc selenide or germanium and coated with an optimized thin film. Its function is to transmit and reflect light of two wavelengths respectively. combined into one optical path. The beam combiner transmits light of one wavelength and reflects light of another wavelength (usually visible light) at the same time. It can combine two beams (or multiple beams) of light of different wavelengths, and use one of the beams of reflected visible light to calibrate The other invisible light beam combiner usually transmits infrared light and reflects visible light. It is widely used in various laser industries. Generally, it combines the processing laser and the wavelength light used for imaging or indication into one beam and the working position. It is designed to transmit part of the wavelengths of different bands and reflect part of them. Jingyi Bodian can provide customized product size, transmission wavelength, reflection wavelength and incident angle and other services.

Neutral Density Sheet
The Neutral Density Filter is a high transmittance, low dispersion glass made from a soda lime silicate material. The neutral density filter produced and developed by Beijing Jingyi Bo Electro-Optical Technology Co., Ltd. has the characteristics of high transmission efficiency, wide range of low-color applications, etc., and this material also has good nonlinear properties – when Its refractive index and scattering coefficient increase when the temperature increases; in addition, there is a higher dielectric constant and a lower dielectric loss factor. These factors combine to make the material’s nonlinear properties outstanding. The commonly used types of neutral density filters are double-layer double-silver hollow fiber filters with single-sided silver plating, double-sided double-silver filters with hollow fiber and aluminum foil, and double-sided gold-plated hollow fiber filters.

Solar Simulator Interference Filters
With the wide application of solar simulation technology in different fields, solar simulator filters are bound to develop rapidly. At present, the cost of optical filters produced by many foreign manufacturers is too high, and the unit price is basically around 1,000 US dollars. The quality of optical filters directly determines the performance of simulated sunlight. Some manufacturers use a piece of insulating glass instead of a filter, and the performance obtained is far from the standard value. This kind of filter must be realized by coating in order to have a better effect. The solar simulator filter produced and developed by Beijing Jingyi Bodian Optical Technology Co., Ltd. is low in cost. The filter has high temperature resistance, high spectral matching, and adopts multi-layer hard film ion-assisted deposition technology. Nanomaterials are evaporated in high vacuum. The film layer has good compactness, and has reached the international advanced level after direct testing by many manufacturers, and has been successfully applied to various solar simulators.
