Semi-transparent and semi-reflective mirror
A semi transparent and semi reflective mirror, also known as a beam splitter, beam splitter, or semi reflective lens. It is an optical component that is coated with a semi reflective film on optical glass to change the ratio of transmission and reflection of the incident light beam. Coating can increase transparency, increase light intensity, and also increase reflection, reducing light intensity. And semi reflective and semi transparent means that the transmittance and reflectance of this film are each 50%. When light passes through this film, the transmitted light intensity and the reflected light intensity each account for 50%! It selects the required reflectivity according to specific needs, which can be relatively low or high, collectively referred to as "ldquo; Half reflective and half transparent;. Half transparent and half reflective lenses have the characteristic of low absorption.
At present, there is a great demand for the use of visible light semi reflective mirrors in some precision optical instrument fields, usually requiring a visible light transmittance of 45% to 70%. The wavelength range of visible light is 380nm to 780nm, and its transmittance should gradually increase. However, existing visible light semi transparent and semi reflective glasses have unstable transmittance effects, with similar transmittance across all visible wavelengths. It is becoming increasingly difficult to meet the transmittance requirements of precision optical instruments. Only coated semi reflective mirrors can meet the requirements. In addition, semi transparent and semi reflective mirrors are also used in machine vision and coaxial light source systems to partially split specific light, and the split light path is used as an induction chip as a feedback signal to adjust the stability of laser power output and ensure the normal operation of machine vision.
Production process:
The manufacturing process of visible light semi permeable semi reflective mirror includes placing a transparent glass substrate in a precision vacuum coating machine, setting the film thickness parameters, and finally forming 18 layers of coating through vacuum coating. After coating, the transmittance of the semi transparent mirror ranges from 45% to 70% in the visible light band of 380-780nm, and the transmittance of the semi transparent mirror steadily increases from 380-780nm. Can meet the transparency requirements of precision optical instruments for visible light semi transparent and semi reflective.
Semi reflective and semi transparent lenses have great application space due to their excellent optical transmission and reflection properties. They are widely used in fields such as machine vision, optical equipment, photography lenses, car rearview mirrors and electronic product displays, phantom imaging display cabinets, exhibition stands, broadcasting teleprompters, full projection screens, and semi transparent and semi reflective screens. Ruicheng Optoelectronics produces semi reflective half lenses that can be customized with spectral ratios according to customer requirements, meeting the requirements of precision optical instruments.
