A spectroscope is a lens that allows part of the light to pass through and part of it to achieve the spectroscopic effect. A special film is coated on the surface so that the incident light can be reflected half and transmitted half, thus dividing a beam of light into a reflected beam and a transmitted beam, forming two beams of light. The spectroscope reflects part of the incident light energy, absorbs a relatively small amount, and transmits the rest of the energy. The spectroscope has a distinct neutral color characteristic. The spectroscope is made of multi-layer dielectric film vacuum evaporation, without the problem of metal film absorption, and the total ratio of penetration and reflection is close to 100.
