99% :1% beam splitter

Brief description of beam splitter:

1. From the perspective of users: beam splitter is also called beam splitter Optical coating manufacturers call this product spectroscopic film;

2. Classification from coating method and process: all dielectric spectrograph (made of Ta2O5 and SiO2 materials by cross vacuum coating) The other is the metal plus dielectric spectroscope, also known as the attenuation plate, because it only considers the transmission ratio column and the reflected light is not taken as the reference focus. Generally, chromium or nickel chromium alloy plus plating medium or diamond film is used to enhance its firmness and not be affected by environmental damage

3. Classification from incident angle and polarization state: non flat polarization and P, S polarized light splitter to be considered

4. Classification from glass material and appearance: plane beam splitter, prism beam splitter and lens beam splitter

5. Classification from light source and used wavelength: single wavelength splitting and multi wavelength (wide wavelength) splitting

6. Classification from the region of the wavelength used: ultraviolet spectroscopy, visible spectroscopy, near infrared spectroscopy

7. The larger the spectral ratio of the dielectric spectral film, the smaller the spectral value error and the greater the difficulty of plating The conventional spectral ratios are: 99:1, 98:2, 95:5, 90:10, 80:20, 70:30, 60:40, 50:50

8. The higher the reflectivity of the spectroscopic film, the more difficult it is to produce or the spectroscopic value tends to be the smallest, and the more difficult it is to plating

9. Application fields of spectrophotometer: UV detection or production equipment, general optical instruments, fingerprint biological detector, digital imaging instrument, laser control system, optical communication instrument
