Beschreibung
Zusammenfassung:	The present invention relates to a confocal type Raman cell, and it is characterized by that the input window and output window of the Raman cell are formed from the incident lens and exit lens which are respectively and directly mounted on two ends of said Raman cell, the described incident lens and exit lens are concave-convex lens made up by uisng concave face and convex face with different curvature radiuses, its concave face is retatively formed into confocal system, and the concave face of the described incident lens is coated with two-color film which has high transmission coefficient for pumping light wavelength and total reflection coefficient for Raman light wavelength, and the concave face of the described exit lens is coated with two-color film which has high reflection coefficient for pumping light wavelength and anti-reflection power for Raman light wavelength.
