Problems solved by technology

[0005] At present, some manufacturers of ultraviolet spectrophotometers only align the converter mounting parts with the lens mounting parts without connecting them. This method is not easy to ensure the alignment relationship between the photoelectric converter and the double-convex lens Ensure that the final formed spot matches the light-receiving area; there are also some UV spectrophotometer manufacturers who connect the converter mounting parts and lens mounting parts by bonding, such as image 3 As shown, the curved surface A of the converter mounting part 1 and the curved surface B of the lens mounting part 2 are bonded and locked. Although this bonding method is easy to ensure the alignment relationship between the photoelectric converter and the biconvex light-transmitting lens, due to the adhesive The converter mounting part 1 and lens mounting part 2 of the junction are inconvenient to disassemble, which brings inconvenience to the replacement of the biconvex condenser lens, and it is easy to damage the converter mounting part 1 and lens mounting part 2 due to the replacement of the biconvex condenser lens, resulting in The probability of secondary use of parts is greatly reduced, which brings inconvenience to users
