Measure ultra violet and visible spectrophotometer wavelength indication error 's 90 corner light collector

The utility model relates to a measure ultra violet and visible spectrophotometer wavelength indication error's 90 corner light collector can effectively solve the arbitrary wavelength indication error 's of ultra violet and visible spectrophotometer measurement problem, and the technical scheme of its solution is, including reflection seat, base, convex lens and hollow connecting rod, the fixed dress of base is on the reflection seat, and open the lower part of base has into unthreaded hole, advances to be equipped with the upwards reflector of the reflection of light of inclined plane on the inherent reflection seat of unthreaded hole, and the anti - direction of light of reflector and dress are corresponding at the convex lens at base upper portion center, convex lens through the fixed dress of convex lens seat in the cavity at base center, the upper portion of convex lens seat is equipped with and is connected hollow connecting rod as an organic whole, hollow connecting rod is fixed to press the cap in.
