Problems solved by technology

[0009] The dichroic mirror method requires a specific dichroic filter and a complex optical system, which is expensive and difficult to adjust
The light source superposition method needs to collimate different light sources on the same axis. Usually, only about two kinds of light sources can be superimposed, and the spectral range is limited.

Abstract

The invention discloses a multiple light source light combination system based on integrating sphere spectral measurement. The system comprises a light source generation device, an imaging lens, a reflective mirror and an integrating sphere. Light rays emitted by the light source generation device reach the reflective mirror through the imaging lens and enter the integrating sphere through reflection of the reflective mirror. The system can carry out light combination of different light sources conveniently and rapidly, solves the problems of combination of any optical bands and continuous adjustment of light strength, and resolves the problem of lower output energy caused by insufficient light source power.

Description

technical field [0001] The invention relates to a measuring device, in particular to a multi-light source combined light system based on integrating sphere spectrum measurement, and belongs to the technical field of precision measurement. Background technique [0002] When performing transient measurements on the spectral characteristics of objects, the characteristics of the provided luminescent light source must be continuous full-wave bands, or spectra of certain specific bands, in order to obtain better stability and large dynamic range, and The light intensity signal intensity of each band is as close as possible, that is, the balanced light source of the whole band. [0003] When measuring traditional spectrum scanning spectrophotometers, due to the limitation of the radiation range of the light source, different light sources need to be replaced in the entire band, such as deuterium lamps when measuring 200nm to 400nm, and tungsten lamps when measuring 400nm to 780nm....
