Light path reflection device

The utility model provides a light path reflection device which is characterized in that the light path reflection device comprises an incident port, an emergent port and four inclined reflectors, light entering from the incident port is reflected to a second reflector after entering a first reflector, is reflected to a third reflector after being reflected by the second reflector, is reflected to a fourth reflector after being reflected by the third reflector, and is reflected to a fourth reflector after being reflected by the fourth reflector. And the light is reflected by the fourth reflector and then emitted from the exit port. According to the light path reflection device, the reflection times are increased through the four reflectors, and the purity of spectrums of specific wavebands is ensured. The whole device is simple in structure, low in cost and easy to machine. 本实用新型提出一种光路反射装置，其特征在于，包括入射口、出射口及四个倾斜的反光镜，入射口进入的光入射到第一反射镜后反射到第二反射镜，经第二反射镜反射后反射到第三反射镜，进而经第三反射镜反射后反射到第四反射镜，经第四反射镜反射后从出射口发出。本实用新型光路反射装置通过四面反射
