BROAD-SPECTRUM IMAGING SPECTROMETER BASED ON TRANSMISSION AND REFLECTION INTEGRATED STRUCTURE

Disclosed is a broad-spectrum imaging spectrometer based on reflection and transmission integrated structure, including a coaxial reflection outer cylinder and a coaxial transmission outer cylinder. A slit component is provided at an incident end of the coaxial reflection outer cylinder; a spherical mirror and a plane mirror are provided above the slit component; incident light passes through the plane mirror, reflects off the spherical mirror, and is further reflected by the plane mirror into the coaxial transmission outer cylinder; a grating prism module and a focusing inner cylinder are provided within the coaxial transmission outer cylinder along a transmission direction, and a cemented lens module is provided in the focusing inner cylinder; the cemented lens module is fixedly provided inside the focusing inner cylinder, the focus inner cylinder is placed within an adjustment chamber of the coaxial transmission outer cylinder.
