Broad-spectrum imaging spectrometer based on transmission and reflection integrated structure

A broad-spectrum imaging spectrometer based on reflection and transmission integrated structure, comprising a coaxial reflection outer cylinder configured to reflect an optical path and a coaxial transmission outer cylinder configured to transmit an optical path, wherein a slit component is provided at an incident end of the coaxial reflection outer cylinder to collect incident light;

• a spherical mirror and a plane mirror are provided above the slit component;
• the incident light passes through the plane mirror and undergoes a first reflection by the spherical mirror, and the plane mirror performs a second reflection of the light from the first reflection and directs the light into the coaxial transmission outer cylinder for transmission;
• and
• a grating prism module and a focusing inner cylinder are provided within the coaxial transmission outer cylinder along a transmission direction, a cemented lens module is provided in the focusing inner cylinder, and a terminal end of the outer cylinder connects to an imaging mechanism with an embedded detector chip and detector imaging surface;
• the cemented lens module is fixedly provided inside the focusing inner cylinder, the focusing inner cylinder is placed within an adjustment chamber of the coaxial transmission outer cylinder, and a width of the adjustment chamber is greater than a width of the focusing inner cylinder, facilitating changes in the distance between the cemented lens module and the grating prism module and the detector chip.
