Dual-channel imaging system for 1.2m telescope

The 1.2m telescope-based two-channel imaging system customized for KD is mainly composed of several groups of lenses and folding mirrors. It is an astronomical imaging instrument used with a 1.2m quantum telescope.

Wavelength coverage: 400nm-1000nm; the mean efficiency >99%; face form accuracy: <λ/10PV@632.8nm; face form accuracy after cementing <λ/40RMS@632.8nm;

The error of distance between the lenses is less than ±0.05mm, and the concentricity between the lenses is <±0.02mm; the total system mass is less than 80kg.
