To meet the increasing demands of Inertial Confinement Fusion (ICF) shock velocity passive measurement, an optical collection system was designed. The 300—800 nm apochromatic optical system was designed using fluoride optical glasses, which have high transmission in the ultraviolet band. The imaging system has two lenses. The light beams between the two lenses were parallel, and the distance between the lenses could be varied to meet the size demands for different assembly positions. The machine visions on both sides of the first lens permit the system to achieve automatic homing. Five parallel laser beams were produced with one of them being on axis and lighting the target to obtain a clear image on the slit of the streak camera, and the other four surrounding the axis, lighting the second lens and focused on the imaging plane. The position of the separated optical elements present after the second lens can be easily fixed with the focusing lasers. The five laser beams can be terminated or turned on automatically. The first lens has an aperture of F/#4.0, and the collection system has a 10 μm object space resolution in 300—800 nm, and a 5 μm object space resolution in 532 nm. This optical system can passively measure the shock velocity by collecting the spectral radiance of the target. It can also act as the common path to transmit the probe laser and receive the Doppler-shift singles of VISAR simultaneously. This optical system could meet the demand of measuring the ICF shock velocity.
