The optical property measurement technology plays very important role in the field such as bomb-guide, anti-bomb space target-detection and target identification. The ground-based optical measurement equipment has the advan- tages such as large optical caliber and advanced detecting technology, and it is very important in the optical property meas- urement system. In the project of developing a certain model ground-based optical property measuring system, according to the index requirements, a primary optical system with Ф1 000 mm caliber is used to receive. By three-level light spectrum, on the basis of using primary optical system, the system can fulfill the detection functions of visible light, SWIR, MWIR and LWIR, and it can perform these detection tasks for four waves simultaneously. The experiments indicate that this optical sys- tem has good imaging quality, the mechanical structure is compact, and it satisfies the requirements of the design index.
