The ground test model of a high-resolution camera for small satellites was developed. It is a Cassegrain system with field correction lenses. Except for lenses, all optical and structural components are made of the same Aluminum material. This scheme has its advantages in cost, development period, and athermalization. In addition, the deformation of mirrors occurred during assembly could be corrected by using simple clamps. After assembly, the final MTF was measured about 19%. The Aluminum-based test model was found to be a cost-effective tool for ground test.
