HR-250 Imager
Super-resolution Hr-250 Imager for Microsatellites
HR-250 satellite camera is high-resolution imager for microsatellites based on radiation-resistant optical components with very low coefficient of thermal expansion. HR-250 provides detailed earth imaging in panchromatic mode and has almost twice increased angular field of view without facing difficulties of "large" aperture technology and loss of spatial resolution. Designed a Cassegrain optical system with chromatic two-lenses corrector has a wide FOV as well as reduced decentering sensibility.
