Here we just describe a design method and result for an infrared system. This optical system can be used in the dual band infrared and also can be used at visible wavelengths. The design is based on an off-axis three-mirror anastigmatic (TMA) system. The off-axis concept allows wide-field enabling a variety of observations designs for the Multi-Object Spectrometer instrument optimized for low scattered light and low emissivity. The large field of views available: 30 degrees in the IR and the visible, and the system large aperture is F/2.5-F/2. The final optical system is a three-mirror unobscured telescope with two off-axis segments. It achieves diffraction-limited imagery at visible and IR wavelengths. Achievements of computer technology of automated shaping of large-sized optical details with achieving of diffraction quality of the image permit to expand technological opportunities of the method on creation of aspherical off-axis mirrors of a complex configuration. Technical parameters of made off-axis aspherical mirrors are listed.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
