High Precision Telescope Spectrograph Optics

Optical Surfaces Ltd. is a leading international supplier of high precision spectrograph optics for astronomical telescopes. Using a spectrograph enables researchers to study the chemical and physical conditions that exist through a cross-section of space. Combined with a land or space-based telescope a spectrograph can reveal valuable information from the spectral distribution of light from a distant astronomical object. Benefiting from a unique facility, where temperatures remain constant year-round and vibration ...
