Astronomical Telescope Mirror
Astronomical mirrors are concave optics, generally with glass-ceramic or borosilicate substrates and high-reflectance aluminum or silver coatings plus protective layers. They collect celestial light by reflection rather than lens refraction. The described image shows a Cassegrain primary mirror with a central through-hole for light reflected from the secondary. Nanometer-level surface-figure error and low-expansion substrates reduce thermal deformation for sharp imaging. Blackened edges suppress stray light. They are widely used in reflective astronomical optical systems.
