Industrial optics - Primary tested + 35mm Secondary


The industrially manufactured primary mirror is tested with interferometer to guarantee optical surface quality. Surface defects are measured and documented. Note: only the primary mirror is tested.
Industrial optics: 150mm f/5 parabolic primary mirror + 35mm secondary mirror. The primary offers an ideal ratio for deep sky observation with aluminized surface.
The primary mirror is delivered with its bevel mask to protect the edges during assembly in the Smallest telescope.
Dimensions and specifications of both mirrors optimized for perfect integration into the Smallest telescope.
