TS-Optics tested secondary mirror for Newtonian telescopes

The elliptical secondary mirror is intended for the construction and improvement of Newtonian telescopes. The mirror is coated with a 94% aluminium reflective layer, which is protected by a quartz layer. This makes the secondary mirror robust and resistant to aging.

Each secondary mirror is tested at Wellenform (Germany) and is provided with a test number. This number can be found on the packaging, on the back of the secondary mirror and of course on the certificate. This prevents any confusion.
