Welcome

Where the 19th Century Art of Mirror Making Meets the 21st Century

The Saint Petersburg Mirror Lab is a small band of dedicated mirror grinders and telescope makers living in the Tampa Bay area of Florida. We offer a mirror making class for interested persons. We strive to create the best mirrors our home brew technology can muster. This includes robotic foucault testing and laser interferometry.

parabolize the mirror. By keeping the mirror on the bottom it remains fully supported and flat.

  Carlos Paris visitor from Ft. Myers
2012-06-10
Carlos Paris was a visitor from the Ft. Myers area and needed help with his 6" mirror. He has
been working alone on it using an impessive home-made Foucault tester and a couple of good books.
Now he was ready to start figuring it. He finished it at the lab better than 1/9th wave during
his first visit (also 6/2).
