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.

Mike polishing towards a sphere

Mike is helping out during the polishing phase of his son's 8 inch mirror. There was a 500nm hill in the middle that he was cleaning up. By the end of the day the shape was a nice sphere and the laser test said that middle was polished. Once the polish works its way to the edge Scott will start figuring. (Photo by Scott) |

Lab staff 18th wave mirror
2013-08-05
|
| |
|
The mirror lab staff occasionally makes a mirror in our spare time. This 10" mirror, with final figuring by Ralph Craig, finished with a beautiful 18th wave figure. Okay, the other axis was only 16th wave. |

Glass Stress - X marks the spot
2013-08-05
|
| |
|
The black background is actually a white LCD screen with a polarizing filter blocking its linearly polarized light. If the glass (tool here) had no stress it too would be black. The stress in the glass bends the light and allows it to pass through the filter. This glass will be annealed and later made into a mirror. |

Scott begins hogging out his 8" mirror. According to the sagitta meter (the bar and gauge on the mirror) he reached about half of the needed depth during the first lab session. |

Brittany and her father, Stan, were working on 10 inch mirrors this week. Brittany's f4.9 mirror is fully polished and ready for figuring. Stan was visiting the lab for the first time and we put him to work in a 10 inch f5 mirror that will be used to calibrate the robotic Foucault tester. |
