Galaxy Optics Frequently Asked Questions

Ultimate Image Testing Services

Testing Services:

If you have your primary mirror in for re-coating services or are unsure about its wavefront quality you may want to consider one of our testing packages. We can test your mirror for you and provide you with a honest and reliable analysis of its wavefront quality. We offer two testing packages to meet your needs. All testing services include a telephone consultation to discuss the results once testing is completed. Please see our web page about multiple platform testing and test data for more information about our test methods and data analysis.

Test Package 1: Optical Quality Assessment

This is our basic testing package and includes the Foucault, Dall-Null, figure of revolution (astigmatism and flexure), and imaging tests. Test Package 1 will detect errors of asymmetry, check for surface smoothness, check for overall correction, detect zonal errors in the optical figure and demonstrate the optics imaging capabilities. Test Package 1 can be performed on both coated and un-coated optics.

Test Package 2: Quantitative Interferometric Analysis

If you are looking for a full quantitative analysis of your mirror look no further than our Test Package 2. Your mirror will receive all test included in the Test Package 1 and then undergo interferometric testing. When testing is complete you will receive a full test data report that includes values for astigmatic error, Strehl ratio, RMS wavefront error and peak to valley wavefront error. We also include a interferogram and wavefront contour map. This test package requires that the optical surface be un-coated.

Pricing:

Package 1: All apertures 14.5" - 25" $125

Package 2: All apertures 14.5" - 25" $250

Coating Removal Service for Test Package 2: $50

Galaxy Optics uses a dilute solution of hydrochloric acid and copper sulfate to remove your old coating. This solution safely removes the old coating without affecting the underlying glass or optical figure.
