In this report, we present curvature measurements and optical test results for 15 unaluminized detector mirrors from Sinclair Glass. By combining the results, we conclude: mirrors #6, #10, #11 and #12 have excellent quality and are recommended to be the detector mirrors; mirrors #7 and #9 can be reserved as backups; mirrors #2 and #8 are sent for the aluminization. Optical tests will be repeated after aluminization, so that reflected spot characteristics can be compared with our first result.
