Reflective X-Ray Optics LLC

The Amsterdam Avenue stretch between 125th and 145th Streets keeps a low profile, yet a high-precision operation operates in a third-floor suite near the C train stairs. Reflective X-Ray Optics LLC specializes in x-ray optics, with services that include mirror figure testing, thin-film coating evaluation, and detector calibration. Labs handling beryllium optics polishing and synchrotron beamline alignment also cross the floor, hinting at the local demand for fine metrology. Calibration of x-ray telescopes rounds out the lineup, which caters to research teams and instrument makers who need wavelengths measured to the nanometer.

If you need the door, find 1361 Amsterdam Ave #340, New York, NY 10027. Call (212) 678-4932 to confirm which service you’re after before hauling gear up the elevator, and grab the map on your phone first.
