Quartz - Step Height Standards Wafer (SHS) - Brochure

TAKING PROFILER CALIBRATION STANDARDS A STEP FORWARD. Step Height Standards (SHS) are designed for the calibration of mechanical or optical surface profiler standards. These optical or mechanical profiler calibration standards consist of a 25 mm x 25 mm x 6.35 mm quartz block with a precisely etched uniform bar along with various test and diagnostic features. The choice of the material for manufacturing the optical or mechanical profiler calibration standard-an ultra smooth quartz photomask blank-assures a very flat and smooth working surface as well as parallelism of the top and bottom surface within a few seconds of arc.
