Model 292UTC Holographic Diffraction Grating Magnification Standard
This traceable, certified standard is a select grade. Each sample is individually measured in comparison with a similar specimen calibrated at the PTB. (This is the Physikalisch-Technischen Bundesanstalt. As the "national standards laboratory of Germany", it is the German counterpart to NIST in the USA.) The uncertainties are typically better then: +/- 2NM (average period) and +/- 2NM (single pitch value), where each range approximates a 95% confidences interval. See certificate of traceable calibration for details.
