Micro-Ruler MR-1, traceable, for traceable measurements or magnifications either direct or in images

The Micro-Ruler MR-1 is manufactured with anti-reflective chromium (30nm Cr2O3 over 70nm Cr) on soda-lime glass using highly accurate semiconductor manufacturing equipment. The overall scale extends over 150mm with 0.01mm increments with all labeling in mm. The ruler is designed to be viewed from either side as the markings are both right reading and mirror images.
The overall size is 25mm x 180mm x 3mm thick, the linear expansion coefficient is 9 x 10-6ppm/°C. Over its full 150mm length, the ruler will predictably change dimensions by 1.35µm/°C. The circles (diameter) and square boxes (side length) are 0.02, 0.05, 0.10, 0.50, 1.00, 2.00 and 5.00 mm. They are ideal to measure magnification simultaneously in X and Y directions or to determine image distortions such as skew, pincushion, barreling or other non-linearities.
The measurement uncertainty (accuracy) is ± 0.5µm over 0-10mm and ± 2.5µm over the entire 150mm length as measured by the National Physical Laboratory (NPL) in the UK. NPL is the NIST counterpart in the UK. The Geller MicroAnalytical Laboratory certification is made under ISO-17025 accreditation. The MR-1 is offered as a certified reference material (a traceable standard), recertification is recommended in 5 year intervals. See ordering information below for recertification service. Measurements should only by made by using pitch measurements, this is the distance between repeating parallel lines using either center-to-center or side-to-side spacing.
