Often referred to as the Pharmaceutical PSA pattern, European Pharmacopeia pattern or IMA Reticle (USP 788).
Normally used on a microscope with 10x objective lens so that the main circle diameter equates to 1mm at the stage. If other objective magnifications are used, request a quote for a special calibration factor. We recommend that the PS8 Micrometer Scale with UKAS certificate of calibration is also purchased to calibrate the G57 reticle and provide measurement traceability for ISO.
