 Exclusively from |
Magnification Calibration GuideUse this guide in conjunction with a 2,160 lines/mm grating replica for accurate determination and calibration of TEM, SEM, AFM and STM magnification. By measuring the distance between the lines of the replica pattern, the image magnification can be read directly from the calculator. (2,160 lines/mm grating replica specimens - our catalog numbers 603, 604 series, 606, 607, 607-AFM, 607-STM and 625-B.)

Micro-Ruler MR-1, TraceableThe minimum increment is 0.01mm. Circle diameters and square boxes are: 0.20, 0.05, 0.10, 0.50, 1.00, 2.00 and 5.00mm.Fabricated using semiconductor technology. Material is anti reflective chromium over soda-lime glass. Overall size is 25 x 180 x 3mm thick. Labeled in mm with an overall scale of +150mm. Accuracy is ± 2µm over 150mm. Forensic scientists place objects to be measured either over the scale or beneath it (scales are written in both right-reading and mirror image so the dimensions appear properly in a photo micrograph). National Physical Laboratory (NIST counterpart in the UK) Traceable Certified Reference Material. Geller MicroAnalytical Laboratory certification is made under ISO-17025 accreditation.

England Finder - S7 SlideLocator and Calibration Slide

| The England Finder is a glass slide marked over the top
surface in a way that a referenced position can be directly read relative
to the locating edges. All England Finders produced by Graticules for over 40 years are identical. The purpose of the finder is to give the microscopist an easy method of recording the position of a particular field of interest, so that the same position can be re-located at a later date, or by another person in another laboratory, or when using any other England Finder on any other microscope. The location of the arrows is identical for all England Finder slides. Mark a label on the left hand side of the specimen slide, indicating the orientation to be repeated. By replacing the specimen slide with the England Finder, taking care not to disturb the position, the feature of interest can be noted. The feature can also be re-located at another place or time by reversing the procedure. Over 1,800 positions on a 76 x 26mm slide can be accurately located. Slide thickness is 1.35mm ±0.05mm. Nominal line width is 0.025mm.
