Stage Micrometers for Reflected Light

This scale is etched through highly reflective vacuum coated metal. When viewed with reflected light illumination, as with a metallurgical microscope, the scale appears black against a bright background. Table of Accuracy

Image Analysis Standard, Reference Stage Graticule

Image Analysis Standard (Reference Stage Graticule)

Provides 4, high precision test areas designed for calibrating image analysis systems and identifying deviations and distortions in optical imaging systems.

The standard, which can also be used as a high precision stage micrometer, is supplied with recommendations for its use and an individual certificate of calibration.

It is produced on a 75mm x 25mm slide and has a square grid accuracy of ±0.1µm and a dot accuracy of ±0.3µm (except for the smallest and largest two dots on the root-2 array where accuracy is ±0.5µm).

The four test areas are:

  1. A 400µm x 400µm square grid which is subdivided into 200, 100, 50 and 25µm squares provides a means so detecting gross image distortions and can be used as an accurate two dimensional stage micrometer.
  2. A 20 x 17 array of nominally 15µm diameter dots can be used to identify lens distortions. i.e. to set the field of view to eliminate edge distortion.
  3. A root-2 array of spots from 3µm to 48µm diameter is used for determining the threshold level of cameras and microscope systems.
  4. A log-nominal distribution array of 100 spots ranging from 4.5µm to 27µm diameter enables the mean and standard deviation to be determined and compared with the certified values. This is an idealized distribution of maximum dynamic range for a full screen.

Supplied with a Certificate of Calibration from NPL (National Physics Laboratory, counterpart of NIST in the UK.).

Note: NPL is part of the International Metrology Group so that all of its measurements are directly traceable to the International Metre Standard held in Paris, France. This means that the certificate is internationally traceable.

England Finder - S7 Slide

Locator and Calibration Slide

England Finder Slide
Progressively enlarged view of slide surface.

X (A through Z, excluding I) Y (1 through 75), note K34 to right.

 England Finder Slide 2
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 prupose 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 an 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.
