These stage graticules are intended for the routine calibration of eyepiece patterns, particularly when alternating between objectives on one microscope or when using the same graticule in different microscopes. Their robust construction makes them ideal for student use and for instructional purposes. The scale or grid is centered on a glass disc mounted in a black anodized aluminum slide 75mm x 24mm x 2mm thick. For applications requiring traceable standards, see page 507.Two types are available:
- Transmitted light
- Reflected light, as is used with metallurgical microscopes.
A. SCALES AND MICROMETER
For Transmitted Light
- New Dual-Scale Calibration Slides
- 2” Imperial (English) and 50mm Metric Scales on a Single Slide
- Positive and Negative Versions
- Unique Serial Number for Traceability
- Available with Internationally Traceable Certificates of Calibration
EMS has introduced two new calibration slides that have the benefit of dual imperial/metric scales. The PS52P is for transmitted light applications and has a bright chrome positive image. The PS52N has a negative pattern, formed in low reflective chrome for incident light applications to give excellent contrast. Both are ideal for calibrating optical products with a large field of view, such as stereo microscopes or imaging systems.

A stage micrometer with very well defined lines. These reference scales
offer substantial improvements in definition over the standard types when
used under the highest magnification. This is made possible by the use
of diamond cutting tools and a special ruling engine.
The S91 has clear lines ruled through a semi opaque metal film, which with transmitted light, appear as bright lines on a dark background.
The micrometer is made on a glass substrate 76mm x 26mm x 1.2mm thick. The lines are 1 micron wide or less and 3.5mm long. The metric rulings provide a scale of 1mm divided into 0.1mm parts, with one part being sub-divided into 0.01mm parts.

B. STAGE CALIBRATION STANDARDS
These stage micrometers differ from the standard stage micrometers due to the fact they are being available with a certificate giving precise details about their accuracy. These calbrated standards provide traceability for the precise calibration and confirmation of accuracy of optical measuring instruments, which is necessary under ISO provisions.
These standards are differ from the stage micrometers listed in the pevious section. The glass discs are mounted in stainless steel slides with engraved serial numbers. Each slide is supplied in a polished wooden storage case to distinguish it as a traceable standard of high value. We can arrange for the calibration of its scales and grids to be carried out by the most appropriate laboratory to suit the customers requirements – the choice of laboratory is normally dependent on the nature of the calibration and the accuracy required.
- Calibration by NPL: The National Physical Laboratory carries out measurements at selected points on the scale and grids and issues a certificate of calibration. Order Code NP. The NPL is the English equivalent of NIST.
- Calibration by UKAS accredited laboratory: A UKAS accredited laboratory carries out measurements at selected points on the scales and grids and issues a calibration certificate. Order Code: NA
- Measurement by Us: For applications, which do not require the accuracy provided by calibrations carried out by NPL or a UKAS accredited laboratory, We can provide a Certificate of Comparison. The scale or grid is compared with NPL calibrated in-house standards and a statement is provided on the accuracy of the item with respect to these standards. Order Code GR

This high precision image analysis standard provides four 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:
- 400µm x 400µm square grid which is subdivided into 200, 100, 50 and 25 micron squares provides a means of detecting gross image distortions, and can be used as an accurate two dimensional stage micrometer.
- 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.
- A root-2 array of spots from 3µm to 48µm diameter is used for determining the threshold levels of cameras and microscope systems.
- A log-normal 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.

Calibration of microscopes and image analysis systems is becoming more sophisticated, with the requirement being for a variety of image patterns to satisfy the numerous parameters. We’re now introducing a new multi-function calibration standard specifically for these applications.
Multiple images on a slide provide the most cost-effective solution to calibration and resolution checking of microscopes and image analysis systems. The combination of scales, dots, circles, squares, rulings, grids and angles can be supplied with an internationally traceable certificate of calibration for those who require ISO conformity.
Each glass slide has a permanent serial number and can be supplied with full or partial UKAS certificate of accuracy.
Starting from a fixed ‘Datum Point’ mark, each individual pattern or array can be located using X, Y, coordinates.

These are used to create precise volumes of liquid to enable counting of particles in a specified volume of liquid. A thick slide (glass or plastic) has an area cut into its surface that will hold precise volumes of bathing fluid. The shallow well, facilitating easy counting of contained particles. In use, a single drop of liquid is placed on the slide and a coverglass is placed on the platform providing equal and accurate subdivisions of the fluid each of which can be observed for particle counting.
For use in water analysis, culture inspection, and any fluid where particles
per unit volume need to be determined. Available in two versions:
S50 is an economically priced plastic cell.
S52 is made from glass, with a chromium surface image. This is intended for professional use and when using phase contrast. In each type, a central cell is filled with fluid and a coverglass limits the volume to 1 milliliter. The grid subdivides this into micro-liters.
S51 is the spare cover glass for S50 and S52. Each cell is supplied with one cover glass.

Finder graticules are used to swiftly and accurately give a position of reference to an area of interest on a specimen.
S7 is a glass slide 75mm x 26mm (3x1") marked over the top surface in a way that a referenced position can be directly read relative to the locating edges. That means it is marked with a square grid at 1mm intervals. Each square contains a center ring bearing reference letters and numbers, the remainder of the square being subdivided into four segments numbered 1 to 4.
Reference numbers run horizontally 1 to 75 and letters vertically A to Z (omitting I) The main locating edge is the bottom of the slide, which is used in conjunction with either the left or right vertical edge of the slide.
All England Finders produced 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 another person in another laboratory can relocate at a later date, or the same position, 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 England Finder, taking care not to disturb the position, feature of interest can be noted. The feature can also be re-located at another place or time by reversing the procedure. A total of 100 positions on a slide can be accurately located.

For Rapid Semen Analysis – The Makler counting chamber is only 10 microns deep, which is one tenth the depth of other hemacytometers., making it the shallowest of known chambers. This quality chamber is constructed from two pieces of optically flat glass: the first is the chamber, the second is the cover glass, which has a fine grid pattern of 1mm squares and a center area further subdivided into 0.1mm squares. Four quartz pins of precise height hold the cover glass to give an exact trapped specimen depth of 10 microns.
