Stage Micrometers for Transmitted and Reflected Light

Stage Micrometers for Transmitted Light

These accurate stage micrometers with optional certificates are intended for routine calibration of light microscopes, particularly when alternating objectives of different microscopes. Ideal for student, lab settings and instructional purposes. Robust and precise construction. Manufactured with vacuum evaporated chromium. Scale is centered on a glass disc, mounted in a black anodized aluminum slide, 75 x 24 x 2mm thick. Patterns are protected by a 0.13mm thick cover glass.

Stage Micrometers for Reflected Light

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

Calibration Certificates

UKAS Certificate (#2280-61)
A UKAS accredited laboratory carries out measurements at selected points on the scales and issues a calibration certificate which is internationally recognized. Example of a UKAS Certificate

NPL Calibration (#2280-62)
This is carried out by the National Physical Laboratory. NPL carries out measurement at selected points on the scales and grids and issues a certificate of calibration which is internationally recognized.

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.
