Pro Series Stage Micrometers
for Transmitted and Reflected Light


Pro Stage Micrometer for Transmitted Light

The Pro Series accurate stage micrometers are intended for routine calibration of light microscopes. Manufactured with a vacuum evaporated chromium images on a glass disc. The scale is centered on the glass disc and mounted in a stainless steel slide, 75 x 24 x 2mm thick. Each slide has a unique serial number. The Pro series stage micrometers are supplied in a polished wooden box to distinguish as a traceable standard. If you don't need certification, you can also check out our Standard Series Stage Micrometers.

The Pro Series Stage Micrometers can be supplied with a choice of three certificates:

  • GRATS Traceability, Certificate of Comparison (Graticules measurement)
    This is a manufacturer calibration to provide a traceable standard. Intended for applications which do not require the accuracy provided by calibrations carried out by NPL or UKAS. Graticules provides a Certificate of Comparison for the scale which is compared with an NPL calibrated in house standard. A statement of accuracy is included. Example of Certificate of Comparison.

  • UKAS Calibration Certificate
    A UKAS accredited calibration laboratory carries out measurements at selected points on the scales and issues a calibration certificate. The UKAS certificates are internationally recognized. Example of UKAS Certificate.

  • NPL Calibration Certificate
    This is a calibration carried out by NPL (National Physics Laboratory, based in the UK). NPL carries out measurements at selected points on the scales and issues a certificate of calibration which is internationally recognize. NPL, NIST, and PTB work together on an international level and recognized each other's calibrations.
    Example of NPL Certificate.
    For the NPL certified Pro series stage micrometers we have a re-certification program available. The stage micrometers have to be in good condition to allow for re-certification. The turn-around time is 6-10 weeks.

The dual scale calibration stage micrometers have the benefit of dual imperial/metric scales. The Pro series dual calibration scale is available for both transmitted light (black scale on glass) and reflected light (light scale on dark background). These scales are intended for calibrating optical products with a large field of view such as stereo microscopes, video microscopes and imaging systems. The scale is manufactured on a borosilicate (type B270) glass slide, 76 x 25 x1.5mm thickness with a unique serial number on each slide. Supplied in a polished wooden box.

• Horizontal Scales: 50mm in 0.1mm and 2 inch in 0.005 inch divisions
• Line thickness of 12µm
• Full glass slide; 76 x 25 x 1.5mm
• Transmitted and reflected light versions
• Individual Serial number for traceability
• Also available with UKAS Certificate

Pro Series of Image Analysis Standard (Reference Stage Graticule)

Reference Stage Graticule Image Analysis Standard, Reference Stage Graticule 2280-26 2285-26

  

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.
