單位校正用標準微米尺 | S-Series

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 Stage Calibration Standards.

Two types are available:
Transmitted light
Reflected light, as is used with metallurgical microscopes

Stage Calibration Standards

These stage micrometers differ from the standard stage micrometers in that they are 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.

Calibration by NPL: The National Physical Laboratory carries out measurements at selected points on the scale and grids and issues a certificate of calibration. 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.

Measurement by Graticules Optics: For applications which do not require the accuracy or traceability 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.
