Stage micrometers for transmitted light

Registered laboratories of the United Kingdom Accreditation Service (UKAS) carry out measurements and calibrations that are traceable to national measurement standards held in the UK's National Metrology Institute (NMI), the National Physical Laboratory (NPL). Each UKAS-certified micrometer available from Agar Scientific is permanently marked with an individual reference number, and is supplied in a baize-lined wooden box.

Stage micrometers for use with transmitted light are available with different line lengths and subdivisions as follows: AGL4201 (10-mm scale, 0.1-mm subdivisions, line width 5µm); AGL4204 (2-mm scale, 0.01-mm subdivisions, line width 2.5µm); AGL4078 (1-mm scale, 0.01-mm subdivisions, line width 2µm0; AGL4202 (0.1-mm scale, 0.002-mm subdivisions, line width 1µm); and AGL4203 (0.1? scale, 0.001?subdivisions, line width 2µm).
