ASTM E1951 - STANDARD GUIDE FOR CALIBRATING RETICLES AND LIGHT MICROSCOPE MAGNIFICATIONS Organization: ASTM
Date: 2014-11-01
Description: It is essential that microscope magnifications and reticle dimensions be accurate.  The calibration using these methods is only as precise as the measuring devices used.
VDI/VDE 2655 BLATT 1.2 - OPTICAL MEASUREMENT OF MICROTOPOGRAPHY - CALIBRATION OF CONFOCAL MICROSCOPES AND DEPTH SETTING STANDARDS FOR ROUGHNESS MEASUREMENT Organization: VDI
Date: 2010-10-01
Description: This guideline is limited to the basic calibration of imaging confocal microscopes. By confocal microscopes measuring instruments are understood whose underlying principle relies on the imaging of a point source onto the sample to be calibrated in the illumination branch and the imaging of the light, returning onto a corresponding point-type intensity sensor in the detection branch.
DS/EN 60970 - INSULATING LIQUIDS - METHODS FOR COUNTING AND SIZING PARTICLES Organization: DS
Date: 2007-10-11
Description: One uses an automatic particle size analyser, working on the light interruption principle. The other two use an optical microscope, in either the transmitted light or incident light mode, to count particles collected on the surface of a membrane filter.
IEC 60970 - INSULATING LIQUIDS – METHODS FOR COUNTING AND SIZING PARTICLES - EDITION 2.0 Organization: IEC
Date: 2007-07-01
Description: One uses an automatic particle size analyser, working on the light interruption principle. The other two use an optical microscope, in either the transmitted light or incident light mode, to count particles collected on the surface of a membrane filter.
