Why should you calibrate?

Calibrating your image analysis instrument with the appropriate stage micrometer
will assure accurate results

Confidence in measurement results

The risks associated with inaccurate measurements due to a lack of routine calibration can vary significantly from industry to industry and from lab to lab: false passes or failures in a production test, distorted findings in an engineering lab, non-conformity with industry requirements as to traceability.

Because of these risks and the costs resulting from decisions made due to inaccurate performance of digital instruments, we recommend using a certified Clemex Stage Micrometer to regularly calibrate your image analysis software and to be truly confident in your measurement results.

Images that reflect reality

 

Besides the obvious advantages of calibrating for measurement accuracy, the Clemex Stage Micrometer provides an excellent means of adjusting your color balance and correcting the shading imperfections of your camera with a reflected mirror surface (black square in the above image), resulting in an image that is a faithful representation of what you see through the eyepieces of your reflected-light microscope.

Designed to make calibration easier
 

A lot of thought and many years of experience with image analysis instruments went into designing the Clemex Stage Micrometer. 

Concentric rectangles of varying sizes (from 25 µm to 4000 µm) allow you to calibrate all your objectives without moving your stage when changing magnification. These rectangles are NIST Traceable and are used during automatic calibration together with the serial barcode on the side.

There are two sets of concentric rectangles so that both horizontally and vertically aligned specimen holders can be used for calibration.

The micrometer works just as well with transmitted light as it does with reflected light, the color balance and shading correction being done on any clear part of the glass slide instead of the mirror surface.

A 50 mm ruler is useful for calibrating a stereo microscope and a matrix of 250 µm squares helps see if the system has optical distortion.
