Levenhuk 2 Calibration Slide

This is a slide that is designed to calibrate an image analysis program. It is made of optical glass has several circles of different diameters applied to it (1.5mm 0.6mm 0.15mm and 0.07mm) and it has a micrometer scale with a division value of 0.01mm. The scale has 100 divisions and its total length is 1mm.

The Levenhuk 2 Calibration Slide has standard dimensions like those of a glass slide. Calibration should be performed for each objective separately; the resulting correction factor will enable accurate measurements in the selected units.

How to use the calibration slide:

1. Fix the slide on the microscope stage.
2. Rotate the revolver to select the working objective.
3. Set the camera to shooting mode at maximum resolution and then take a photo of the scale.
4. In the image analysis program select the calibration mode use the mouse to indicate the maximum visible distance and then enter the resulting value in real units.
5. Enter the name of the calibration and double-check the values.
6. If everything is done correctly the program will remember the correction factor and in the future it will independently convert the values into the required units of measurement.
