OMAX - FBA_CS-A36CALM1 0.01mm Microscope Camera Calibration Slide (Stage Micrometer)

The scale on the slide has changed and no longer matches images shown for this product. The 0.05 mm increments are no longer slightly longer than the 0.01mm increments - only the 0.1 mm increments are different length. This isnt a big deal, unless you have written your calibration software based on the older slide.

Its a little tricky to correctly position the sample to be able to see the calibrates, but it works

My kid needed this to calibrate measurements made under a microscope. This was exactly what was needed. Works great for that purpose.

This slide has a one millimeter scale, subdivided into tenths and hundredths (i.e. ten-microns). You can imagine, therefore, that the graduation lines are quite thin. Despite this, the outline of those graduations is precise and clear. Does the job well, and easy to use because of that clarity.

This is an inexpensive tool that will help you calculate your level of zoom. It does have a few erroneous specks around the scale but the scale itself was very clear.

Es una lámina portaobjetos de calibración muy práctica a la hora de determinar el tamaño de especímenes observados en un microscopio óptico.

I used this reticle to directly check the magnification of a digital microscope. The image of the reticle can be directly measure on the screen. (I found that the advertisement of the microscope in question contained an exaggeration.) With this information, the sizes of objects being viewed can be calculated directly. Of course, magnification is only half of the practical question -- the other half being resolution. With the clean lines on the reticle, one can get an idea of that too, but seeing by how many pixels the sharp line edges are blurred on the screen.

The ruler is a thick film metalization layer on the glass. This makes the quality much higher than the optically exposed film slide that I broke and had to replace! Nice!

Excellent value.

Excellent price for a stage micrometer.
