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

just what it should be.

Nice to use, very fine lines well printed on the glass

I was wondering is there away by looking how many lines I can see what kind of magnification I have? I can count 8 lines using a 40 power objective with 10 power ocular. Thanks

Great slide and excellent image. Even better price for such an important tool to calibrate your microscope reticle or IA software.

Excellent value.

has only horizontal markings, you will have to rotate your camera to get vertical

does what I need it to

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.

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.

It was quite difficult to locate the small target zone under field conditions, but the markings are sharp. I cant vouch for the calibration without having compared against an expensive standard, but it matched almost exactly against another similar product.
