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

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

Excellent

Love it

excellent quality, excellent price!

Almost pro quality. Not nist certified, but are you doing professional work? I am a professional and let students use this. I use it too for spotchecks. Pull out the one thats $$$$ and certified seldom so it isnt damaged.

Good calibration slide at a great price.

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

Top notch - excellent quality

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 scale jumps right out in the image and it looks very professional. It comes in a nice protective case as well.
