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

Top notch - excellent quality

Love it

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.

excellent quality, excellent price!

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

Excellent for what were using it for - scale for a single image to calibrate other images on that stereoscope at the same optical zoom.

just what it should be.

Perfect for calibrating field of view and more

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.

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!
