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

Excellent

I am very pleased with this calibration slide. The image is exceptionally sharp. I use it to determine the size of contamination specks in plastic films at 40-400X magnification. Typically, I can lay the film on top the slide and get a quick characterize the contaminants, if any, by size and color.

Works well for calibration.

Perfect!

Markings are practically invisible to the naked eye, but crisp and clear under magnification.

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.

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!

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

Love it

Excellent value.
