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

Excellent price for a stage micrometer.

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

Perfect!

does what I need it to

Meets specs exactly and I got it fast. Good job.

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.

excellent quality, excellent price!

Seller Amazon does themselves a disservice by not showing a clearer image of the calibration marks on this slide. The marks are photo-lithographed metal, probably sputtered onto the slide in a vacuum chamber similar to a semiconductor manufacturing process. The circle surrounding the 1.0 mm ruled line is about 3 mm in diameter and approximately 30-45 microns wide. The 1.0 mm ruled line is divided into major divisions of tenths, or 100 microns per major division. The major divisions are delineated by longest lines. Each major division is divided into two intermediate divisions by intermediate-length lines; so 50 microns per intermediate division. Each intermediate division is divided into five smallest divisions of 10 microns each. I estimate the line width delineating each small division to be about 2 microns wide; so were talking about very precision manufacturing for this calibration slide. Note that I cannot vouch for the absolute accuracy of the length of the full 1.0 mm graduated line. I can simply report that the full graduated line is divided very evenly and precisely into 100 small (~10 micron) divisions. Very impressed. The only negative that I have to report is that the ridges inside the plastic cover do not support the slide thickness very precisely. Consequently the slide has some play within the case when transported. Wrapping the slide back up in the thin paper in which it is originally packaged inside the plastic storage case solves that problem.

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

just what it should be.
