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

does what I need it to

Top notch - excellent quality

just what it should be.

I used this slide to calibrate my microscope camera so that I will know the size of things that I take pictures of under the microscope. There is a 1mm long etching that is divided into 100 parts. The distance from one line to the next is 10 µm. By taking a picture of this calibration slide with each of the microscope objectives, you can calculate the size of objects by knowing which objective lens was used while taking the picture. Its sort of a one-time-use item but if I get a new microscope objective or a new camera, I can use this slide to calibrate that.

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

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

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.

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.

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

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