0.01mm Microscope Reticle Calibration Camera Slide Ruler Cross Stage Micrometer Multifunctional Microscope Calibrating Ruler

Part of my work involves the regular servicing and maintenance of both stereo optical and compound research microscopes around our company's sites. For re-calibration purposes, I use a range of very good (but expensive) calibration plates and slides from several optical suppliers and manufacturers. I was interested in testing this relatively inexpensive item against the equipment I regularly use....This slide comes securely held in a protective plastic case, nestled between sheets of foam. Unwrapping the slide, i was surprised at how thin it was - but that simply means one must be a little more careful than normal when using it.For optical calibration purposes in our lab workshop, this slide proved just as good as anything else I already use - a remarkable performance for what is very much a 'budget' item.... I spent a whole day using this across a range of tasks on a variety of optical equipment - and checked each result against the standard calibration plates we normally use. Highly recommended thanks to its optical performance and excellent value !

Really good and easy to use - I have a very basic microscope with no scale on it - this solves the problem of trying to measure things effectively. It is very easy to read and even the smallest graduations are crystal clear
