4 Level Dot Crosshair Microscope Calibration Slide

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
