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

Cette règle est au format lame de microscopie. Les gravures sont très claires et précises. Si l'on n'a pas les moyens de s'offrir un oculaire ou un objectif avec réticule, c'est une alternative très intéressante!

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 !

The slide is made of thin glass and has clear, crisp markings for the specified divisions. It comes wrapped in paper, stacked between 2 pieces of foamboard inside a plastic box which is taped for shipping.Markings are clear under "200x" magnification, but the slide came with an oil film on the printed side which showed up as "air bubbles" under the scope. Easily cleaned off and "bubbles" are gone.Not sure how these are made but a wild guess would be silver ion deposition through a mask. Oil film is probably there to stop oxidation of the silver, so best to keep the slide in a humidity-free environment when not in use.

Ich habe den 0,01 mm Mikroskop Kalibrierungs Objektträger kostenlos zum Testen erhalten. Das Produkt wurde schnell geliefert und war sehr sicher in einer Kunststoffbox verpakt.Die Verarbeitungsqualität ist sehr gut. In diesen Meßgrößen kann ich leider nicht mehr nachmessen, aber alleine wenn man sich die „Druckqualität“ – oder wie auch immer diese feinen Strukturen aufgebracht wurden – ansieht, dann gehe ich davon aus, dass alles sehr genau ausgemessen ist. Die einzelnen Bläschen, die man auf den Bildern sieht fallen im Mikroskop garnicht so auf. Evtl. ist der Fokusbereich der Kamera etwas größer, sodass die Bläschen im Hintergrund auch scharf dargestellt werden. Die unschärfe bei den Vergrößerungen liegt an meinem schlechten Mikroskop bzw. der mikroskopkamera. Wirklich beeindruckend. 8 Sterne

Accurate and easily visible. Compared scale to gage blocks, several precision steel rulers, and the reticle in an old shop microscope. It does what it says, and the dimensions appear good. My limits for detecting error visually will be about 0.01mm. These scales are definitely at least that accurate -- and from the looks, I'd be surprised if they aren't micron accurate, though I don't have the ability to positively confirm that. The reticles appear perfect at 40x magnification.
