Old as the hills by the looks of it, but I've not come across it before. Looks super-simple and fast to use and way better than fiddling with a micrometer.

Shame I already measured a few years supply, I would have liked this gizmo much better!

That's a wonderfully elegant design!
I have no need to measure cover slips, but I appreciate just seeing the gauge!

A model of out-of-the-box thinking!

Give me lever small enough and two fulcrums on which to place it, and I shall measure its thickness.

Clever idea from a PhD student at the time that gauge was made - with an illustrious career to follow: https://en.wikipedia.org/wiki/Shinya_Inou%C3%A9

One should wonder why this has not been commercially developed.

Microscopy is a pretty small market in the scheme of things - probably why no one has yet bothered?MarkSturtevant wrote: ↑Sun Aug 15, 2021 6:02 amOne should wonder why this has not been commercially developed.
Hobbyists using hand-me-down or cheaper new scopes probably don't bother to measure coverslip thickness.
Labs and suppliers with tight optical imaging needs are probably happy to use (just grab one) and sell (selling the "blades" rather than "razors") pricey 1.5H "high performance" coverslips.
A stand-mounted micrometer is about as quick and cheap (some under $50) or even a cheaper digital caliper for those who both care to hit .17mm and are frugal enough to sort through a batch. It takes someone like Inou to want to optimize this sorting for their own use.
