Re: Pyrex glass coverslip

I agree with the others who have posted re: plastics and polymers. It
would probably take some research to get the refractive index of some
of these, but maybe something on the market would fill the bill.

You don't mention if you *have* to use something like Pyrex or fused
silica (for example, with a heating stage). If that's the case, a
polymer obviously won't work!

If a plastic/polymer *** is a possibility, there has been some talk
among the confocal folks re: a polymer called CYTOP, and its use in
imaging. Apparently the engineers at Olympus are now (or have been)
working with Asahi Glass Co. to bring CYTOP to market for this purpose.
The refrative index is reported as 1.34166

The properties and characteristics are found at:
<http://www.agc.co.jp/english/index.html>, then search for CYTOP.

I have no idea if this stuff is pre-cut in coverslip sizes or if you
have to buy it by the square meter. There is a "contact us" link on
the CYTOP. It might be worth leaving a message at Asahi's website, or
maybe contacting tech support at Olympus.

Two other possibilities:
Aclar
Thermanox

Good Luck, hope you find what you need!

Hi all,

Does anyone know where I can get coverslips made from Pyrex glass or some
other type of glasses??
I'm looking for coverslips with refractive index closer to 1.45-1.47 range
than usual 1.515 and cheaper than fused silica.

In some old literatures, I could find use of Pyrex coverslip but the
authors didn't list from where they got such stuff.....

Thanks!
