No manufacturer's information. The only thing we can find out about these is they appear to be cathodes for electron microscopes. Each is in an individual plastic case. Approx 1.25" diameter. If you have questions, please contact us. These came from a collection of ophthalmological equipment from a retired eye doctor. We cannot guarantee any information about them, but if you're looking for these, we'll be happy to help with any information we can give, and gladly offer returns.
