Have a problem finding shops that sell specific materials? Ask here. Are you looking for microscope parts? Do you have anything to offer for sale? Note: this is not a section for external companies to advertise their products.

Wanted: Leitz 50x NA1.00 Pv Quarzgl 0.18mm Glyz immersion objective

#1 Post by JMC » Sun Apr 17, 2022 12:38 pm

I have a few different, and somewhat unusual items, which I'm looking for for my UV microscopy work. I'll put a post per item up if that is ok.

First one, a Leitz 50x NA 1.00 Pv Quarzgl 0.18mm glycerine immersion objective. This was originally for a microspectrograph, but I am hoping someone perhaps has one they don't need.

Images of the front and back of one.

The images above are of the copy I have, and this has some markings which I am not clear on, which may not appear on other copies - Muster Fasserei, and a long number written in red.

This objective appears in one of the Leitz catalogues as item number 519 276;

I'm looking for another copy of it as I want to measure the transmission through it in UV. I'd expected the transmission to be good down to and below 300nm due to the markings on it, but my copy is not like that hence I am looking for another one to test against.

I'm based in the UK.

Thanks, Jonathan
