Leitz a10x Focusing Eyepiece for Binocular

$45.00

This is a single focusing a10x ocular. This ocular will ONLY fit in the right-hand eyepiece tube of the Leitz series of binocular magnifiers. These magnifiers resembled inverted porro-prism binoculars and were supplied in three variations with fixed magnification objective lenses (0.7x, 1x, and 2x). They are unique in that the diameter of the ocular tube is 31mm (instead of the more common 30mm), and the length of the two ocular tubes differed. The left-hand tube would only accept the ‘fixed’ eyelens ocular, and the right tube the focusing ocular. Consequently, the shoulders on the two types of oculars were in different positions. Oculars were always supplied in pairs with one fixed and one adjustable eyelens.

These magnifiers were first produced in the 1920’s, and production continued in one form or another until around 1980. Around 1970 Leitz changed the tube diameter to the more conventional 30mm, so if you have a very recent magnifier, you should double-check to make sure this ocular will fit!

The lens is in very fine condition – just the typical wear in the enamel on the focusing knurl. The lens is in perfect condition although it does not appear to be coated. This lens would date from the early 1960’s or very late 1950’s judging from the font face on the ‘Germany’ engraving. It is more recent than the other a10x we have available.
