Brinkmann
Posted: Thu May 16, 2019 5:14 am
Here is my Brinkmann, I don't have much information about it and I welcome any and all information about it.
I have heard is actually a Zeiss model. If this is true, I am wondering how compatible it might be with other models should I choose to expand it's functionality at some point.
Design-wise, it is a 160mm DIN with a binocular head. The objectives are labelled Brinkmann, 3/0.08 (A0535), 10/0.30 (C0808), 40/0.75 (F0659), 100/1.30 (K0622) and are all parfocal. Both the 40x and 100x objectives are spring-loaded, though the 40x spring is very stiff and does not expand again without some assistance. I presume it will need some cleaning, but I do not yet know the correct method of doing so and have thus not attempted a repair.
The course and fine focus are separate knobs and when focusing, the arm itself moves instead of the stage. The fine focus only travels 4mm with a hard stop at both ends of the fine focus range. According to labelling,
one mark on the fine dial is equal to 0.002.
The condenser is marked KD-W 0.95 and has a swing out top lens, iris, and a 32mm filter tray; I presume the 0.95 is the NA of the condenser. The condenser drops into the condenser ring from the top and has a dovetail which the screws in the mounting ring clamp onto.
The illumination is via a lamp that sits below the condenser with a frosted glass disk at the top to diffuse the light. The bulb is tungsten bulb with an E14 base.
On the side below the fine focus knob is what I assume to be a serial number "36669" and what might be a model number "AS 2".
It came with 10x PL eyepieces, however one is cracked so I picked up a cheap set of widefields which are what's in it now.
If additional info/images can help identify, ask and I will try my best to provide more details.
Since a picture is worth 1000 words, here they are...
Here is a photo from the side, with the arm all the way down Same side, with the arm all the way up. Both of these photos show the suspected serial and model number partly obscured by the fine focus knob. A view of the other side, note the 4mm scale near the stage and the label. A shot of the bino head.
