Hello Markus,
This is probably a long shot, but i'm going to look at a Fp2 with a weinlich E1003 controller tomorrow.
Did you manage to retrofit it? And if so, what components did you use?
All information is welcome.
All the best,
Dennis Dijkman
Hi Daryl, that sure is a beauty! Would love to get my hands on one of those electronic readout boxes one day!! Aaah a man can dream.
I'm also an electronics idiot, although maybe slightly more advanced ;) But hey, I'm learning!
All the best, Dennis.
Hello,
Nice find! Would love to see some pictures! I hope you'll get it working agian. If you do, I'll have some questions about the signal coming from the autocollimator going to the electronic display. And probably some other questions.
All the best,
Dennis
Hi,
Sorry for the late reply but I'll try to explain some of the questions I think you're asking.
First of, I didn't use any Leds in my attemps to read the output signal. This was done by one of the guys on the forum to simulate the vibrating slit and do some testing.
As far as i understand it...
Hello, did you get the information you where looking for?
If not, please send me a private message, i might have some more information about autocolimators you would like.
I also managed to plug the autocollimator into an Arduino.
All the best, Dennis.

Thanks for the input! And you are correct. And with the help of some people from another forum i was able to get it to work and actually measure it with my oscilloscope. Ive attached some pictures that show the 50Hz input sine wave to the vibrator sled (yellow line) and the output of the LDR...
No, the vibrator sled measured 44.5Ohms and the photo conductive cell measured over 40Mohms. There seems to be some differance in values depending on what autocollimator you have.
I will include a picture of the photo sensor, but its not really helpfull because its build in the autocollimator...
Here you can find the electronic schematic of the display unit (FA 70-3) with a list of component values.

Hello,
Some weeks ago I managed to acquire a very nice Hilger & Watts TA53 Autocollimator and a Hilger & Watts "Large precision clinometer TB80".
The autocollimator is of the Photo-Electric type, this means that there is a LDR (Light-dependent resistor) built in the autocollimator that can take...
Hi all!
This is awesome!! I was also trying to figure this stuff out.
Thank you Peter for putting in the efford of making the new circuit diagram and adding all the component values!!
I have a Hilger & Watts TA53 AC which is also missing its readout box.
I have scanned and uploaded my manual...
