Collimating beaulieu lens

[salt-sg]

Hi S8 Booster,

How much cost is required, to get a collimator?
I have some C-mount cameras which must be adjusted, but not money enough.


Well, I thought that the Schneider has a simple and very solid structure.
So I guess that most cause may be in the camera body, especially if the back focus is short.

Hey, thanks for all those replies!

supa_ate_sixteen, 17.52mm isn't the thread but the distance between the centre of perspective and the film plane. The thread is 25.4mm, according to the Beaulieu manual.

salt-sg, the mount is ok... that isn't the problem, but thanks for the idea.

Matt, I didn't think that "I reckon" was such bad English ... or is it? Anyway I think "shiese" should be spelt "cheese".

Pedro, where do you get your lenses collimated - Bavaria?
You and S8Booster are definitely right about this normally being a job for a professional ... all the same, I've dismantled and reassembled two zoom lenses without adversely affecting the image quality: a 35mm SLR lens because 2 screws INSIDE the lens had fallen out and were rolling around, and the lens on my NizoS55 which fell apart in my hand when I got it from the post office.

Maybe I'll give it a try. I'll keep you informed how it turns out.

Hello Salt-sq san.

Pedro says the costs in will be about 50 EUR in Germany which equals about ?6,000.- I believe.

I do not know if this is easy to get it done in Japan these days but I believe there must be a authorized Beaulieu dealer somewhere that can do the job.

Anyway there must be a vast number of other lens specialist companies in Jappan that can do tit.

I tried to find out if there was any available companies that maintained Canon cams in Japan a few years ago but I was told that there weren?t.

Maybee its easier with the Beaulieu?

Just did a wild try here if you haven?t been there already:

Hi,
just found this page by Martin Baumgarten: http://lavender.fortunecity.com/lave...llimation.html
It seems to cover the most important points of homemade collimation except for one ... exactly what is the "adjustment slot on the rear optic" he's talking about? Any idea?

Hey Vurfer, yes, Bavaria is the next place for me. After phoning them, in most cases you can wait for small adjustments. But you must consider, that their first priority is the maintainance of studio equipment, and if there is a problem during film shooting or a on-air transmission, we private customers have the second priority.

I think there is no special Beaulieu service needed to adjust the colimnation of a Beaulieu lens. There is NOTHING to do at the body. The adjustment is made at the back side of the lens, right in the same way as with any other tv, 16 or 35 mm lens. So any company that services camera equipment for film and tv probably can do the job.
