New Beseler LED Light source

[mshchem]

You have two different Beseler heads confused! The Beseler Minolta 45A is indeed additiive.
The Universal 45 head is SUBTTRACTIVE...both the variable contrast controller and the color controller have C-Y-M values
I purchased on new about 25 years ago, and printed color with the Universal 45 with color controller

Trust me the Universal 45 IS ADDITIVE. The CMY controls are used to make it easier to understand. Under the hood there's red, green, and blue fixed dichroic filters. The machine turns on appropriate lamps to expose the paper with RGB light . With the VC setup you substitute a clear filter for the center red filter. The green and blue lamps produce the appropriate light depending on contrast selected. When switched to graded paper mode only the center white light (clear filter ) is used. The same white lamp is used for focusing. When focusing with the color controller all 3 lamps come on, somewhat dimmed, to produce white light.

Wow, what a nice surprise! If I were still using my 45MX I would totally do this.

The Beseler Universal also uses a convenient YMC control panel for actual RGB narrow-band light, but halogen. So there's a precedent. But that particular design was not sufficiently thought out, and a number of the triacs in controllers were substandard. I've been involved with quite a bit of equipment design, not photographic,
but still analogous in the sense that you can put together a good prototype, but once you go to mass manufacture you can end up getting flaky subcontracted electronic components that murder the reputation of the product when it's barely out of the cradle. I ended up re-engineering a substantial part of my Beseler U system, and eventually turned it into a dependable high-performance "hotrod" of a colorhead compared to its original state. But it took awhile to psychoanalyze the schizophrenic electronics. The engineers were clearly geeks and not real printmakers, and Beseler was far less than helpful with the problems. Hopefully, this new product introduction will go a lot smoother.

I haven't, but please let us know what you think if you buy one:

which totals around $2,200.00, seem "affordable" in comparison.

I'm very curious if this has any internal moving parts. How it's actually set up inside. This is when I miss photography magazines. I would love to see a review.

Mike, you already got the answer to that directly from Beseler:

If it has dichro filters, which those rotating knobs are consistent with, it's got moving parts inside, just like Beseler's prior Dichro heads. I suspect the LED aspect is simply the "white" light source instead of using a halogen bulb.

I'm not entirely sure. I have a Beseler Universal 45 colorhead, the color version has red, green and blue dichroic filters in front of it's own EVW bulb. The computer controller adjusts the light, no moving parts to mimic with RGB the CMY that the operator calls for.

Beseler has said that the knobs turn very easily, cost and reliability might have allowed Beseler to do this by some electronic means???

It's like every new car has radio knobs that spin all the way around. Crazy, I don't know.

It could just be a LED version of the old faithful? I doubt I will buy one. I think these are designed for schools. Totally simple,

I've used my old Dichro 45S for over 30 years and I had replace the optoisolator on it. But it still works. I'm surprised that it's LED and they're still using dichroic filters instead of using PWM technology and RGB LEDs?

They probably had a serious distaste for RGB sources, after they partnered with Minolta for the Beseler Minolta 45A

I'm thinking about retrofitting my Dichro 45S with and LED. I already retrofitted a Xrite densitometer with an LED. Replacement peanut bulbs cost $600 each and I didn't want to pay for that much.

I got one of those in a batch of stuff. I never really tried using it. People who liked them really liked them. Maybe someday I will try. It sounds like a bug zapper

Is that the one like in the photo below.?

Nope no led display, only 3 leds for light source.

Oh...OK.
Do you have any experience with the type in the photo.?
I do not think i have ever seen one in use.

That's one I've managed to avoid. Overly complicated.

If anybody uses one of these, and they want to talk about, here is your chance...........................

That's the one that you can use the D.A.T.A. modules. I didn't have the money to buy one new. My first dichro head was the DG, with the separate blower and the big flexible hose. Worked great. I bought it used one snowy evening from Roger at University Camera in Iowa City, used for 500 bucks.

 

[Philippe-Georges]

Does this LED light source fits the OMEGA D3 (with variable condensor)?
the one on the right:

Sorry, i am relatively new to photography.
Was the DG one of the 23 models, or was that part of the 45 series.?
Thank You

Both, IIRC, The first dichro head I had was a Beseler head. It had a stabilized 22V transformer that mounted to one of the crossbars. There's a spring wound steel tape, it pulled out of the transformer and attached to the upper truss to help the motor lift the head. It has 2 halogen lamps, and a separate blower motor. In their youth these things were bulletproof, at least mine was. No electronics.
