My improvement was about a million percent with the Align-O-Tron. ------------------ Greg Mueller Amateur Astronomer, Machinist, Filmnut http://www.muellersatomics.com/  |  IP: Logged Freddie Dobbs Expert Film Handler Posts: 115 From: Pinson, AL, USA Registered: Jun 2001 posted 08-01-2001 08:35 PM                     Did any one figure out the cost of the laser, A theif in Atlanta has mine and I need to purchase a new one..  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 08-01-2001 10:59 PM                     I've been playing with one of these lately too and I must say I am quite impressed with the ease and accuracy of this tool. This beats the "string" hands down...no, in fact the string is a joke compared to the Align-O-Tron! I haven't done any light meter comparisons, but can state that the improvement in light output on screen does not need a meter to see the difference. Use it to align the lens holder/turret with the aperture, reflector and anode support and the difference will astonish. Highly recommended!  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-02-2001 07:04 AM                        There is no doubt that proper alignment will yield greatly improved light on the screen. Another benefit is improved contrast and less optical flare. In simple terms, if the lamphouse is not perfectly aligned, the light may enter the lens at a slight angle and "bounce around" inside the lens, increasing optical flare and reducing contrast. An analogy is trying to spray a stream of water through a drainpipe --- if the spray is perfectly aligned with the pipe, the water goes straight through, full-force. But if the water enters the pipe at a slight angle, much of the force of the water is lost, and some dribbles out the other end of the drainpipe. ------------------ John P.

This is what the Strong kit does, we've found it to be very effective.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-02-2001 01:18 PM                     I ended up doing that as well as makeing my own plugs for the 4K orcon and the cinemecanica zenith 2000H that insert from the front since there isn't any space behind the reflector that allows easy access for the plug I also machined a smaller apperture for the laser to reduce the spot  |  IP: Logged Greg Mueller Phenomenal Film Handler Posts: 1687 From: Port Gamble, WA Registered: Jun 99 posted 08-02-2001 02:05 PM                        I thought of putting the mirror in the pyramid part, but I was worried about people having to look at the pyramid during the lamphouse alignment phase and potentially catching an eye full of reflected laser. So I kept the two processes seperate. First you align the lamphouse, then you align the reflector. ------------------ Greg Mueller Amateur Astronomer, Machinist, Filmnut http://www.muellersatomics.com/  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-02-2001 04:25 PM                     The only problem in doing it in two phases is that you can end up moveing the back of the mirror off axis while moving the front to fire the beam back. Most lamphouses do not have the springs like the newer superlumexs but the mirror is fixed inside the box. So you need to be able to maintain the focus on the centre of the vortex of the mirros and shoot it back to the lazer in one step  |  IP: Logged
