New 3 Watt Customer Build

[gottaluvlasers]

Slick-

They were zip tied temporarily for pictures and for testing. Sometimes i use brackets, sometimes i use zip ties, sometimes i use both. I have had tiny screws and MANY holes stripped on the supplies with much more frequency than a single breakage or defective zip tie. depends on the build, the situation, and how everything else is laid out. In fact i have had customers specifically ask me to only use zip ties so that the supplies can be easily moved and or replaced if need be for upgrading.

Over 22 Professional builds over 3 years without a single defective unit or "dropped" power supply.

Perhaps before hauling sub-par accusatory remarks on build quality, maybe ask questions first. Not to mention this laser *is* going to be using brackets for the power supplies. However, they are still en-route from Jameco. I used only zip ties for now for pictures and for testing.

However, thank you for your warm concern and curiosity of "am i serious?"

nah, just you

Nice projector - is that a standard size box you use across designs ?

[carlos3621]

Marc, on the enclosures you use from OLSL:

whats the difference betweent the LT1000 and the LT500 ??
is it just different sizes ?
what are the dimensions on both of them ?

NICE JOB (simple)

Carlos

[flecom]

Just a simple 5V bi-polar actuator (i dont remember the make. sorry) and an aluminum flag. No i didn't make the bracket/flag. OSLS does them.

which bracket did you use? the GM-20 or MFE one?

[gottaluvlasers]

Frank-

MFE bracket.

Carlos-

it Yes, the only differences are the sizes.
LT1000- 24X12X12
LT500- 18X12X12

However, the variance has been rewritten. the "LT1000" covers *both* sizes. You just specify which size when ordering. they are both referred to as LT1000's now.

thanks guys! Much appreciated.

I have AC direct to key switch direct to power supplies. never used a relay in any system of mine or any that i built. Not needed. (IMO).

Keep everything as simple as possible. It will make things much easier in the filed.
Oh, and sorry, i forgot to respond to your PM the other day.

Here are the requirements for all lasers of all classes... You need to have a reset button on any class 4 laser that means if the power to the laser is shut off, you must go and press a reset button that has a time delay before starting (this is usually done with a relay and an on-delay timer), along with a housing interlock that would turn off the laser if the housing is opened up. Here are the facts.

I'm only trying to help you out here. You better go over all the requirements for being a Laser Manufacturer if you are going to be one.

[Doc]

AFAIK IEC60825-14:2007 SECTION 8.3.3.3 now superceeds that information.

8.3.3.3 Resetting interlocks
It is good practice for interlock systems to be designed so that, after operation, the system
can only be reset by a deliberate action (e.g., reset button).
Reset of the interlock system should then not be possible until all protective functions and
protective devices are ready for operation and any fault has been rectified.
Resetting the interlock system should not itself restart the laser but should prepare the
system to accept a start command.

So good practice, but not essential, which probably explains all of the approved variances Marc has achieved?

I appreciate your response, but you are 100% incorrect. I really don't wish to get into a pissing match with you in a forum, but according to my EOS (Emir Galevi) from the CDRH, and Dale Smith who confirmed Emir's statement to me, OSLS who holds a manufacturers license and is inspected at a minimum of once a year and builds more projectors than you, i and probably every other company on here combined, Interlocks *and* Resettable lasers ARE NOT required any longer on Laser light show projectors (that DO NOT use ion lasers that is) for a couple of reasons...

1- Laser laws and regulations have not been rewritten to inccorporate the change in the induistry with Diode/DPSS lasers. Ion lasers fall into their own category and some of the points you made are valid for ion laser projectors.

2- Solid State Lasers are wired such that if they dont receieve an input modulation signal, thay cant lase. therefore, if power is interupted, there is no need for a reset.

3- An interlock is only required if labels *are not* provided that warn of hazardous radiation present if panels are removed. If there are no labels, then *yes* an interlock is required.

4- Shutters need to be wired on all systems.

You need to have a reset button on any class 4 laser that means if the power to the laser is shut off, you must go and press a reset button that has a time delay before starting (this is usually done with a relay and an on-delay timer)

If the laser is a stand alone unit (i.e. a lab laser sitting on a bench) yes, you are 100% correct. If the laser is oncorporated into a show projector system, you are 100% incorrect. This was just confirmed on the phone with the CDRH. Time delays are satisfied now also becasue of the delay in lasing from input modulation signals. ion lasers are *always* lasing. yes, there needs to be a delay. Solid state lasers dont lase until told to by input from an external source.

I have filed many variances and have never once had a question or violation of the builds. I have also had a client inspection which passed with flying colors.

I'm only trying to help you out here. You better go over all the requirements for being a Laser Manufacturer if you are going to be one.

I appreciate your offer of help. However, i do my homework and I serve my clients quite well. I am proud of my impeccable track record and despite what you may believe to be fact or fiction or whatever, if i build it...it works as described. is 100% legal and has no question of manufacturing professionalism!

If you would like to continue this conversation, i would be more than happy to discuss it with you via telepohone or off forum. however, i dont think everyone here wants to read our stupid banter back and forth.

this was simply a thread to let some people see some simple pictures cuz we *all* love pictures and it has turned into a Soap Opera.

Soap Opera.

speaking of which, wheres LaserBen when you need him? LOL

[flecom]

variance... "LT1000"

you know it kills me that due to the insanity of getting a projector certified they can charge $2500 for a fancy box and people pay it... :facepalm:
