yes, i saw that, thank you for the information! i let him know that if i am to go ANY further with this project, i need a laser meter to detune to lasers down to 4mW or less. im sure these 532 DPSS lasers are over 5mW, they emit a slightly visible beam, even in daylight.

if i am understanding this correctly, if the lasers are under 4mW, then i am safe?
Yup....

For a single individual laser --yes.

You need to find out what wavelengths will work with your customers "green screen" dircet diode green laser are not 532nm--they are 515nm or 520nm---probably the only green you can use for your purposes is a 515 10mW see: https://sites.google.com/site/dtrlpf/home/diodes/osram-10mw-plt5510-515nm-green-laser-diode Ask DTR ---if you are going to drive multiples of them 10 or 100 or whatever you will need a lot of drivers with the features you want for dimming. not just diodes . modules heat sinks and lenses and one or more DC power supplies/sources.--is going to get complicated fast

How the contraption you want to make and sell is seen according to regulators may be otherwise--they could require the entire device to be submitted for approval along with all the paperwork involved and questions answered---is definitely not a playtime project.
You need to consult with a qualified Laser Safety Officer in Canada--someone who knows what they are doing in the field of lasers.
To use it in Canada or USA in a business application (movie set or otherwise) you may need to get it approved for use and depending upon where it is to be used both it and your customer may need to meet the requirements of wherever that is also. see: https://canadianlasersafety.com/faqs/


REQUIREMENTS REGARDING LASER EQUIPMENT SOLD IN CANADA
Legal requirement
Laser equipment sold in Canada must comply with the Radiation Emitting Devices (RED) Act See: Radiation Emitting Devices Act

Under the Canadian Radiation Emitting Devices Act (REDA), it is incumbent upon the manufacturer, importer or distributor, as the case may be, to ensure that they meet the requirements of REDA, and regulations applicable to their devices. Health Canada carries out inspections (compliance verification) and can apply various subsections of the Radiation Emitting Devices Regulations to verify and enforce compliance of radiation emitting devices.

All manufacturers, sellers, importers and distributors of radiation emitting devices must ensure that devices comply with the applicable requirements of the REDA and, if applicable, other federal legislation and associated regulations.

See: Canada Radiation Emitting Devices Regulations Radiation Emitting Devices Regulations

See: Canada Consumer Product Safety Act

^^^ Good point ^^^
I was referring to a single Laser beam..

Do we even know what the OP is building
or trying to build...:thinking:

this is exactly the laser diode/driver combination i was looking at. DTR's 10mW 515nm with driver and body/glass lenses. maybe ill see if he can hook a few up to his power supply and see if they dim at the same rate... doesnt seem like a very complicated thing, but lasers are unlike anything i have ever worked with... its not simple like cutting steel, and then welding it to other steel...

interesting... i wonder how to go about looking into this... because ill make sure the lasers are under 4mW each, but a total for the entire unit would be 40mW... BUT on the same token, they currently have a device, that is being replaced by what i am designing that uses like 4 or 5 rows of 8 lasers per row. the problem with their current device is that each one must be turned on, and each one must have its batteries changed every hour. its a HUGE pain in the ass to set up, whereas mine is WAY easier.

this is actually a very good place to start... ask someone who deals with this stuff on the daily, and see if they have any concerns or whatever with the device that i am building...

its a 10 laser assembly for use in movies/shows. it allows for tracking during use with a green screen during the editing process. it gives the editor a point of reference.

thats hilarious! i actually put the whole thing together last night, without the lasers in it, and thought 'hell... im going to call this "Medusa"! then my Wife pipes up 'because you cant look at it?' and i freaking lost it haha!

:crackup:

LPFs very own "Medusa File".

Welcome to LPF, be safe man
Heres some suggestions for website I can give
(Get yo safety glasses) Survivallaser.com
Jetlasers.org
Sanwulasers.org
dragonlasers.com

Don't buy:
Wickedlasers.com(unless you really like the host and can justify overpaying for a laser)

Have a good stay

Can Project Medusa use any other wavelength?

If not you need to find out if 515nm will work with a "green screen" instead of 532nm green --they are quite different.

What are you talking about?
The above post has nothing to do with anything in this thread--is a completely disconnected from reality spam post

It is a SPAMed copy of your post #14 in thread: https://laserpointerforums.com/f37/new-forums-computer-science-student-interested-lasers-101908.html#post1508058

Regardless it is annoying that you put web site addresses that are not links---additionally you have no experience with any of the those web sites nor any of their products.

Stop spamming this disconnected post over and over.

If you have nothing to contribute, please don't post just to annoy people with meaningless unrelated posts.

I will have to see. As long as its faint, i dont think it should matter too much. The green dot on the green fabric would kind of dissipate, wouldnt it? The aim of this project is just for specifically placed dots on the greenscreen so the editor has a couple reference points to work with...

Also:

Working on making my first handheld laser body. Using 6061 aluminum leftovers from Medusa's heat sink body build.

Im learning more techniques with my lathe too, so im getting a few birds stoned at once. Ill try to post pics, but may have to edit them when i get back home.

Yes! Finally got the pics up! Hazzah!!

I posted those websites because I know they are trusted by other users, I don't need experience with the websites to give advice on some trusted laser sites. Shouldn't all newcomers have some websites they know will be good and are trusted by other users? And yes, they now have to copy and paste an address.

Sorry if this comes of as rude but you are getting upset at me for offering some trusted websites.

Keaton this will be your fist and last warning from me.
There's no need for you to post a list of trusted laser related sites on LPF every few days.
We have enough paid advertising on here.
Also, noobs can do a search or they can ask for advice.

Not only are you new here and get your nm and mW confused but also you have taken it upon yourself to become the de facto LPF welcoming advertiser/advisor.

Stop with these advertising posts.
I will issue you with this one and only warning.
Next will be a one week ban.
Continue after that and I'll make it permanent.

RB
