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?
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:

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
