SUMMARY

The discussion focuses on the design of a 905 nm diode laser system intended for a scanning laser rangefinder, specifically addressing the feasibility of achieving Class 1 eye safety. The user seeks assistance with the eye safety calculations and inquiries about the relevant standards and approval processes. The goal is to ensure compliance with the ICE Class 1 standard, emphasizing the importance of safety in open-source hardware projects.

PREREQUISITES
  • Understanding of laser safety classifications, particularly ICE Class 1.
  • Knowledge of eye safety calculations for laser systems.
  • Familiarity with 905 nm diode laser specifications.
  • Awareness of regulatory standards for laser devices.
NEXT STEPS
  • Research the specific requirements for achieving ICE Class 1 laser safety.
  • Learn about the testing protocols for laser safety compliance.
  • Investigate the role of regulatory agencies in laser safety approval.
  • Explore open-source hardware design principles related to safety standards.
USEFUL FOR

Engineers, hobbyists, and developers involved in laser technology, particularly those designing laser rangefinders or similar devices, will benefit from this discussion.

Hi all,

I'd like some help calculating laser eye safety for a 905 nm diode laser system I'm building. It's for a scanning laser rangefinder and I need to figure out if my current design (a TOF rangefinder) can be feasibly be made Class 1 eye safe. The eye safety calculations are a little tricky and I'd like some help.
Thanks!

What standard covers this? What agency does the final approval? Is the final approval based on testing, or on submitting your design?
 
My end goal is an open-source open-hardware design, so there is no regulations other than my own conscience about putting out something dangerous.

My goal would be to meet the ICE Class 1 standard: http://en.wikipedia.org/wiki/Laser_safety#Class_1"
