Omnichrome HeCd 356 Laser
I found an old Omnichrome Helium Cadmium laser on eBay a few months ago and had to have a look at it. HeCd lasers are used to produce UV light and generally output only a few mW of power. Sadly, this laser was broken and never fired. I don't have the tools to properly investigate the cause of the failure so I decided to do a quick teardown and then recycle the device. I have scanned the manual, warnings, specifications, and safety checklist in hopes that they may be useful for other hobbyists. I ran all of the PDFs through Adobe Acrobat's OCR so they should be searchable. Enjoy!
