    Stickies updates?

    All of the sticky posts and links in the Lasers forum seem to be a decade old. Are there current answers to the following FAQs? How can I measure laser output power? (Last answer in stickies: "Go to a local university!") How can I check for IR output on a laser? (And if it's leaking IR, how...

    Why is Gen 3 night vision still so expensive?

    Now that digital infrared cameras can be found for under $100, and decent thermal cameras are under $1000, I thought I'd check on Gen 3+ image intensifier optics. They're still over $3000/tube! Why hasn't the price for intensifiers changed in the last 15 years?

    Variable beam?

    I'm looking for a non-rechargeable light with a 1"-diameter body and rear push-button so I can use it on my rail mounts. Maybe I'm misunderstanding specs but nothing I've seen so far offers variable beam shapes. For regular unmounted or close-quarters use I'd like a very wide beam, but I also...
