    1W blue vs 100mW green?

    Just thought I'd add, the fatness of the 1W makes it much more visible from the side at a much greater distance. The 1mm thick green beam gets very hard to spot perpendicular to the beam after about 10 metres or so whereas the blue is much more easily visible over 20m. This is only at night...

    1W blue vs 100mW green?

    Keep in mind that the orientation of a 1W multimode 445 will vary the beam intensity as you turn it in your hand due to the rectangular shape of the bea,, which seems to make a fair difference at closer range, for beam brightness. At night, I find the beam of 1W of 445 to be a little dimmer...

    How to tighten a loose heatsink? (No set screw)

    For those of you that advised against glue... It's already done. I ended up using a similar idea to hakzaw, I wrapped my module with a single laser of aluminium foil, making sure it was perfectly flat and then press fitting the heatsink. Then I used dots of glue around the top, preventing the...

    How to tighten a loose heatsink? (No set screw)

    Hey Fiddy, I thought about doing a a set screw, but the brass portion of the module will only sit about 1/2 way into the sink, with the other half being filled with circuit board so that the button lines up. Plus, I'd have to get the grub screw and the tap to fit it. And no Pyro, I don't do...

    How to tighten a loose heatsink? (No set screw)

    Hi guys, I couldn't find any topics on this, (Maybe I need to hone my search-fu?) but sorry in advance if it's common knowledge. I bought a green laser host that has an aluminium heatsink ring. I expected it to be too tight for the module and need sanding. Upon receiving my module today I've...

    505nm diodes in use!

    The old version was 635nm I believe. Maybe they didn't update there pics? See start of this video.

    505nm diodes in use!

    I was under the impression that around 505 - 510nm was peak sensitivity for dark adapted vision? (If I'm reading the source right, and it's accurate) Source: http://hyperphysics.phy-astr.gsu.edu/hbase/vision/bright.html So technically the rep would be right IF hes referring to night time use...

    505nm diodes in use!

    Sorry if this has already been mentioned. After all the hype over green diodes being finally available in 505 / 515nm a while back, it seems they actually do have a practical use, despite not being ideal for projection. Flicking through a new Surefire catalog they have a new weapon LED light...

    Laser Stimulating Eyes to Focus More Effectively?

    You make some good points DrSid, I've used the hole trick when I don't have my glasses, except I curl my fingers to make the tiny hole. I think you've hit the nail on the head Cyparagon. However I don't believe it's as applicable for just a few minutes of lasering a day. Also, To answer the...

    Laser Stimulating Eyes to Focus More Effectively?

    Hi Guys, Long time lurker and first time poster, sorry if this should be in another section. :) I have noticed with higher brightness lasers such has my "1mW" ;) ebay 532, and my 1W 445 home build (thanks DTR) that after pointing them and viewing the dot around the backyard (distance of 10 -...
