will this lens be ok?: 808nm 3 layer Glass Laser Collimation Lens/ M9P0.5*12.8MM Frame w/h Cushion Ring | eBay

i'll sure use a safety google......also i'll track where my IR dot go and how it's focus with my hand phone !

Im currently having a low powered 532nm green laser,but unfortunately it's very low power until it won's be able to burn thin plastic,until the focus lens is removed and plastic were put right infront of diode. As i know,a low power dpss green laser has a high powered 808nm diode behind it as...

Re: DTR's Laser Shop: 445 M140 Diodes $45 Shipped US Diodes-Drivers-Lenses-LEDs & M ok then,i'll place order in these few days,looking forward to it !! btw,i dont have LPM,so i'll assume that it's output power is 1.5W when driven by 1.5A. :)

Re: DTR's Laser Shop: 445 M140 Diodes $45 Shipped US Diodes-Drivers-Lenses-LEDs & M hi,i would like to buy ur m140 diode as shown in this page($64 version): https://sites.google.com/site/dtrlpf/home/diodes/445-m140-didoes i'll also buy a 1.5A microboost driver too! Im planning to buy them in...

i would like to use 1.5A microboost driver from DTR,but it's abit expensive ...... and it does require additional heatsink,i dont have source to get a small piece of aluminium! if i dont use additional heatsink,what will happen to the driver when it's overheat?will it fail?after the driver...

goggle....omg i've make a big mistake and i dont realize it !:yabbem:

Right now,i don't have idea about laser host,i also don't need a laser host,because i can't carry it around here and there,as it's very dangerous,maybe i'll just stick it on the heat sink,just like the guy in video do!after all,i just want to burn stuff !! About the power source,i may use 4x...

i do know the risk of 445 nm,i read it from here : Blue Light Hazard that's why i spend another $60 to buy eagle pairs,if not i could juz use the current cheap laser google i have and use the $60 to buy another laser diode!

First,im a newbie and i would like to build a high power 445nm laser! the video i reffered is at here(im not going to follow exactly what the guy done in the video) : How to build a cheap 1000mW+ blue laser - YouTube the doide im going to buy is at here (im buying the $64 version) ...
