Ok so If you look at my sig you will se that I have a 250mW 650nm laser from lazerer.Now it came with an acrylic lens that was IMO a piece of shit. I wanted to replace it but I didn't have any 635-660nm glass lenses, so instead I took a 405-445nm lens I had laying around and put that on it instead. I am currently getting around 305mW out of it whereas with the acrylic I was getting around 265mW.
So the big question here is wether I am going to damage my laser by using a 405-445 lens on a 650nm laser. I'm assuming the issue here is that the AR coating is not optimized for 650nm so I could end up causing COD due to light reflecting back at the diode.
Am I worrying for nothing, does it even matter at these powers? All answers are greatly appreciated.
