Shit i tought the choice would be easy. Still can’t choose which diode. I can’t find the NDG4216 anywhere. A quick search on ebay and DTR, i was able to find the PLP520-B1. What which diode would you recommend me for 100/200mW and a long lifespan?

Thats pretty cool. Is it siglemode or multimode? I noticed there are 2 versions. The pl520 and the plp520, i’m guessing the plp version is better right? By the way, what driver are you using? Sorry for stupid questions i have never touched any 520nm yet. Edit: in my particular design, i’m 100...

I will have a look, i believe this is the 55mW variant. How long do you have that 170mW diode? I’m worried about spending that much on a low life span if i push it as high as yours. Thanks

Hi, I was searching everywhere but i was stuck at the pl520 55mW and the massive 2W unit. I saw that the pl520-b2 was listed as 90mW, but others say its 55mW... Does anybody have a component number or place that sells 100/200mW 520nm diodes if they even exist? I heard Sharp was planning on...

Holyshit i didn’t know that! Must be some military kind of laser or flashlight for under water, thats pretty cool. Water is indeed excellent for cooling, especially in the sea! Yes! Thats a lot, but i ran this diode for 1 week straight on a power supply back in 2014. It doesn’t even have 1...

Hi, thanks! i'm not sure if its 100mW. Might be less. It can easily burn stuff and ignite fireworks within 2 second. Its very very bright. Brighter then everything i have here. The host is made out of stainless steel. The diode is firmly screwed and sealed onto a aluminum bus, which is firmly...

pictures of the device, laser is made out of stainless steel and its very heavy and solid for its size looking inside the lens is very statisfying. a lot of optics that went in there and it looks awesome. underwater beam. more photos comming soon

this is the other component screwed on the aluminum. all it is, is a aixiz diode holder. inside it, you could see an IR filter, inside a bracket. around the bracket is a rubber seal, to help centering the standard spring that comes with these aixiz housings, and to reduce noise. a better view...

this is my build i made 2 months ago. its the coolest build i have made so far. all exterior components and some interior components are machined by me. including the host, tail button, and Host is made from stainless steel. this laser is watertight, shockproof, fogproof [like purged...

Hi, those are all lenses. I think between 80 to 120mW. Rough estimate but it can ignite firecrackers in a second without hassle. Edit, forgot to mention, the driver was premanufactured, but its a replacement for my older driver Thanks! Awesome to hear that the laser i build still works, its a...

Hi, thanks! I think its putting out between 80 to 120mW. This is a rough estimate. The battery lasts surprisingly long. With my old driver, it died in 20 minutes. The new driver goes over 1 hour straight when used directly after charging. If you let it sit for a couple days, it will last 30...

Its more to get the beam comming out of the center of the lens, and to get it as round as possible. Otherwise you will get a shape that looks like a helicopter view of a car. And to seal it off

Here are the hardware pictures. Picture 1: the KTP crystal with an o-ring around it to prevent it from knocking loose when dropped severely or put on a firearm. Picture 2: two metal plates where the lens rests on, which is shown in picture 3. This prevents the lens holder to sit between the...

Its been a long time before i made another build. I made another green laser, i found enough time to make another one! Took me a while tough as it kept breaking and condensing. And i had to machine all the parts including the host. This is a very bright 532nm stainless steel green laser pen...

Hi, thanks :)

yes those where exactly what i bought. I got 2 blue batteries with a vent cap and 2 purple ones without a vent cap. They perform the same. Nice deal yea if you use them straight from the charger, at least on my build. It lasts 45 minutes. If you leave it a day it would be 25. But i have an...

Hi, thanks! I think it outputs between 80mW and 120mW. The current is set at 140mA. The beam is easily visible in the night without fog but the dot is hard to see at distance unless pointed at something that fluorescent

Hi, thanks! i also bought the 10280 from aliexpress as an set of 4 in may 2016. But after that the seller took his item offline and since haven't been able to find 10280. Costed me around $12 and they work like a charm!

Re: Watertight Rifle laser build 405nm Hi, thanks for your reply. If i have time i will build more! Thanks

I decided to build another laser. This time one that could be used on a rifle. It was hard. This laser has 2 removable circuit boards, a swappable diode and lens assembly, it runs on a 10280 battery and can be disassembled completely and assembled within 5 minutes. And the lens surfaces on the...
