Hey guys I just put an order in for some new NiMH C cells at BatteryJunction.com and they're having a 10% off sale on everything. Discount code is doomsday12w Considering getting a couple of quality Li ion batteries can be expensive I wanted everyone to get a chance to take advantage. One word...

So do you leave the batteries in your lasers? Yea or nay. Give reasons for your answer.

I would really love to get a 500mW 532 from lazerer and at one point I did but the unit was bad and max from lazerer was great with the return process, that was about 8 months ago. Now I'm interested in possibly trying again but my biggest issue is that IMO the host for the 500mW stick is way...

Title pretty much says it all. I have a DHOM 2W+ 532nm labbie (purchased from meierlight) and I'd like to collimate the beam a bit and also be able to adjust it as needed. I haven't been able to find any optics packages designed to go right onto the aperture of a labbie. The diameter of the...

As most of you know lasers have a listed life expectancy. For example my 1.8W 532nm DHOM has a listed life expectancy of 10,000 hours (this is an actively cooled labby and CNI lists 10,000 hours for similar laser systems). My 40W Co2 has a listed life expectancy of 5,000 hours. Now I know that...

Hey guys. I have an empty Lazerer Rifle host. It originally contained a 500mW 405 diode. I was going to start a new build with it (maybe a 445 or a 635 diode) but I would rather just sell it and get a new host. If you're interested in it send me a PM. The cheapest rifle model lazerer currently...

Ok so I received my 1,800mW 532nm labby from meierlight today and it's running strong so far. I plan on doing a full review soon but right now I want to find something out. Now the whole setup consists of the laser head with an 8-prong female cord coming out of it and the PSU. Now the cord is...

Ok I just recently purchased an 1,800mW 532nm lab laser from Meierlight.com and the analog modulation works by connecting 5V to input wires so 5V equals max power, 2.5V equals half power and 0V equals off. What I'm wondering is how many amps will this wire be able to handle because I actually...

Hey I just found this auction on ebay for a bunch of thor labs/newport lens mounts. It's for 25 of them for $99 which is a really really good deal for these things. Brand new these mounts are usually between 35-50 dollars just for one mount whereas this auction has 25 mounts with lenses in them...

So my 405nm Rifle from lazerer has just arrived and so far I am loving it. This is my first rifle from lazerer so I've been looking forward to this since I ordered it. One question I do have though is what makes a good lens cap for the rifle. I'm thinking I could take the null cap off and just...

Too many whiners.

First of all for those of you that don't know what a crookes radiometer is heres some short reading. Crookes radiometer - Wikipedia, the free encyclopedia So I was messing around and shining my DL Hulk100 at my radiometer trying to see how fast it would spin from about 12 inches away and it...

I've been looking around some of the popular optics and laser sites and I have had a hard time finding diffraction gratings that would be suitable for 1W+ lasers. My friend dans cheap green broke recently and he gave me the screw on diffraction gratings that you can spin and I tried passing my...

I'm currently in the market for a 1W 532nm lab laser. If anybody has one they are interested in selling either post here or send me a PM. Analog modulation is preferable but TTL is fine too.

Well I've been looking at the meierlight website ( meierlight ) and I wanted to know if anyone has any experience with them because there are a couple of lasers they have that I'm very interested. Are they trusted, are there lasers up to spec, are there greens IR filtered etc? Any help here is...

I posted a link to the website this is hosted on a while back but I don't think I actually posted this particular simulation so here ya go. Some very interesting stuff this simulation might be able to be used for. It shows you the result of shining a laser through different materials such as...

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...

I've been looking around a bit for yellow lasers either 589,574 etc. I know a few people around here have them I just can't seem to find any rated over 10mW. I know they can be pretty expensive I've been taking a look at CNI seeing as they seem to be the only truly reliable company with yellows...

Some dick head who lives not to far from me was recently arrested after illuminating a private jet with a 532 laser. The pilots alerted the authorities and when a police chopper was dispatched the moron proceeded to illuminate the chopper as well. Of course they found him and ground units were...

So I was going through my account preferences on the site and I was looking through the different layouts that you can choose and it made me curious about which layout everyone else is using so heres a poll to find out.
