All, for an optical assembly I need to solder a quick testing setup. What's the typical current for a 5mW red diode.? Is it 20mA or 200mA??? Lost it somewhere... Thanks!!!

This may not qualify as a review, as it is not my intention to write an in-depth review about this laser. Many things have already been discussed by The_LED_Museum. Please see this as a complement. This is only an expression of my personal experiences with this laser. On january 5th, 2014 I...

Ok, so I got this PL450Bdiode from DTR. Copper module and a 100mA linear Moh's driver. Assembled al the stuff in a 501B Host with appropriate heatsink. The laser worked fine for several months. Then, a couple of weeks ago, it just faded out over a couple of seconds. It never has been on for more...

They come in 30mW and 50mW and prices are dropping : HL 520nm diode 30mW 50mW

...but I'm not that strong into electronics. OK, I have this PL450Bdiode with a Moghasm 100mA linear driver. I feed it with 2 1634 cells. That works just fine, but I want to use this laser for a different purpose, actually for targeting. For that, it would be of more convenience to feed the...

I just noticed Laserbtb offers a penstyle 515nm 5mW laser. Any experience or knowledge on these? LP 515nm 532nm 1-150

I am in the process of building a WF 501B M140 project with 1.8A Lazeerer X-Drive and Eudamonium WF501B heatsink (for the diode). As I'm reading through this forum, I see that some of you attach a separate small copper heatsink on the driver board. I see others attach the driver to the diode...

Hope they 'll get cheaper fast! Oh, and there's a typo : they speak 532 but the datasheet clearly says 520. Still not cheap at $200. OSRAM 532nm 50mW Laser Diode | eBay

Hi, I'm working on 2 445nm projects : 1. PL450B @ 100mA Mohasm driver 2. M140 @ 1.8 A X-drive Diodes are from DTR in module with copper heatsink, and I have the drivers from Lazeerer I need good quality hosts for these. I think the PLTB450 won't need anything special, and may even work in an...

(hope you all won't burn me immediately) I've been building 200 and 300 mW 650's before, with good results, but those were rather easy builds with off-the-shelf O-like/Rayfoss drivers and components. Now, I want something different, 445/450, but not your typical high power 445. I want to work...

Hi, I am an astronomer, and I like usig lasers for pointing my telescope at night. So, I used a 5mW green (beam visibility is OK for me) BUT the greenies allways die from cold temps because they are DPSS. I can use greenies only in summer. After that, I went with a 300mW red. Left that one...

Hi all! I am from Belgium, Europe. I am new here, but not new to lasers. I've built myself a 200mW red with aixiz components and before that I modded a 5mW DPSS greenie to about 30mW. Both work fine, but my question goes about a Blu Ray. I am not about burning things. Me and some friends are...
