    Advice needed: Focus issues with laserbtb LP 515 20mW

    *blubbers* but I want a 515nm pen Q_Q well, I sent Kevin the mail that I accept the refund he offered. No idea how to send it back to china without spending a fortune yet but I'll see. My brother just bought 3 WL nanos (shush), maybe I can use the 15 mW 532nm one as a replacement and get a...

    Advice needed: Focus issues with laserbtb LP 515 20mW

    The magnifying glass was a good idea, should have thought of that ^^ and it doesn't seem like it's mode hopping. In fact I'm very sure it doesn't but then again I never saw a diode laser mode hop. The dot just "smears out" a little and mainly gets larger. I guess it's just the typical diode beam...

    Advice needed: Focus issues with laserbtb LP 515 20mW

    yeah, I usually really just use it as a pointer. So I usually don't leave it on more than a few seconds but also then don't really leave it off for 30 sec either. I guess I might use it for like 5 min or so, and during those 5 min I constantly turn it on and off (it has a momentary switch after...

    Advice needed: Focus issues with laserbtb LP 515 20mW

    mmmh, I thought so. I've seen lasers with bad divergence before but none where the divergence changes like this. The issue I have right now is that I'd actually really like this model, but a working one. One where the beam exits straight and one where the divergence is as good as it was when I...

    Advice needed: Focus issues with laserbtb LP 515 20mW

    I probably should add that I can notice a change in beam divergence even when not leaving the laser on. As in: Use it for a few seconds when the laser is "cold" >> just hold it in hand for a minute >> turn it on again >> notice larger laser dot.

    Advice needed: Focus issues with laserbtb LP 515 20mW

    I sure can: http://youtu.be/UlJL-ze_V0w It's at 4x speed. Yes, I left it on for like 3 minutes even though btb recommends a duty cycle of 100s on, 30s off. This hasn't been a issue before though, it's just a 20mW pointer after all. As I said, this is not about the general specs of this laser...

    Advice needed: Focus issues with laserbtb LP 515 20mW

    Hello everyone. I'm not 100% sure if this is the right sub-category, maybe this belongs into "laser companies" but I hope it doesn't need to get moved. I'm quite new to this board. In July I bought a 515nm 20mW laser pointer (the pen-sized LP host) from laserbtb. Unfortunately it recently...

    Searching for a pen-style laser

    ^ exactly what I was thinking... but thanks anyway for your contribution :3 tbh right now my favorite is the laserbtb direct diode, dunno if I can add a custom clip... Still, as I never owned a greeny under 100mW, is 20mW too much to point at a white wall? I don't want to blind people or...

    Searching for a pen-style laser

    xD well, I keep a lot of stuff in my pockets, I might get a holster/bag at some point, but as it is now, I'm having big trouser pockets, and I like to keep things organized in there so things don't get in the way when I want to reach something. Left pocket: Voltage indicator, Fenix LD05 (pen...

    Searching for a pen-style laser

    Hmm, I owned a 405nm in that host once, I didn't really like the host, the matte black finish went fubar and the threads are pretty cheap... But I'll consider it, although the pocket clip might break after some time... Maybe I'll find a way to add a clip to the laserbtb pen... I know someone who...

    Searching for a pen-style laser

    Yeah, I was just wondering how much a diffused 20mW point on a white wall or so would blind... I want something that is powerful enough to be seen, but I don't want to blind anyone looking at the dot... Still searching for alternatives btw, so anyone got some? n_n

    Searching for a pen-style laser

    Yeah, I haven't seen 532nm direct diode either yet o.O Well, anyway, I don't need that. I don't care much about this thread going OT but I'm still searching for a green laser pen ;) I really wish the 515nm pen from laserbtb had a pocketclip. That would make it perfect. The <5mW one seems really...

    Searching for a pen-style laser

    Thanks for your reply! Yes, I already knew about the Lyra, it looks nice, maybe a bit pricey for a 5mW 532nm. I don't like shiny stuff that much as well but that's not really important if the laser is properly built. I was wondering if a direct diode pointer would be more reliable, I read...

    Searching for a pen-style laser

    Hi, I'm new to this community and I'm really looking forward to have a great experience here. Hey everyone :) Tl;dr: Please help me find a low-powered, high quality green laser pen with pocket clip. I'm currently searching for a green laser for pointing purposes and I'm hoping for your advice...
