Advice needed: Focus issues with laserbtb LP 515 20mW

[SilverFire]

Wow, I have never seen a laser beam exit the host at such a horrid angle.

Edit: I agree with mortuus, it would probably be best to send the laser back to Laserbtb and get a refund. Their plastic LP models do tend to be lower in quality than the HL or PL models.

*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 bigger host with a 520nm diode. No idea how reliable/durable the nano is, given that it's a DPSS still... I just want at least one pen, and I want a good quality pen to use as an every day fun tool... the btb LP is the only pen sized laser I got atm. I'm usually not into pens that much but I wanted something to carry when I want to take a laser with me. Well, but that probably belongs in my other thread where I searched for a green pen some months ago. Maybe I'll revive that as I might be searching for a new one soon.

since the 515 tends to heat up quickly i would avoid a pen with that diode and just use a 532, if u really want u should get the same diode but in a HL host i promise that would solve your problems and you will be able to focus it and enjoy it more.
