300mW @650nm for $250

[QUAZAR]

They are multimode

6mm@3mrad

According to their web site, the specs are-

wavelength

650nm

cw output power

300mw

beam stability

5%

beam diameter

less than 2.5mm

beam divergence

less than 1.5 mrad

warm-up time

less than 10min

operating temperature

10~40 degree

storage temperature

-10~60degree

dimensions of laser head

125x36x40mm

beam height from base

9mm

power supply dimension

100x47x40mm

power supply

90-240V AC

weight

0.85Kg

2.5mm @ 1.5mrad, is a bit more respectable than the figures you quoted. Especially for the price.

I would love someone to confirm those beam specs. Has anyone bought one?

Hi!
This is my first post in this forum, normally I´m a quiet reader, and sorry for my bad english.
The beam specs with <2.5mm and <1.5mrad can&#180;t be. This red is a CNI red module. They only use one diode with a broadband Emitter.
So there is a big problem to colliminating these. Normally the output will be a big square with ~6mm diameter and ~3mrad, or so on (can&#180;t say exactly) These laser isn&#180;t a laser, it is a torch
If you want good beam specs, it is no problem for getting 250mW with 2 180mW Diodes per a "bad" polecube,this diodes have mostly good beamdata.
