When I first picked up the laser, I liked the feel of it in my hand.
It is noticeably heavy and has that "well built" feeling.
The on/off tailcap switch is very nice because you don't always have
to hold down a switch when doing experiments and such. Brightness is
typical of what you would expect out of a 50mW laser, it is very
bright and it is almost too bright for star pointing because it
ruins your night vision! The price is also good too, at just over
$30 you can't go wrong!
Shipping took about two weeks from China, but it was free so I'm not
complaining. This site does ship to the US unlike DX/KD. It was
packaged well, as you can see it came in an interesting tin can
The case is padded with foam (which is black and is just asking to
be engraved by the laser), and it contains a cutout for the laser and a CR2 battery. It came
with a primary 3.0v CR2 so you can use it out of the box. I don't
know about the quality of the battery, but I don't really care if it
is good or not because you can get rechargeables for a couple bucks
The design of this laser looks nice and like I said earlier it feels
good in the hand. It has a rubberized coating on the outside so you
can get a good grip on it with it falling out of your hand. It has a
wrist strap so you don't drop it if you're clumsy ;D
Compared to the KD50
As you may know the KD50 is a popular laser that looks almost
identical to this one, but there are some differences. Besides the
fact that this site ships to the US and KD doesn't, a noticeable
difference is that this laser is a few mm longer than the KD50.
Also, this laser seems to have a rubber like coating unlike
the KD50, I prefer the coating but others might not. The switch on
the BG50 isn't as fiddly and weird as my KD50 which is a huge plus.
This laser doesn't have the "driect" spelling error
either. Output on the two is about the same.
As you would expect, this laser is very bright! For up close work
you will want to use goggles because the dot is so bright from up
close. The beam is visible in a lit room and much more visible in
the night sky. The beam is too bright for star pointing and might
mess up your night vision, but I think this is a good thing. This is bright enough to impress anybody you show it
to. The dot
always stays in a clean TEM00 so mode hopping is never a problem.
The beam diameter is larger than most other green lasers, but this
gives it better divergence.
Here's a picture showing the bigger beam diameter compared to a CNI
This laser is not a great burner because it is only a 50mW, but you
can pop balloons with it pretty easily. I can smoke the black foam
in the case it came in, and with a focusing lens I can light
matches, but that is about it. If you want a laser that does all of
the burning tricks this isn't the one for you.
This laser doesn't look like it has an IR filter, but it is nothing
to piss your pants about. Because the IR stays within the main green
beam, the only way to get exposed to large amounts of IR is if you
point it in your eye, and then you have more to worry about then
some IR exposure because your retinas are being burned by 50mW of
green. If you are still worried, buy an IR filter for $1 from Optotronics
and put it in this laser.
Overall this is a good laser, for $30 you can't go wrong.
