Lilly electronics 150mw 980/490 line dilda style pointer with laser pics.

>EDIT opon taking the lens of and looking at the diode i see what appear to be muiltimode lines like my 808 has. They said the rated current was 650ma and it only uses 420ma.
I got this about 2 weeks again and I'd say It's been great so far as I can see the line in a dark room without adapting to darkness and it's a sky blue line. This is the same seller that had the 980 pen.

Shipping
10/10

Got here in under 3 weeks from china before the estimated date.


Laser build
9/10
It's a standard style 6 volt laser. Could of been made to run of one battery and not 2 3.6v as it makes alot of waste heat. Generally IR lasers can be ran more efficiently.

edit I just tested it on my lab PSU. It draws 420ma at 3.15 and at 6.5 ish. The light dosen't change but 3 volts makes alot less heat.


Beam quality

6.5/10

I haven been able to get the divergence down below 2 ish mrads

turns out after looking at it on my cam carder it looks like it has muilto mode patterns with no lens on.

seeing how the beam only focuses into the line it supports this theory even more.

Overall 8/10

I would rebuy this since my samsung camera camcorder works like intend and it can make a night NV device. It picks up 980nm much stronger infact and is able to autofocus it like my 1 watt 808nm with no lens.

here are some shots/ stills from my camcorder

980nm laser - Album on Imgur

The wall was about 15 feet away and the switch about 9. I have no idea how bright the beam was there but you can clearly see the irregular beam shape on the wall just like in that picture my camera which was zoomed in all the way. I suspect they may have put a muiltmode 980nm and under driver it or do they just have bad divergence?

Btw my camera has laser burns from 405nm laser and not this.

Looks like this one is muiltimode. I'll upload pics but the blue line is def there. I saw it with no lens on the diode directly coming out at diffirent angle then the red light i saw.

just like that freak 808nm i have. I dunno if i should tell you guys about that yet.

I used to buy from lilymaria2002 on ebay, but without fail, every single laser diode or assembly they sold had power outputs which were half or less of what they said it was supposed to do. The listing I found says <650 mA, or under 650 mA, but 1/3 under seems a bit far from it, doesn't it?

At 980nm the divergence, unless the beam is expanded, is normal to be pretty bad, just due to the longer wavelength alone. If multimode, even wider divergence.

How did you get those burn marks on your CCD camera?

50mw 405nm laser even with a lens over it it to spread the beam out It seems CCDs in cameras HATE that wave length even worse then your eye does. I really feel bad about it this was before i knew it can see so well into the IR. If i ever see another used i'm buying it.


looking at it my camera it looks more like a single mode dioide just my my blue ray burner does.
