I noticed that Dealextreme now does not list lasers above 5mW anymore ? Did somebody else notice that ?

Another interesting test: I bought two Varta NiMH 800 mAh Low self discharge AAA's. I tested the 2 year old DX true 50mW with it and the just received O-like 50mW. I did these batteries in one and the alkalines in the other. The result: regardless in which the new NiMH batteries were, the old...

I have three 50mW lasers twom from DX and one from o-like. All threec are powered by 2 AAA batteries. When I try alkalines all three work fine. When I try NiMH it is dependant on the type: fully charged it works best but one DX is still rather dim. I measured the current : the alkalines (open...

I just received this laser. So should I put the batteries with the "+" towards the rear as the DX lasers do ?

Which goggles can be good for 660, 532 and 445 wavelengths ? 405nm,445nm,808nm,1064nm safety goggles/200-450,800-2000nm [OLLS1064] - $45.99 : Welcome to O-Like.com, Your source for laser products Is this single one enough for all three ?

I out it on the central heating radiator (30oC) and then it worked. Is this really a temperature issue ? BTW the O-like are they really better ? Prices are not that bad does not differ much from DX.

OK the green lasers are not used for months, now batteries replaced, and no bumps or other shocks happened. they stayed just in the drawers.

Guys, Since summer 2008 I have two DX green 50mW lasers one pot modded and one 'true' 50mW. Until last summer they worked without problems although sometimes they got sometimes dimmer but after using longer they worked again normally. Now after 3 months of non usage they did not function...

When I point my laser pointer (regardless what color) at a bright surface, the bright spot reflects and acts as a bright light source. But the area illuminated by the laser has a strange speckle pattern. No, there is no error in my eyes as I see the same surface when illuminated by an...

During my Bali trip I saw at Hardy's shop in Sanur some guys offering lasers with special diffraction effects. I bargained one and got one for Rp 200k which is about $20. It is real fun. It is sold with three different diffraction heads which I tried on the red and 405nm blacklight laser as well...

But this is not a low quality phonecam but a modest SLR with a CMOS sensor. But you're right the sensor can be oversaturated, but why is our own 'sensor' (the retina) not oversaturated and do we still see the (very bright) red color ? Because the green and blue cones in the eyes are not...

Maybe more a photography problem, but when taking a picture of the red laser dot results in white. Maybe the depth of image of a camera is far less than the human eye (which sees it as really BRIGHT RED). I used a Canon eos 40 and show in RAW which I converted to jpg. Does anybody take better...

The image of @Elgranto7 slightly improved with some common laser wavelength in it. BTW, my red 200nm is considerably fainter than my 50mW greenie. So I think a 100mW violet is still way dimmer than the 200mW reddie.

Hi all, Here a re-post of my laser video of the violet laser from DX for $50, real fun ! Rather dim compared to my other two red and green but that is because its wavelength is near the limit of vision (405nm). YouTube - Blacklight laser 20mW from Dealextreme The laser is ffocusable...
