there is 200 mw diode in them (same as stenkat one), current is <250 mA, susie have 300mw diode , so they are more costless.
Otherwise, the DX seem easy to disassemble, and if their 200mw version is true (mean 100mw of green), it will be interesting to buy a 5mw one and try to obtain more power.
Buying some now.
 
Do the olike modules for 200mW use a 9mm pump or a 5.6mm? These look like the 5.6mm with a 500mW pump. Maybe 200mW with the IR...
 
You might want to apply some simple math before you bank on getting 200mW out of a 250mA input ... Just ain't happening. With an optimal efficiency rate of 25% assumed using low-cost crystals, 65-70mW is the best amount of green theoretically possible out of the 200mW model... The 80-100mW SXD modules I've worked with (and they seem to be the highest quality I've come across) use a half-watt pump diode, that should tell you something (and Optotronics use 1 watt pumps in their 150mW plus pointers - generally considered to be the best around).

Just another DX misrepresentation, nothing to get excited about.

One thing to note is the large resistor on the board of the 200mW, in all of the DX modules ive torn down, this lager resistor is used on the boards that have a 500mW+ pump.

I have a few of these in a box, the ones that use a 250mA drawing pump do not have this resistor. The problem with DX is that they are using the same pics for the 5mW up to the 200mW modules. So really you dont know what they are going to send you.

Good point - I stand possibly corrected (although if the current draw is actually 250mA then I stand by my ststement...).
 
LOL, if the draw is only 250mA I agree, but think youd be lucky if you even see 60mW of 532.

The ones that are worth it from DX are the 532 modules with the large resistor and a 9mm pump. I have had modules that have the 5.6mm (500mW) that will give a solid 90mW with an ir filter added.


Im guessing DX is hurting for sales since the FDA stepped in, which seems to have pushed them to sell modules which they are probably now shipping to the US. The better versions are usually marked with a red sticker on the base just above the board and a nice fat 9mm diode in the rear. Those ones are definately worth it.

Notice there is no *We dont ship to the US* tag anywhere in those ads....

500 mw 5.6mm diode exist ? im not sure
the max power that i have found is 300 mw 5.6 mm diode
higher power come in other package(9mm) and are often multimode
right?
 
Even the 150mW 5.6mm packages are multimode. There are several lasers that DX sells that are around 500mW and 5.6mm. Im pretty sure these are overdriven though. Never seen a spec sheet, so the exact specs im not sure.
 
Guess we'll just have to wait for reviewers to tell us if it has the big resistor or not.
It'd be cool if they started stocking hosts for the modules, although the fact that they don't have a spring really sucks :(
 
the module seems to be equal to the FIRST PHOTO of the 200mw diode at olike. now susie changed the photo of the diode...with a reglar photo of a 120+ or 90+mw diode.

Yeah i noticed that too, does this mean they will ship >5mW lasers to the U.S. only if they are modules like these and not complete units like the dilda?
