Pioneer-115D 300mw open can red diode

[p1t8ull]

if its the same diode that i done the testing on then at 60 feet it was a 12mm spot using the optics from a aixim module, about 0.437 mr thats with a 4 mm at front of optics measurment

Nice one, thanks Kaz

your not thinking of changing all them diodes are you simon

[p1t8ull]

Naa, but I have an interesting use in mind for these...

How did your test one go Andy? Still working ok or has it gone to the gods?

[andy_con]

funny you should ask

i looked at one and it went, but the other is still working just fine and still 300mw

can toy tell us more on this project??

[p1t8ull]

These seem to be a tad more fragile than other DVD diodes, going by the reported early failures...

can toy tell us more on this project??

Just an idea at the moment...

Good to see red diodes jump up to another level though, good work by Kaz and yourself

[andy_con]

well keep me posted, even if its by PM

i like your red projects

Maybe those big blocks of aluminum are to keep the laser from falling off of the silly putty that is under it.

Haha - I was thinking the same thing.

Andy another thing to consider is that heat sinking dissipates items to the ambient temp - or well tries to. When using a TEC to cool it is best to have the diode as close to the TEC as possible. Then heat sink the hot side of the TEC to keep the temperature difference as high as possible.

If you heat sink the cool side of the TEC you are reducing the efficiency of the TEC and adding extra heat.
