10 diode 445 build

bit of a rush job but built this for a customer.

10x 445 diodes, beam is 5mm by 5mm @ aperture

Furry nice, good job

Nice! What lenses did you go with for that Andy? Do you have the divergence specs?

**andy_con** · 09-29-2011, 13:54

olike lens, beam is 35mm at 18 metres

**logsquared** · 09-29-2011, 14:06

I gotta know how you are getting a 1mm beam from a olike lens

Do you just waste the rest of the power or run the diodes at a lower current? Inquiring minds want to know

**andy_con** · 09-29-2011, 14:07

a beam looks like this (I)

all the power is in the I so dont bother with the ()

What current are you running the diodes at? Series / Parallel?
Nice milling

**logsquared** · 09-29-2011, 14:20

were you able to put a power meter on it? I am curious what the throughput was after the mirrors waveplate etc.

**andy_con** · 09-29-2011, 14:20

9v input, diodes in parallel with resistors - as request by client

thanks treacle

no idea dont have a power meter that will go thata high and only have a psu that will run it at half power
