10 diode 445 build

[andy_con]

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

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

[tonyaztec]

Furry nice, good job

[taggalucci]

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

[andy_con]

olike lens, beam is 35mm at 18 metres

[logsquared]

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]

a beam looks like this (I)

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

[danielbriggs]

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

[logsquared]

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

[andy_con]

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

As usual, another great build, Andy.
bet you go through a lot of plastic rulers--lol

Great build Andy. You da man.

How about a balloon popping video?

[planters]

Very nice! Looks like a Kavant re the tight, simple lay out.

[andy_con]

simple is the way forward

[taggalucci]

Any tips for setting the mirror depth on the 45 degree angle?

It occurs to me that unless you have lateral adjustability in either your diode block or your mirror flex mount, getting the edge of the mirror at the right depth to overlay each beam is going to be near on impossible!

Nothing is ever simple.

Only simple people.

Right on brotha! The more complex the machine the more problems your gonna have.

Wow, I bet that's 10 Watts of blue there!! Cool. Nice, Andy.

[edison]

10 watt That,s allot of blue Like the topcovers too

[Carl B]

Very nice Andy.

Could do with one of these for my Laser Harp.

not impossible, but you do need a milling machine to do it.

if you glue the mirrors on the mounts exactly the same then its simple to get the holes for the mounts in the perfect place

it wont be producing 10watts, i suspect more around 7watts

thanks

if you got the money ive got the parts to build you one carl

I am facing the same challenge in gluing the mirrors to the flex mounts. I am not too concerned about tweaking the alignment on the screws, but a very consistent vertical glue up sure would allow a tighter packing. Did you use a jig? Any tricks?
Same issue on the diode. Any tricks to setting the stripe dead straight vertical.

[Carl B]

Thanks for the offer Andy but Rob is going to sort us out with a two diode unit when he gets time.
Besides I think 7W in the harp is a bit much for the house.

i set the diodes vertical without lens on. i just put an object in front of the diode and using the edge/line (I) to get the diodes right.

i have my own silly method of glueing the mirrors on but its not very technical. just do what works fpr you, just make sure each is the same
