Default my blue module:-)

Some people have noticed that i was busy with developing a quad module. But when the blue 445nm diodes where available i decided to develop a single blue module in between the development of the quad. I had to wait for some parts to come in but here its is:

Brightlight laser 445-V1
Beam at aperture: 3.5 by 3.5 garanteed
power: 1watt
Analog and TTL modulation up to 30 khz
Size: 75mm x 40mm x 44mm
Size driver 102x 60 x 34
Beamheight 29mm so it matches with CNI and Laserwave
Pl members price 445 euro including shipment.
Warrenty 1 year after manufacturing

The module produces 1 watt of 445nm with a 3.5 by 3.5 beam at aperture. The divergence can be matched with your green and red when i know your spotsize at 10 meters. The lowest divergence is 0.9mrd but i prefer to match it with the customers green and red modules if they have them already. If they buy my upcoming red modules i will match my modules with the green modules that i,m going to choose.

The module is tec cooled by a peltier and the temperture is steady on 25 degrees. comes complete with driver and is tested to garantee the output.
Warrenty is one year. The size of the module is 75mm in length,40mm wide and 44mm in height. The housing is made out of aluminium and is black anodisized.

I ordered the labels so they will be there. I know many companies won,t show the internals but because most members know already how to shape the 445nm i decided
to show how i did it.

The dual and quad is on the way and will be manufactured next week.

If someone is interested i have 16 modules like these on my desk ready to be build in the next couple of weeks.

Default Re: my blue module:-)

feel free to say no,
I like the look of your driver.
I am using some self made coolers with tecs in my projector for my reds and green as well as my blue, been wanting a better way to control temp.
Is there any possible way you could give out the schematic/PCB design or just sell the board?
They look like great drivers.

Hello Kiyoukan

The circuit board is not the actual driver. Its a board for connecting the diode with the lasorb and the cable. I don,t like connectors in lasers because connectors can result in a bad connections and soldering is just the best connection. It also hold the diode into the diode chamber so it has a double function.

If you removed the circuit board behind the diode would it be possible to remove the diode without a tool?
also as kiyoukan said it would be nice to get a schematic for the tec controller, or you could sell them as ppl here would buy them.
also +1 rep for this awsome build.

so.. you want 445€ for this laser.. I bet you take 532€ for a green one.
Apart from the joke, this is a nice build. You might want to lower the price, seriously..

Silvershot, if you think its to expencive have a look at a Kvant:

1W/445nm laser module KVANT :: Synchrovision.co.uk

Same module with driver and tec cooling. The driver is a bought on with tec so i dont have the schematic. I bought a quality driver instead of developing it. I will have my own drivers in time but first my quad and octo for bigger reds is my main priority.

no worries silvershot , with all the blue modules that are for sale like o-like snoctony, and ultralasers it not easy to see wich modules have beam corrective optics and is a professional tec cooled module unless you have digged out how they work. Even Kvant gives his beamspecs in half angle. That means that the module of kvant has an actual divergence of 1.8 horizontal and 0.4 vertical divergence.

These 445nm diodes tend to give very good beams with no correction.. I'd like to see these modules with the Mitsubishi 638nm multimode diodes in them.. the prism pair should REALLY help those out.. as would the TEC. The 445nm projector diodes hit 60-80C routinely when still in the projector, so I doubt that TEC cooling is needed for diode longevity. It's nice to have though, for wavelength stability.

Those specs from Kvant mean that their modules do not have beam correcting optics. I get those same exact divergence figures (full angle) from all of my modules using only an Aixiz glass multi-element lens.

Thanks elektrofreak. You see silvershot even i still learn. I thought kvant has corrective optics in their modules but apperently not. I knew that my module was from good quality but i didn,t know my beamspecs are better because of the corrective optics. Time to compare them with a kvant module:-)
Tjee i have to get a 638nm diode.

I don't think the kvant modules have the same diodes in them - apples and oranges.

Not necessarily.. based on those divergence figures and the fact that pretty much all current 445nm laser diodes are made by Nichia I would say there's a strong likelihood that the dies are very similar, even if the cases are not. Regardless, if there were corrective optics in there the output should have lower divergence and be more symmetrical.

When the diodes suddenly where available from the DLP projectors, Kvant slashed their prices from 2100 euro excl vat for a 1 watt 445 to 570 euro excl vat. As electrofreak mentioned he gets similar results with the blue diode using a triple lens. I,m pretty sure they use the same diode. So you pay 570 euro excl vat for a brass mount with tec and driver that delivers 1.8 mrd divergence. So i think mine is better at a lower cost. I will ask on PL if someone has a Kvant module and want to compare it with mine.
