Some time ago i have this Idea to use rubber to adjust a laser to another to make a magenta laser.


I start building this Alloy Housing for the Rominsen RL-B7 Host.
Its pretty small diameter to put two aixis in it!
From inside is has a 12 mm diameter drill with only one fixing screw.
This hold the Blueray wich is inline with the mirror.

Mirror is from PHR sled, in the sled it work just as turning mirror, i think, but it works.
405nm go across and red is mirrored!

Theoretical its possible to put a greenie instead of the blu one IF the beam is big enough!! :(

The red module has rubber on one side in two axis.
In this two axis i have two screws wich give pressure to the module to get pressed in the rubber.

Without pressure from the screws its tight fit with the module the rubber and the housing.

The combining optik is glued seperatly on a angeld milled alloy mount, this is seperatly glued in.
I dont have the right tools to mill the angel in one build with the housing.
This suck for the aligning later, but i have no choice.



Like allways In this kind of builds it sucks to mount it complete because you have to pay attention that jou not twist the wires!!

2 setscrews in the top cover and another 2 in the side of the head.

For the Canon Camera its only red, unless you focus direktly in the optik.  :(

Its powered by two 123 3,7V lithium.
Both with rckst, the bluray in the pill.
The red makes a lot of heat because he has to drop much power.
I have no diode on hand to fix that.
Solution to make it work is just a small plate of alloy heatglued on the red rkstr.

Both drivers are well isolated with elecrto tape and heatglued to the driver pill.

My mobilphone can catcha the real colour of it while my Girlfriends Canon 350D cant.

After i have the cap removed i need only one minute to aligne the beams again that god that iam happy.
Outside, at long distance, 20 meters for exaple, boths beams are side by side. :-[
From time to time i have to work on alignment again, maybe the rubber is working? some ways
But its not a drama its fun to work on the alignment and lase around. ::)

Indoor at 5 meters the beams look like perfekt aligned and the visuel impression is bright magenta.

It pops black ballons easily at 2 meters!

The red lpc Diode is at 280ma well underdriven.
Blu PHR diode is at 120ma.
Alltoghether the complete build put out 230mw on my Laserbee.  :cool:

Iam happy!

Re: Magenta Project

Nice bit of machining there! You have your own lathe and mill?

That does look very neat and not a colour many people will have :) Can you light them individually to get tri-colour, red/BR/magenta?

Re: Magenta Project

No i dont have the machines at home, iam in luckily position that i can use the maschines "after" work from the company i work for.

At the moment both lasers are together in one power circuit wich is switchd :(

I think about, but i find no solution for that.
Any idea where and what switsh to use?

Re: Magenta Project

Rubber does tend to flow under pressure, could you try spring steel?

The easiest way is 2 push buttons press either one or both..... but you would need 2 supplies as using the switch to break the output would cause problems.

Out of interest what circuit are you using to be able to share the output?

I think about but i could not find any with a usable form.
It must be quardatic 8x10 mm.

I think for the moment its ok with Just one switsch.

Re: Magenta Project

I have used bits of the winding spring from a clock in the past for this kind of thing... another thought, though I haven't tried it, is an old recoil spring from a mower/chainsaw pull start.
