Do you have the photo of the driver maybe?

I think we have a winner ^^ Yes exactly it is looking linKe you say. Worse can happen is "S" effect when you are narrowing the beam and you do it in little bad angle. I'm using wireless webcam. Darken the screen and at 10-15 meter distance I'm watching the beam spot moving the lenses. With...

Probably knife edge would be the best, and additional telescope system at the output to change the diameter. Google acrtos in the internet ;) Arctos Multi Diode Array

I was hoping to find here someone also connected with this kind of drivers. I will post my work and discuss assets and defects to make them better ;) So feel free to criticize and discuss. I would like to make the boost driver, but all >1A step up IC are not available from my suppliers. I saw...

Hello, Today I managed to make the "lite" version of the driver. As I promised photos attached. Much smaller board - that is true and for sure price will be at least 20% lower. What do you think?

Since I'm quite new to forum members, maybe you know someone who already have prisms and would like to test cylindrical optics ;)?

Sure, just write me email or PM. I will make a discount.

As always with drivers I serve you well especially for higher voltages for diodes in series. The x cube has really a lot of power loos. I also bought them to make rgb laser. I wanted to put three diodes around the X cube, but... but it had around 70% efficiency it is decitaded for projectors...

I can help you a little with project using dichros. I was doing RGB systems already, I even have one small mounted on base plate.

I can send one pair of cylindrical lens as sample to compare it with anamorphic prisms in exchange for well made review of my lens vs prisms. The market price is now 65 USD. I know they are hard to adjust, but power loss <0,7%. What do you think about it guys? Maybe you Down with Umbrella ;)...

Ok, as you advised today/tomorrow I will prepare this driver in "lite" version. No heatsink, no D-SUB, the only problem then are mounting holes. Because 25 D-SUB is really wide, I just didn't care about holes and I made them just on the sides of a driver. I can cut off this parts of the driver...

You must use 35mm cubes? 10mm re much easier to get. Actually cubes are pretty easy to use. Important is to have turn regulation for diodes to get maximum output power. One source of light you fix with glue, second one you can move and turn adjusting to the first one. You are moving the light...

It took me a lot of thinking what to use and my arguments are: One channel driver is dedicated for laser modules which usually have multi wire cables for TEC, diode and temperature sensor. D-sub are more universal, can be bought on TME, farnell and people know what is D-sub, with other...

Hello Guys, I would like to post my another driver. This one is much more advanced and is dedicated for laser projectors and RGB systems. It took around a week to make a prototype, then order electronics, test everything with scope and apply changes. It can be easily seen that adding...

Sorry you are right. It started to be offtop a little.

I like the drawing, additional base plate can be significant. Total outside dimension is 34mm for my lens for 3,5W diode. As I told, the price can change easily especially for LPF members and also for >1 quantities. After registration on the site I can give proper discounts for the users. I...

Could you just make a test using Lab bench? Actually This kind of scope is quite normal for me, especially if we: don't use bigger capacitors like 200-400uF don't use 10-20uH Inductor for high current rates Do we have some really tiny boost drivers which have "flat" scope for 2-3A current? It...

You can find cylindrical lens on my website. There are also magnification parameters. Price is not very low, but problem was very expensive coating. I needed it to be >99,7% for one lens. So On two lenses you have only around 0,5 - 0,7% power loss. I would mount them on the flat surface as...

Correct! I'm from poland (together with friends). Here is the hello thread: http://laserpointerforums.com/f37/hello-poland-91146.html But incorrect that I'm using prisms - I'm using cylindrical lens pairs. The prices will change a little because we are editing the site all the time...

But you can cheat a bit ;) Instead of adding beam expander, you can take out collimation lens and use normal lens with for example 10 - 20mm focal length. Then total length will not be changed. And beam diameter will be correspondingly bigger. You can try it easily without changing the build.
