Re: 2.2w 445. healthy laser for sale! PM on the way!!

But in this way you will not be able to measure the beam diameter with the CCD. Also, how are you going to solve the line up issue from the image obtained by the CCD?

I don't know if the linear CCD would work though, since a lot of times the beams are asymmetric and with linear CCD you will only get the cross section of the beam. Unless youscan the across the beam. The filter issue is fairly easy to resolve since you can have a combination of filters so for...

I watched the video, but I still don't know how you get to do the height map with the data from the webcam. :thinking:

Yes please. I am looking for that kind if software for a while. But no success. Please show us!!!

I'll try to see if the lab I work in has one. According to some people in the lab, there's a profiler somewhere. I just need to find it....

Unfortunately after examining your image in Photoshop, the image you taken didn't provide a lot of information. The center part of the beam is basically saturated. You need to filter out more light.

Microscope CCD camera with some neutral density filter. Easily under 200 dollar.

I looked at the data and looks like the Atomicrox's Peregrine seems to have some data been mark at same timestamp, but clearly is different data since the value is different. And this doesn't happened in Trevor's Peregrine. Perhaps this is due to the timer froze while the USB is still getting...

Hmm... The CSV looks strange... Some of the entries have the same time stamp. I never have this problem with my Peregrine while I was testing the Cube. And according to Trevor the timestamp is done at the computer side. So I am not sure if it has anything to do with my firmware. The attachment...

So you want the oled to mount facing forward and tilt up?

Hey, I can make a converter board and send it to you with the replacement board. It only cost couple dollar, and besides it will look better. Show me how you want to mount your OLED. Also, I'll try to find some plastic bushing to put between the board so you can get rid of the header and get...

I am thinking about taking off the OLED header on the processing board and let the wire out between two boards. What do you think? Also I think I will be able to change display orientation in the firmware. I will make it changeable by sending command through serial. Sounds good? Thanks Wade

I have enough part to make a new one. I'll send a new board to you with no charge. And, yes it is the original board since it is a mature design and the only thing legging me behind was the firmware. In the meanwhile, the inductor still works even with a chipping. Just so you know, the inductor...

Sorry not thorlab, the one I found is on Newport. Neutral Density Filter, 2.0 Optical Density, 1.0 in. Diameter You put 2 together and you got OD4 filter. And they work better with visible spectrum. You can adjust the OD by stacking several filter together. The one you indicated is for...

I have an idea of using a CCD camera with a OD3 neutral density filter. it should reduce the beam power into manageable range. Those filters are cheap form ThorLab about $40 for a glass one with 700w/cm^2 damage threshold.

For the Full pack with everything is $135. The base board is capable of data logging and supply power to Ophir and drive the display, which the price will be $80. The battery board allow the whole system be independent and would be $35. And the Bluetooth would be $20. And the special version of...

Okay, Finally got time to finalize the design. I will be selling these Ophir Backpacks in small quantity. I need to order the board soon so I can build it during thanksgiving. And I am offering these with several options. You can have just the data logging board or the full set with Bluetooth...

There are IR sensitive fluorescent materials made for this purpose. Check out Ebay.

That is actually not entirely true. The STM32F4DISCOVERY board is only $14. And it packed a lot more then Arduino.
