    Hobby Grade Laser Beam Profiler

    Oh yea, I never thought about those, the ones I have must be a similiar technology, or probably exactly the same. The ones I got were super cheap, and pretty easy to use. This one is 400dpi, but not very long, unless you want to profile huge beams though, it's fine. It's what I did my testing...

    Hobby Grade Laser Beam Profiler

    Yes, I agree. If I actually went ahead and built a fully working model, I think the only way to verify is to find if someone on here has a beam profiler, and send them my hobby grade one, if they were interested, to verify if it works. I think it's difficult to figure out how much filtering...

    Hobby Grade Laser Beam Profiler

    This is the guide I think I used: Blender 3D: Noob to Pro/Making Landscapes with heightmaps - Wikibooks, open books for an open world It states "when you add a texture, in the menu where you select 'image'" Follow that procedure, and use make the texture an image. If you need a guide on that...

    Hobby Grade Laser Beam Profiler

    I use Blender 2.6, It's called a Displace Modifier. Doc:2.6/Manual/Modifiers/Deform/Displace - BlenderWiki Basically, make a plane, the subdivide it to the resolution you would want the output. Then add the modifier Displace. For displace, you use a texture, click the texture stuff, switch...

    Hobby Grade Laser Beam Profiler

    Well i placed a few other gel filters, the ones used to put in the flash bulb for a flash photography to change the colors, well i layered red green and blue to make it as neutral as possible, and put the edmunds neutral density filter i used before. In a few cases I got the power down enough...

    Hobby Grade Laser Beam Profiler

    Yea, well I just did that real quick, as I said I have other filters in transit, so I was going to revist this once I get them and try them out. Also there are webcam settings which I didn't even play with this time. During testing the linear image sensor, I got a nice curve, much like what is...

    Hobby Grade Laser Beam Profiler

    Well, I couldn't stand it anymore, so I went ahead and attempted to use the CCD's on webcams directly, so i tore apart 2 webcams, a cheap gearhead, and a logitech c920 1080p. I used the small neutral density filter I got from edmunds, and surprise surprise, it works. If you hover over the...

    Hobby Grade Laser Beam Profiler

    Are there any hobby grade laser beam profilers on the market? Ones that would give a picture, such as this the picture below, that costs under $1000 ? I know I posted before about a beam profiler, but in my pursuit of profiling my own beams, I figured out a way to get a very nice beam profile...

    Beam profiling, best tools and diy ideas

    So are you thinking of item: NENIR40B-C from thorlabs.com? desc: Ø25 mm Unmounted AR-Coated Absorptive Neutral Density Filter, 1050-1620 nm, OD: 4.0 OD 4.0 describes optical density, it says transmission is only 0.01%, the others are less restrictive. I did do some other further testing...

    Beam profiling, best tools and diy ideas

    Thanks for your reply. I'll try some of the gel to reduce the beam, the welders mask lens that I used was flat, which I thought would be alright since it shouldn't affect to focusing to much. It did cause some other anomalies so it's not the most ideal really. Thanks for mentioning the...

    Beam profiling, best tools and diy ideas

    I'm new to lasers, only have a few thus far, but i'm trying to figure out the best way to determine the beam profile, or really just the primary diameter. Power isn't my primary concern, but of course using my techniques changing the power appears to change the size, although i'm not sure how...
