Is that visible to the naked eye? I thought maybe only the camera could see it. amazon has something similar for sale . I am trying to make on with radioshack IR led parts 960nm, so I need a camera to see the white light. I am taking a phlebotomy class and thought it would help. Thanks for the video.

do you suggest some glass filters which cuts out excess light from interfering with the vein view area?

hey :)

I had written to you few days ago regarding the vein detector device, thanks for your feedback i tried putting M-seal and it now works a lot better, i have attached pictures of the product,

There's still one problem, veins appear as thick black lines only when the surrounding light is pitch dark, in ambient light the veins are hardly visible, can you pls tell me what can be done about this?

thank you

Hey,

Thanks for showing me your build! Really cool for me to see people put this instructable to use.

From your photos I'm seeing that the problem is LED light leaking into the field of view, where you would visualize the veins. The led light should be focused down and be blocked from shining into the middle area where you would see your veins. To do this I used friendly plastic, a product here in America. If you are unable to find this you can temporarily use some kind of puddy or clay pressed onto the sides of the LEDs.

Hope that helps, let me know how it works out.

Best,
Dan

thank you Dan,

I shall try it out asap and get back to you with the results
