Detecting other wavelengths of light

[Book]

Do you know of any place that I could buy a camera that could detect IR visible UV light or any combination of these?

For example, I'd really like a micro-camera that could detect IR (preferable of a large range). I don't want it to have a high resolution, but it has to be sensitive enough. I've been searching on where to buy one but couldn't find anything good (most sites don't even mention a price wtf!).

If there is some other device that can detect even more wavelengths, then I want to know about it too.

Basically, would it be possible for a device to detect sources of radio waves, microwaves and any other light radiation all in a single device?

I've built a simple device for testing my Infra red LDs and LEDs. It uses a photodiode, an LED and a resistor in series for detecting IR (and visible light) up to maybe 1064nm. When the photodiode is illuminated, the LED lights up.

It's really easy to make and use.

I don't know much about UV though. :-/

Sites don't list their prices on IR cameras perhaps because your search led you to thermal imaging cameras.Now these are sensitive to very deep IR, 8-14um (radiant heat).The newer ones use an uncooled microbolometer as a sensor(and for some reason , companies need some sort of authorization to manufacture these) and cost in the thousands of dollars, and you need to special-order them. For radio waves you can use anything from an AM/FM radio to a walkie-talkie to a Wi-Fi detector, it really depends on the frequency range you're looking for.Maybe even one of those spycam detectors on DX.

It probably would , but I don't think they make them.

A camera that detects IR? Your making it harder than it needs to be! Grab a camera, take the lens off, and remove the IR filter (Pece of red/cyan ish colored glass). Put it all back together and your done

Of course it's gonna work only for NIR.790nm and 808nm will be plenty visible, but 980nm will get pretty dim.I don't even know if 1064nm shows up at all.Anyway, you can just get an IR filterless camera.The B/W camera needed for the kipkay IR nighvision hack was 12 or 18 dollars, can't remember.

Oh yea, and cameras work for near UV too, well better than the human eye anyway.

Yeah, I would really like one that could detect higher wavelengths IR (except near IR), as those emited by hot bodies. Are they really so expensive?

And when I was talking about the theoretical devie that could deetct all electromagnetic radiation, I was kind of picturing it having a monitor where you can view the source of the radiation is pseudo-colour. So example setting it to receive around 2.4GHz or radiation, you would see your cordless phone's antenna shining throgh the wall of your house!

And about the microcamera from kipkay's hack, I am talking about something like that, but the more IR the camera can detect the better. You know where can I get something like that?

Yeah, the monitor idea would be insane.But I don't think they even make sensors for radio wave to show them on a screen.I'm afraid they only make those for visible light, near UV and near IR, and the thermal imaging cameras(that unfortunately really are that expensive :'(, I wanted one so bad....and the cheapest I could find on ebay was a huge and bulky last generation one that uses a cooled bolometer and was going for around 200GBP as I recall...) Anyway, those things are wicked cool, you can see the thermal print of a guys hand on a wall from 10 minutes ago.Yeah , that one was $12k.As a cheaper solution maybe you could mod a motion detector, that will only detect it , not show it on a screen.

For a device like you described I guess you would have to have lots of sensors all connected to the same monitor.And even then you could only scan common wavelength ranges , not the whole EM spectrum.
