'[OT] Infrared CCD'

Where can I find a infrared CCD (if it exist)?
Or a infrared camera (with PAL or digital output)?
Thanks.

Depending on the wavelenght you are looking for, most CCDs, if not all, are
sensitive (to a certain degree) to short IR (around 890nm). If you have a
video camera, try to see the light emmited by a remote control (IR of
course) and you will most likely see it blinking... :)

Some further info....

Some CCD devices (and cameras), especially black & white devices, are
equipped with an infrared blocking filter, to reduce IR sensitivity.
In some b&w cameras (e.g. Cohu) you can order the camera with and without
the IR blocking filter.

The Cohu B&W camera we used could image a pulsed infrared laser beam
(from a Nd:YAG laser) at a wavelength of 1064 nm.

Check out some of the data sheets for CCDs (on the WWW) from manufacturers
such as Texas Instruments.  They usually include a spectral response
curve.

If you are looking for an imaging device that is sensitive to long
wavelength IR (e.g. for applications involving thermal imaging) you
are talking about more exotic and expensive technologies than
"plain" CCDs used in visible light imaging.  [Check out publications
like Laser Focus World or Photonics Spectra for articles and
advertisements on this type of product.]

Remove the IR cut filter from the CCD in any camera
and you have a dandy near IR camera.

Not quite. Si is only good up to a wavelength of about
1100 nm (preferable 800-900 nm). If you want to go
beyond that you will have to use Ge or InGaAs or
InGaSb. Their use depends on what range you want
to be able to detect.

A japanese distributor is Hamimatzu, but prices
are exorbitant.

Good luck trying to find the right one (cheap one) for
your application.

Pedro

Pedro:
That is why I said "near IR", as opposed to those cameras
that can literally see you in the dark from your body heat.
Most CCDs peak in the 800-900 range.  They are covered
by a blue tinted flat glass which cuts their peak response.
That filter typically is held by a plastic snap-in frame, and
can be removed easily.  Then, you can do all sorts of
nocturnal wild life and spy stuff at night, using an IR diode
flashlight.

You may want to check http://www.polarisusa.com for CCD cameras, etc.

John,

sorry, I didn't read the word near.

       I believe that most if not all CCDs are infared sensitive, if you want j
ust
infared, use a filter. Just a thought... TTYL

Also check http://www.scx.com/ I have several of their PC-18 series units.
They work great.  I put one into a bird house with 5 IR led for ilumination
and watched the babies grow.
The need 12vdc and give conposit video out.
