Canon A400 Conversion to an Infrared Only Digicam
October 4TH, 2009

I bought a Canon A400, because I had hopes that its CCD would be as easy to modify for IR, as the other canons I had modified. This camera seemed relatively straightforward to modify, but it actually involved a little soldering, and for this camera I had to glue the new fake filter into place. Most of the other cameras you can just set the new glass in place. Over all, I am quite pleased with the results, as this camera approaches 3.3 megapixels, so there is a lot to work with. Original retail price of around $180. Read the review of this camera on DC Resource, the BEST site for digital camera reviews.

To start with, here's a few shots of the outside of the camera.

Step 1:

Body Removed

The first step is to remove all the screws on the camera body. There are zero screws on the top. Three screws on the bottom. There is one screw hidden behind the Digital A/V port on the back, and three screws in the battery door.

Once the screws have been removed, use a small screwdriver to pry open the camera body. It will split in two down the top and bottom of the camera. Its a pretty compact little fellah.


After the body is removed, the front of the camera will look more or less like this.

Camera Back

The back will look more or less like this. Notice the LCD screen, and button tabs on the circuit board.


Step 2:

Solder!

You will need to disconnect the circuit board from the top of the camera in order to get to the CCD. There is one solder point. You will need to heat up a soldering iron to loosen the solder, then pull the wire out. You can then slide the LCD screen back and get to the CCD screws.

This image shows the wire removed from its solder point.


You do not need to remove the LCD, it can remain connected by the ribbon cable. Just move it out of the way so you can get to the CCD.

CCD Exposed

Step 3:

Exposed CCD

Remove the screws to get to the CCD. This can be annoying, because each screw as a gold washer like ring around the screw hole. They are easily lost, and breathing on them can cause them to move around. The IR filter is VERY thin. Much thinner than the microscope glass I usually use to replace the filter with.

What I ended up doing was cutting a small piece of that hard clear plastic that electronics some time come in from the store. The hard clear plastic that is a royal pain to cut through when you are trying to open up say, a new pair of head phones? I took a small piece of that, and a piece of exposed negative. Then I glued them into place, and let it sit over night.

It is important not to get any thumb prints on the CCD. Also, try not to let any dust or hair into the CCD/Filter area. I kind of kept the whole camera in a box while I let the glue dry, as I was afraid of sealing the CCD back up and screwing it in with glue fumes in the CCD area.

I let it sit overnight, then screwed it back together, re-soldered the wires back together and then screwed the camera body back on. Yeah, its that easy. ;)

Sample Photos:

Here are some sample photos I took with the Canon A400.

If you look carefully, you can see a dark kind of streak through the left side of this photo. That means that I have an issue with my home made filter. Its not perfect, but doesn't always show up as obvious.
