Removing Infrared (IR) Filter From Microsoft Lifecam Studio


Introduction: Removing Infrared (IR) Filter From Microsoft Lifecam Studio

The Lifecam Studio is a great camera for day time surveillance. But with the infrared (IR) filter in place, using IR illumination will not help with night time recording. This instructable will show you how to remove the IR filter.

Step 1:

Pry off the outer plastic bezel. It is held on with double-sided tape. Remove the remnants of the tape. You should now see 2 small screws.

Step 2:

Remove the 2 screws, then the inner plastic bezel should slide out.

Step 3:

Use needle-nose pliers to unscrew (counter-clockwise) the barrel of the lens assembly.

Step 4:

Don't get any dust on the image sensor!

Step 5:

This is the IR filter on the back of the lens assembly.

Step 6:

Using an utility knife blade, make a small "V" shaped notch in the barrel of the lens assembly.

Step 7:

Then using the tip of a utility knife blade, pry away the IR filter. There is another lens right behind the IR filter, be careful not to scratch the lens.

Step 8:

The IR filter is extremely thin glass, and will probably crack, but it is not needed any more.

To re-assemble the camera, follow the dis-assembly steps in reverse, but stop before replacing the inner bezel. At this point you will need to adjust the position of the lens assembly. To do that, you will need to plug the camera into a computer, and start some application that will let you see the video output from the camera.

Disable auto-focus in the application, then using the manual focus adjust in the software, set it to somewhere in the middle of the focus range. Now point the camera at some object about 10ft away, and using the needle-nose pliers, turn the lens assembly until the picture is in focus. This will allow the auto-focus mechanism, once everything is back together, to focus on objects both far or close.

Step 9: Testing Light Sensitivity With 48 LED Infrared Illuminator

Removing the IR filter will greatly diminish the camera's ability to render color in scenes illuminated by daylight or incandescent lighting. Color rendition under fluorescent lighting should still be acceptable.

The night shot above is illuminated by a small 5 watt 48 IR LED panel.
