Modifying Logitech 9000 pro web camera into infrared mode
The considered webcam - Logitech 9000 PRO
Back shield removed.
Same as above.
Front panel. The lens are on the left.
Unscrewed lens. The IR filter is the round, transparent surface. It is glued with epoxy. It was removed by cracking into small crumbs with some sharp toy. Be careful not to touch the lens, which is just 1 mm under the filter.
A comparison - IR view by Logitech9kPRO vs standard view
