In a pinch the camera on a MacBook pro can be used to detect presence of IR light. Here's light from a 10Gbase-LR xenpak: http://www.majhost.com/gallery/kl/Macbook/macbook-laser-camera.jpg It's easier to see when previewing in real time than in the static picture but it does require careful aim. - Kevin
Most 'cell phone' cameras also detect IR. Handy to verify that A/V equipment "Remotes" are working. --Michael
