Commercial remotes have been developed using ultrasound, radio, and IR, but the low price and high reliability of IR remotes have allowed them to dominate the consumer market. Ultrasound remotes can be distinguished by screens or grills which form the ultrasound ports. IR remotes usually have either a dark red plastic IR window, or an exposed IR diode, which appears as a clear plastic bulb emerging through the end of the device. Radio remotes generally broadcast through their plastic cases and have no obvious window or port. Programmable IR remotes, such as the One-for-All model used here, retail at department stores for ∼$20.

Catalog No. 276-1099, Radio Shack, ∼$6 each. These cards respond to IR from 0.7 to 1.3 μm. During use, they must be periodically "recharged" with daylight or light from a fluorescent lamp, for ∼10 s.

Potential filters can be tested for IR transmission by seeing if IR remotes can control appliances through them, and observing (with human eyes) if visible is transmitted. The following have been found to make suitable IR filters for these experiments: (A) the front piece of many IR remotes; (B) cobalt blue glass, which transmits IR and blue, but a red metal filament does not generate much blue, leaving only IR; (C) the overexposed and developed color film strips usually produced from each roll of photographic film; (D) stacked blue and red Lee Filters, which together transmit IR but not visible. These filters can obtained in 0.6 by 0.6-m sheets from Jacksonville Stage Lighting, 640 N. Lane Ave., Jacksonville, FL 32254. Transmission spectra packaged with small filter samples are available. More than 100 different types of filters available for <∼$10 each, which when cut into pieces make 5 X 5-cm filters for ∼7cents each. We use 20 X 20-cm color filters in exercises in basic astronomy labs where students investigate the light which passes through their closed eye lids.
