BRIDGEWATER, N.J., May 5, 2008 -- Hamamatsu Corp. said its new chip-on-board-type illuminance sensor, the S10604, displays spectral response with a sensitivity close to that of the human eye because of its reduced sensitivity to infrared light.

The miniature S10604 photo IC (integrated circuit) diode is an RoHS-compliant sensor ideal as an energy-saving sensor for large-screen TV brightness control, as a backlight dimmer in LCDs on cell phones, and in other applications where the level of the ambient light is measured, the company said.

The S10604's miniature package (2.0 mm x 1.25 mm x 0.8 mm) saves space in equipment where component assembly space is critical. According to Hamamatsu, the S10604 is the same size as typical chip resistors, lending itself to pick-and-place operation during mass production of equipment without the need for special assembly apparatus.

The S10604 circuit was designed to reduce effects from infrared LED light at 940 nm, light usually used for remote control tasks, which causes unwanted effects. In addition, the S10604 features minimal color temperature error. Output variations are minimized when detecting light of the same brightness, such as light from a fluorescent lamp and incandescent lamp.
