Hamamatsu Corp. has introduced a silicon photodiode that is sensitive to the blue, green and red spectra. The company says that the S9032-02 has a spectral response range close to that of the human eye and no sensitivity in the near-IR, making it useful for design into LED backlight systems for LCDs and color-measurement instruments such as spectrophotometers. It has a spectral response range from 400 to 540 nm on the blue channel, 480 to 600 nm on the green and 590 to 720 nm on the red, and achieves typical peak sensitivity of 0.18 A/W at 460 nm, 0.23 A/W at 540 nm and 0.16 A/W at 620 nm in the blue, green and red, respectively. It comes in a small, surface-mount package. Operating temperature is ±25 to +85 °C.
