MUNICH, Sept. 20, 2016 — Osram Licht AG has announced the SFH 2240 L large-area photodiode to save on mounting height in the design of heart rate sensors.
The device sharply cuts off wavelengths above the visible spectral range. In the IR range, the relative sensitivity is only 5 percent of the maximum value at 620 nm. Green light sensitivity is high, therefore good signal quality can be achieved for pulse measurements with green light even at a low operating current.
It can be flush-mounted on the printed circuit board with longer leads, ensuring secure mounting and reliable solder points. The component also features spectral sensitivity specially designed for measuring heart rate.
