Request InfoOptek Technology, Industrial Sensing & ControlOptek Technology Inc., a subsidiary of TT electronics, has developed a vertical-cavity surface-emitting laser (VCSEL) that uses lower drive currents to achieve the same power output as conventional infrared LEDs. The OPV330 series devices operate at 850 nm with a maximum forward peak current of 20 mA and a maximum reverse voltage of 5 V, over a temperature range of –40 to 85 °C. The company says that the devices’ high thermal stability makes them suitable for low-power-consumption applications such as battery-operated equipment. Other applications include noncontact position sensing,...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/23/2024PIN PhotodiodeThe VEMD2704 from Vishay Intertechnology is a silicon PIN photodiode that can be used with green LEDs for optical heart rate detection and red LEDs for pulse oximetry applications.
