LD 271 Series

osram

The LD 271 series from OSRAM Opto Semiconductors is a lineup of 5mm infrared emitters operating at a wavelength of 950nm. These components are widely used in applications requiring precise distance measurement or object detection in the near-infrared spectrum. If you're working on anything involving non-contact temperature sensing, proximity detection, or optical communication over short distances, these emitters are a go-to choice. One thing worth noting is their efficiency in low-light conditions. The 950nm wavelength is well-suited for applications where ambient light is a factor, such as in automotive night vision systems or industrial safety equipment. Engineers tend to reach for this series when they need reliable, low-power emitters that can operate effectively in challenging lighting environments without being detected by the human eye. Another practical application is in medical devices where non-invasive monitoring is required. For instance, these emitters can be used in pulse oximeters to measure blood oxygen saturation levels by detecting the absorption of infrared light through the skin. Their compact size and robust performance make them ideal for integrating into por
