The company’s product lineup of IR-LEDs splits in three categories, conventional LEDs made by Liquid Phase Epitaxy (LPE), transparent type LEDs and reflection type LEDs made via Metal Organic Chemical Vapor Deposition (MOCVD).
The output of reflection type LED is enhanced with a mirror layer formed under the light emission layer to reflect the light beam upward. Reflection type LEDs have been used as parts of photoelectric sensors for industrial equipment and other devices.
Now, SDK upgraded its technology, adding “Double Junction Reflection Type LED” and “P-up Reflection Type LED” to its product lineup of IR-LEDs.
Double Junction Reflection Type LEDs have two light emission layers and output nearly twice as much light as conventional reflection type LEDs. This makes them suitable for uses such as biometric sensors, surveillance or security cameras, virtual reality, and sensors for automotive equipment.
P-up Reflection Type LEDs have a polarity reversed from that of N-up structure, which is the mainstream structure of conventional reflection type LEDs. Those IR-LEDs are produced using an LPE process
