IF-E92: Plastic Fiber Optic Blue LEDs

The IF-E92A and IF-E92B are blue LEDs housed in a "connector-less" style plastic fiber optic package. The IF-E92A contains a Silicon Carbide die with a spectral output peaking at 430 nm and the IF-E92B die is made from Gallium Nitride peaking at 470 nm. The device package features an internal micro-lens and a precision-molded PBT housing to ensure efficient optical coupling with standard 1000µm core plastic fiber cable.

Application Highlights

These LEDs are low-cost alternatives to other light sources for producing a narrowband blue light output that can be efficiently coupled into a fiber cable. They can be used in a variety of sensor and display applications that require a narrowband optical light source whose intensity can be easily adjusted or modulated without changing optical spectrum. When combined with red and green LEDs the IF-E92A and IF-92B provide an RGB source for generating white or multicolored light. Applications include process control for color identification/separation and demonstration of wavelength division multiplexing for education purposes. The IF-E92A and IF-E92B are also capable of digital data rates of 1 Mbps and 800 kbps respectively. The electrical drive circuit design is the same as that of other LEDs, making the IF-E92A and IF-E92B cost-effective ligth sources in a variety of analog, digital sensor and lighting applcations.
