LED/SLED Broadband High Stable Light Source (OS)

Relying on high accuracy automatic power control (APC) and automatic temperature control (ATC) techniques, the LED/SLED broadband light sources deliver stable output power in both short term and long term. These light sources can work at CW, internal modulate, and external modulate modes.

LED offers low power broadband light source. SLED offers relatively higher output power. These LED and SLED work at wavelength range of 1310nm, 1480nm, 1550nm and 1620nm.
