L-Band ASE Broadband Light Source

Amonics L band ASE light source features high output power, very wide spectral range and high stability against temperature change. It is available in both benchtop and module casings.

The benchtop version incorporates a user-friendly front panel housing with a LCD monitor display, key switch, power control knob and optical connectors. RS232 or Ethernet computer interface is also equipped.

The OEM module version is an ideal building block for OEM system integration, especially in fiber optic sensing and optical tomography applications. It requires a single +5V power supply only.
