Thermally Tunable Fibre Bragg Grating

The OETFG-300 allows you to fine-tune the central wavelength of a fibre Bragg grating by using a thermo-electric cooler (TEC). The grating can easily be replaced for a greater flexibilty in the central wavelength.
The device is available in turn-key version, including a chamber box, a TEC, a heat sink and a temperature controller. An OEM version is also available for customer who already own a temperature controller. The OEM version only includes a chamber box, a TEC and a heat sink.

Features:

• Custom FBG specifications
• Simple and easy to operate
• Work for any type of fibre Bragg grating
• Turnkey solution available

Applications:

• Spectroscopy
• Optical sensing
• Laser technology
• Testing and laboratory experiment
