What type of light source does the DFB Optical Spectral Engine (OSE3) use?

The OSE3 uses a DFB (Distributed Feedback) laser diode architecture, providing narrow-linewidth, spectrally stable output at a fixed wavelength.

What is the key advantage of a DFB-based spectral engine?

DFB laser diodes offer single-mode, narrow-linewidth emission with excellent wavelength stability, making the OSE3 ideal for applications requiring high spectral resolution and wavelength accuracy.

What applications is the OSE3 designed for?

The OSE3 is suited for gas sensing, absorption spectroscopy, and other applications where a stable, narrow-linewidth laser source is required at a specific wavelength.
