Broadband Light Sources


Broadband Light Sources


EXALOS provides highly customizable benchtop instruments in various form factors for research, development, production and testing environments. Our benchtop instruments can be configured with up to eight SLEDs for ultra-broadband light sources.

Our Broadband Light Sources can either have individual optical outputs for each SLED or can be configured to have one common output where the spectra of the individual SLEDs are combined. In the long-wavelength range EXALOS can offer an ultra-broadband 350-nm light source from 1270 to 1620 nm with more than 40 mW of optical output power.

In the short-wavelength range EXALOS can offer an ultra-broadband 170-nm light source from 750 to 920 nm.

A compact turn-key system. The electro-optical performance depends on the product code.

Optical output might be realized either with a single-mode fiber or with a polarization maintaining fiber, depending on the chosen SLED module.

The EBS30 and EBS40 series provide remote control through electrical analog and digital control signals and modulation capabilities up to 50 Hz. Optionally a low degree of polarization (DOP) can be achieved using fiber depolarizers. Furthermore, spectral shaping through custom optical bandpass filters can be realized.
The EBS is designed for ultra-high resolution Optical Coherence Tomography.
