For Sensor Calibration and Continuous, High-Throughput Applications

Energetiq LDTLS® compact light sources let you break free from wavelength constraints for quick, repeatable, and precise measurements across the broadest spectrum.

Built around our Laser-Driven Light Source (LDLS™) technology, the Laser-Driven Tunable Light Source (LDTLS) gives you access to a wide wavelength range of tunability, high spectral resolution, and an extremely long lifetime with the convenience of fiber-coupled output. The LDTLS features a precision high-performance monochromator for accurate wavelength selection and repeatable light output from 170 nm to 2500 nm.

  • High spectral radiance for the highest output flux (300 nm – 1100 nm)
  • Up to 3 mW output power (wavelength dependent ~6.5 nm bandwidth and 1500 µm fiber)
  • Broadest spectrum: 170 nm – 2500 nm
  • Low noise, high stability
  • 200 nm/second scan speed
  • 10,000+ hours of operation
