TLS wavelength tunable monochromatic light source

The Tunable Light Source (TLS) are pre-aligned, preassembled illumination systems capable of outputting monochromatic light from 200-2500 nm. This is a complete plug and play system and includes TLS-C1 software.

TLS is composed of Zolix light source and spectrometer. It is very convenient for the users who want the flexibility of a modular design and the simplicity of an integrated system.

  • Good light source stability, better than 0.5%
  • High integration, system integrated in the optical plate, it is easy to transport and protect the stability of optical path
  • Light path is optimized to achieve maximum light output efficiency
  • The output bandwidth can be adjusted continuously, 0.1-30nm
  • Software can control any wavelength adjustment and the time delay
  • USB2.0
