Monochromatic tunable light sources

TLS-C1 Wavelength Control Software

From 200 nm to 2400 nm

Tunable Light Sources (TLS) are pre-aligned, pre-assembled illumination systems capable of outputing monochromatic light from 200 nm to 2400 nm. These plug and play systems deliver precise, high-intensity, and spectrally adjustable illumination for a wide range of applications.

What sets us apart?

TLS are composed with monochromators and high power ARC lamps from our supplier Zolix Instruments or Laser Driven Light Source (LDLS) lamps from our partner Hamamatsu. Several monochromators options are available (internal shutter, motorized slits, additional entrance and exit ports) and also multiple output accessories (fiber/bundle adapters, collimator, integration sphere and sample chamber). It is very convenient for the users who want the flexibility of a modular design and the simplicity of an integrated system.
