Tunable sources & filters
Tunable Monochromatic Light Sources
Broadband lamp illumination combined with an Omni monochromator and order-sorting optics. Choose the compact two-grating TLS2 or the three-grating TLS3S, then match the lamp, grating and output coupling to the measurement.
Best suited to
Scanning spectral response, excitation wavelength and wavelength-dependent optical properties.
Selecting a configuration
Specify the wavelength interval, required bandwidth and light level at the sample. Published coverage is configuration dependent; UV, visible and infrared ranges require different lamps, gratings and optics.
Measurement & configuration
- Manual bandwidth adjustment; motorised wavelength selection.
- Free-space, fibre or integrating-sphere output selected for the experiment.
- Xenon, halogen, infrared-emitter and reviewed laser-driven source configurations.

|---|---|---|---|
| TLS2 / short-wave | 0.15–10 nm | ±0.2 nm | 0.1 nm |

Representative published grating configurations, with accuracy/repeatability referenced to the 435.8 nm line. Bandwidth depends on grating and slit setting; these are not simultaneous full-range specifications.
Configuration note: TLS3S is the current configuration naming used alongside the TLS3 family. Lamp coverage is not a guarantee of constant output power. Confirm the lamp, grating, order sorting and detector together.
