​AST/ASTN Series Wavelength Tunable Light Source systems



- Variable narrowband light output selection from UV (200nm) to Near IR (2.2µm)
- Computer-controlled via standard RS232 interface
- Scans in both directions and nanometers, Angstroms, microns, wavenumbers, or eV
- May be configured for optimal fiber optic illumination
- Modular design allows for reconfiguring
- Attenuation control
- Couples to Spectral Products equipment



Simple and Flexible

Spectral Products has a tunable light source to meet your needs. Each model is based on our popular CM110 dual grating, 1/8-meter monochromator, paired with one of Spectral Products' broadband light sources. When purchased together as a tunable light source, you get pre-adjusted coupling and the best-matched grating(s) preloaded. Depending on the requirements for better resolution/accuracy, other DK240 or DK480 monochromators can be coupled.
