​AST/ASTN Series Wavelength Tunable Light Sources



- Variable narrowband light output selection from UV (200nm) to Near IR (2.2µm)
- Computer controlled via standard RS232 interface
- Scans in both directions and in nanometers, Angstroms, microns, wave-numbers, 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' broad b and 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 monochromator can be coupled.



AST-XE series: ASB-XE-175 [175W Xenon light source based model]

AST-W030/ASTN-W series: ASB-W030 [30W Tungsten-Halogen or ASBN-W High Power Tungsten-Halogen light source based model]

ASTN-D series: ASBN-D130/ASBN-D230 [30W single or dual deuterium light source based model]

ASTN-Dx-W series: ASBN-Dx-W series [single or dual deuterium + High Power Tungsten-Halogen Hybrid light source based model.]

Band-pass region and width is controlled by selection of monochromator slit size and gratings
