Vacuum Ultraviolet Fluorescence Excitation System MVUV-03
 
This vacuum ultraviolet fluorescence excitation system uses a VUV-compatible spectrometer to make vacuum ultraviolet light (130 nm to 200 nm) monochromatic, irradiates the sample with it, and guides the fluorescence from the sample (300 nm to 700 nm) into an optical fiber.

■Specifications

Excitation light source unit
Light source Deuterium lamp (30 W)
Spectrometer KV-200 nitrogen-purged spectrometer
Reciprocal linear dispersion Approx. 2 nm/mm
Measurement wavelength range 130 nm to 200 nm
