SPEC SPEED+ / SPEC SPEED+ UV

• Wavelength range: 200-400 nm
• Optical Resolution: 0.5 nm
• Fast acquisition: 2857 spectra/sec (full spectra)
• 1800 grooves/mm grating blazed at 250 nm
• Back thinned 2048 CCD array detector
• LighScan+ software included

Covering the entire UV range. the SPEC SPEED+ UV offers high acquisition rate and the optimized optical configuration with a 25 µm slit, a 1800 grooves per mm grating blazed at 250 nm allows also a great resolution of 0.5 nm. The detector is an Hamamatsu back thinned CCD array with 2048 pixels with 1 mm pixel height for high sensitivity. Software LightScan+ allows the best flexibility for time and sensitivity control of the spectrometer.

The spectra obtained with a Mercury lamp is found below. The great resolution is proven in the detail spectra of the separation between peaks 365.015 and 366.328nm. Even a "shoulder" in the 365.015 that is related to the 365.484nm peak can be observed.
