Display of wavelength
0.1nm increments

Setting of wavelength
The start and end wavelength in scanning can be set in increments of 1nm.
With the GOTO WL command, wavelength can be set in increments of 0.1nm

Wavelength accuracy
±0.3nm (at slit width of 0.2nm) in ultraviolet/visible region
±1.6nm (at slit width of 1.2nm) in near-infrared region
Automatic wavelength correction is possible.

Wavelength repeatability
±0.1nm in ultraviolet/visible region
±0.4nm in near-infrared region

Wavelength scanning speed
In the case of wavelength setting by:
GOTO WL command: 2100nm/min
FAST 1600nm/min (with 2nm sampling interval)
FAST 700nm/min
MIDDLE 200nm/min These are the speeds when scanning with 0.5nm sampling interval.
SLOW 100nm/min
SUPER SLOW 50nm/min

Switching of the light sources
The light sources are switched automatically in conjunction with wavelength scanning. The wavelength at which the light sources are switched is selectable in the range of 282nm to 393nm in 0.1nm increments.
