Gradient Filter Carriage
sunrise
gradient filters cannot be used with a standard or 6 Filter
instrument.
The
sunrise
gradient filter carriage is fitted with a gradient filter that allows the
selection of any wavelength from 400 to 700 nm.

The gradient filter carriages are calibrated by the manufacturer and each one is
unique.
Note
When another gradient filter is inserted into the instrument, the instrument
must be re-calibrated. This re-calibration procedure can only be
performed by the manufacturer or by a service engineer.
When a wavelength is selected, the entered wavelength is compared against the
calibration table. The filter carriage is moved the required distance, so that the
required section of the gradient filter is in the light beam.
Gradient filters can only be used with the
sunrise
tuneable wavelength
Absorbance Reader.
