The
model FWT-92D reader is a dual wavelength photometer for readout
of the FWT Radiachromic Dosimeters. The LED digital display reads
directly in Optical Density (OD). The two wavelengths are 510 nm
and 600 nm and are used to cover the range of the Radiachromic Dosimeters.
The instrument is simple to use. The front panel controls are used
to setup the instrument for operation. The wavelength is selected
from the front panel switch and the dosimeter is placed in the holder
and lowered into the well. The 1/2 “ digital display shows
the Optical density to 2 or 3 decimal places.
The instrument uses bandpass filters, which have excellent long
term stability, for wavelength selection. The lamp has a long life
and is easily replaced.
Options include an RS232 output for computer interface and a set
of neutral density filters for checking the operation of the instrument.
