This page contains information about the McPherson Monochromator.
Basic information
We have in our setup the McPherson 302 .2 meter scanning monochromator. Where the wavelength can be selected using the setting dial on the device or using the build in motor. To control this build in motor we do not have the controller but we will use an Arduino to control the motor which gives us more control over changing wavelengths within our measurement run.
Motor controls
To use the build in motor there are two connectors to consider, one directly going to the stepper motor (Parker LV231-02-10)and one going to the limit switches. The connection on the back of the monochromator connecting the limit switches is shown below.
Pin 5 and 6 are connected to one another via a blue cable, this can be used to see if you connected the connector right side up. Pin 11 and 15 is the lower wavelength switch, the front of the monochromator. Pin 13 and 16 is the higher wavelength switch, the back of the monochromator. These switches are always passing through a signal and when pressed break connection.
