NM/MIN Sets the scan rate in nm/min to 0.01 nm/min resolution with units nm/min
?NM/MIN Returns present scan rate in nm/min to 0.01 nm/min resolution with units nm/min
Grating Control Commands:
GRATING Places specified grating in position to the wavelength of the wavelength on the
present grating. Up to nine (9) gratings are allowed on three (3) turrets. This
command takes a grating number from 1 - 9. IMPORTANT NOTE: This command
assumes that the correct turret is specified by the TURRET command. For example,
using grating numbers 1, 4 and 7 will place the first grating on the installed turret into
that position and call up the parameters for the grating number specified.
?GRATING Returns the number of gratings presently being used numbered 1 - 9.
?GRATINGS Returns the list of installed gratings with position groove density and blaze. The
present grating is specified with an arrow.
TURRET Specifies the presently installed turret or the turret to be installed.
e.g., if installing the second turret, issue the command 2 TURRET to insure using the
correct parameters.
?TURRET Returns the correctly installed turret numbered 1 - 3.
The following command is used for grating installation by Acton part number:
INSTALL Installs new grating parameters into the non-volatile memory of the SP-2300i
monochromator. Uses the part number of the grating to specify the parameters.
e.g., 1-120-500 5 INSTALL places a 1200 g/mm grating blazed at 500 nm into the
second grating position on turret number 2.
The following commands are used for grating installation by grating parameters:
SELECT-GRATING Specifies the grating number to be installed 1 - 9.
G/MM Specifies groove density of grating to be installed in g/mm.
e.g., 1200 G/MM
BLAZE Specifies the blaze wavelength and units of the grating to be installed with 7
characters of the user’s choice. Unlike other commands, this command is issued
before the parameters. After the command is issued, the SP-2300i responds with ““ .
Seven characters are then entered (these may be numbers, letters, spaces or special
characters).
UNINSTALL Used to remove a grating and its parameters from the SP-2300i non-volatile memory.
Diverter Control Commands:
EXIT-MIRROR Designates the exit diverter mirror to receive the diverter control commands. This
command is for Acton SP series monochromators that can accept two diverter
mirrors. The SP-2300i monochromators will accept this command but it is not
required in these monochromators.
ENT-MIRROR Designates the entrance diverter mirror to receive the diverter control commands.
This command is for Acton SP series monochromators that can accept two diverter
mirrors. The SP-2300i monochromators will not accept this command.
FRONT Moves the designated diverter mirror to position the beam to the front port position.
SIDE Moves the designated diverter mirror to position the beam to the side port position.
?MIRROR Returns the position of the designated diverter mirror with the responses “front” and
“side”.
?MIR Returns the position of the designated diverter mirror with the responses 0 for front
and 1 for side.
