5.4. Description of Commands
5.4.1. *idn? or *IDN?– Hardware Information
Queries the optical head model, controller hardware and firmware versions.
Return:
THORLABS KURIOS-VB1 SN-xxxxxxxx HWx.x FWx.x CN-xxxxxxxx
where SN is optical head serial numbers; HW is controller hardware version; FW is firmware version; CN is the
controller serial number.
5.4.2. SP? – Filter Wavelength Range
Queries the range of wavelength that the filter optical head supports.
For VIS tunable filter return:
WLmax=730.000
WLmin=420.000
For NIR tunable filter return:
WLmax=1100.000
WLmin=650.000
where WLmax and WLmin are the maximum and minimum wavelengths that can be set.
5.4.3. OH? – Filter Features
Queries the features supported by the connected filter. The OH? command returns a 16-bit number which reports
the features and bandwidth modes supported.
Return:
OH=n
where n is a 16-bit integer. When converted into binary form, n has the following Boolean structure:
n = 0000 0000 0000 0000
The higher 8-bit represents the spectral range, with
0000 0001 = Visible
0000 0010 = Near Infrared
Other values are reserved for other future filter models.
The lower 8-bit represents the bandwidth mode supported, with
0000 0001 = Black (beam blocking)
0000 0010 = Wide bandwidth
0000 0100 = Medium bandwidth
0000 1000 = Narrow bandwidth
Other values are reserved for other future filter models. More than one mode may be supported, depending on filter
models.
NOTE:
For KURIOS-VB1 optical head, which is a selectable bandwidth visible filter supporting BLACK, WIDE,
MEDIUM, NARROW mode, then OH? returns 271 (= 0000 0001 0000 1111).
