Chapter 4 Installation
NOTE:
Kurios is supplied with a 115 V power cord for use in North America only. For all other applications, use an
IEC 320 compatible power cord fitted with a plug appropriate for your particular power socket. Make sure that the
line voltage rating marked on the rear panel agrees with your local power supply and that the appropriate fuses are
installed. Changing of the main fuse can be done by the user.
4.1. Connections
Controller Connection:
Connect the special cable provided between the KURIOS controller and the optical head before powering
on the KURIOS controller.
PC Connection:
If using the software interface or command line for controlling the filter, connect the provided USB cable
from the back of the KURIOS controller to the PC.
TRIGGER IN:
If using the externally triggered SEQUENCE or ANALOG modes, connect a 5 V TTL signal to the
TRIGGER IN BNC connector on the KURIOS controller front panel.
TRIGGER OUT:
The back panel TRIGGER OUT BNC connector will output a 0 V or 5 V voltage when wavelength
switching. By default, the trigger switches low to high while tuning is occurring. The TRIGGER OUT
waveform can be set by the command line or in software.
ANALOG IN:
If using the ANALOG modes (which require internal or external triggering), connect a 0 – 5 V signal to
the ANALOG IN BNC connector on the KURIOS controller front panel.
4.2. Optical Head
The KURIOS optical head may be used in both directions, i.e. the input beam can enter from either the front or back
face of the head. Since the filter is polarization sensitive, the polarization of the input beam needs to be aligned with
the engraving on the optical head for maximum transmission. The transmission axis is denoted by the T-AXIS
marking on the head. Note that the polarization is rotated by 90° through the device. Both the front and back faces
of the KURIOS-WB1(/M), KURIOS-VB1(/M), and KURIOS-XE2(/M) optical heads have four 4-40 internal threads
and SM1(1.035"-40) internal threads, which are used for mounting Thorlabs’ 30 mm cage systems and lens tubes,
respectively. The optical head and faces of KURIOS-WL1(/M) and KURIOS-XL1(/M) have four 4-40 internal threads,
which are compatible with Thorlabs’ 60 mm cage systems, as well as SM2(2.035"-40) interal threads for lens tube
mounting.
For tunable filters working in the VIS range, a premium shortpass filter with a cut-off wavelength of 750 nm is
included in the package and pre-installed in a lens tube. There is a Ø1" premium shortpass filter included with the
KURIOS-WB1(/M) and KURIOS-VB1(/M), pre-installed in an SM1L03 lens tube. There is a Ø2" premium shortpass
filter included with the KURIOS-WL1(/M) and KURIOS-XL1(/M), pre-installed in an SM2L03 lens tube. The lens
tube with the mounted filter can easily be screwed on the tunable filter input port to block unwanted light above 750
nm, protecting the KURIOS filter from excessive NIR light illumination. Please refer to Thorlabs Item # FESH0750
for a detailed transmission spectrum.
