Chapter 3 Description
3.1. Overview
A liquid crystal tunable filter consists of a series of liquid crystal cells and polarizers. The KURIOS Tunable Filters
are directly controlled by the bundled KURIOS controller. The drive voltages of the liquid crystal cells are calibrated
to provide a specific retardance for each cell. This combination of retardances, along with the polarizers used, result
in a bandpass filter in which the passband wavelength can be adjusted by varying the drive voltages. Special signals
are applied to optimize the response when switching between wavelengths (voltages for each cell). The filter is
internally temperature controlled for consistent performance and fast switching. Two passband wavelength ranges
are available. The KURIOS-WB1(/M), KURIOS-VB1(/M), KURIOS-WL1(/M), and KURIOS-XL1(/M) Tunable Filters
are designed for visible wavelength (VIS) operation. The KURIOS-XE2(/M) is designed for Near-Infrared (NIR)
operation. For VIS filters, a premium shortpass filter, cut-off wavelength at 750 nm, is included and is recommended
to be used at the incident side of the filter.
The KURIOS-WB1(/M), KURIOS-VB1(/M) and KURIOS-XE2(/M) optical heads have a clear aperture of Ø20 mm
and are internally SM1 (1.035"-40) threaded. SM1-threaded adapters can be used to mount lens tubes, filters, and
other optics on the head. In addition, these optical heads are compatible with Thorlabs’ 30 mm cage system. It can
also be post mounted using the 8-32 (M4) tapped holes located on the sides of the filter housing.
The KURIOS-WL1(/M) and KURIOS-XL1(/M) optical heads have a clear aperture of Ø35 mm and are internally
SM2 (2.035"-40) threaded. SM2-threaded adapters can be used to mount lens tubes, filters, and other optics on
the head through the screw threads. In addition, the optical head is compatible with Thorlabs’ 60 mm cage system.
It can also be mounted by standard posts using the 8-32 (M4) tapped holes located on the sides of the filter housing.
The full featured KURIOS controller is custom designed for the KURIOS optical heads. There are different modes
of operation and bandwidth. The passband wavelength can be controlled in normal manual mode, as well as
externally adjusted via an analog control signal or software. A complete software package is provided that accesses
all the functions of the KURIOS controller. In addition, a full command-line interface can be used for custom software
development. The KURIOS is also fully compatible with the command set of CRi VariSpec tunable filters.
