    5.1.1. Bandwidth KURIOS has four bandwidth modes: WIDE, MEDIUM, NARROW, and BLACK. Pressing the bandwidth button on the controller cycles through the modes in the following order: KURIOS-WB1(/M) : WIDE, BLACK. KURIOS-WL1(/M) : WIDE, BLACK. KURIOS-XE2(/M) : NARROW, BLACK. KURIOS-XL1(/M) : NARROW, BLACK.

  • Page 29: Chapter 6 Technical Terminology

    Technical Terminology 6.1. Bandwidth Thorlabs’ KURIOS ® tunable filter defines the passband bandwidth as the Full Width at Half Maximum (FWHM). This is the spectral width between the two points where the filter’s transmission reaches half of the peak value. The KURIOS filter’s bandwidths are dependent on wavelength and optical design, and therefore different models and...

  • Page 30: Tuning Accuracy

    Kurios ® Liquid Crystal Tunable Filters Chapter 6: Technical Terminology 6.7. Tuning Accuracy The difference between the wavelength setting and the actual filter output center wavelength is defined as tuning accuracy, and is measured in terms of FWHM at the current set wavelength. KURIOS tunable filter output center wavelength accuracy is corrected to within ±FWHM/10.
