The narrow-band light is used in the measurement of the optical properties of materials and in the characterization and calibration of optical instruments. Historical calibration sources used more conventional lamps in the past (e.g., quartz-tungsten halogen lamps) in combination with conventional monochromators. This output from the monochromator suffers from low power and low brightness which prevents this approach from being used in many advanced applications. Combining recently developed sources and spectral filters, e.g.  laser-driven white-light sources (supercontinuum (SC) source) and laser line tunable filters (LLTF) (SC-LLTF), the emitted flux is increased several orders of magnitude over conventional lamp-monochromator systems; the increased flux available opens up many radiometric and photometric applications not possible with conventional systems."

WHITE PAPER - WIDELY TUNABLE FILTER
TECHNOLOGY & MEASUREMENT OF CRITICAL SPECIFICATIONS
By Daniel Gagnon and Laura-Isabelle Dion-Bertrand

The out-of-band rejection and the optical density (OD) are two critical specifications of tunable filters. Unfortunately, these properties are often misinterpreted and their definitions tend to differ from one manufacturer to another. End users need to be careful when looking over the specifications of a filter. Also, the measurement of these properties for customers can be laborious. One needs to have sensitive instruments with a high dynamic range, a wide spectral range and a high power source. In this white paper, clear and rigorous definitions of the out-of-band rejection and the OD of widely tunable filters are presented, and the steps and instrumentation needed to accurately measure those specifications are exposed.
