Paper Abstract

The Absolute Radiometric Calibration Facility (ARCF) at TNO operates a unique optical scatter measurement set-up for the characterization of optical components for space applications and has been recently refurbish to extend the working wavelength domain from UV/VIS/NIR to SWIR, making accurate measurements possible in the entire 240-2400 nm range. A second extension currently being performed is the addition of an optical parametric oscillator (OPO) laser light source, tunable over the same wavelength range. The increased light levels made possible by this new source will improve the signal-to-noise-ratio (SNR), significantly reducing measurement time and potentially further increasing the measurement accuracy. In this article we will present the challenges encountered in expanding such a setup to the SWIR and their solutions, show the new capabilities of the setup and explain the possibilities of using tunable pulsed OPO lasers in calibration applications.
