Abstract
Vertically aligned carbon nanotube array (VACNT) technology has enabled the development of near perfectly absorbing, planar radiometric detectors, manufactured using silicon micro-fabrication techniques. The technology has been applied to a range of new detectors. We will discuss the application of this technology to the development of a new generation of primary radiometric standards at NIST Boulder [1]. The goal is to develop small, portable, chip-based radiometric calibration systems, spanning the wavelength spectrum from the ultraviolet to the THz region, suitable for use with both coherent and incoherent sources.
Recent work to enhance the blackness of nanotube arrays [2], and the development of facilities to spectrally characterize their reflection will also be presented. Work describing a tabletop cryogenic radiometric standard will be presented.
The over-arching theme of this work is the development of primary radiometric calibration standards that are fast, compact and easy to use.
