1. A 400 nm to 2500 nm Absolute Spectral Radiance Comparison Using Filter Radiometers
Published: 10/1/1998
Authors: Howard W Yoon, Bettye C Johnson, D Kelch, S F Biggar, P R Spyak
Abstract: An integrating sphere source developed by MTL Systems, Inc. was calibrated for them by a commercial standards laboratory traceable to the National Institute of Standards and Technology (NIST), resulting in values of spectral radiance in the 400 nm to ...
