John H. Burnett, Eric C. Benck, Simon G. Kaplan, Erik Stover, Adam Phenis
Measurements of the index of refraction of a sample of high-quality, single-crystal germanium using the minimum deviation refractometry method are presented for temperatures near 22 degC and for wavelengths in the range 2 micron to 14 micron. The standard

Refractive index measurements of Ge

Author(s)
John H. Burnett, Simon G. Kaplan
A program has been started at NIST to make high-accuracy measurements of the infrared (IR) index properties of technologically important IR materials, in order to provide the IR optics community with updated values for the highest-quality materials now

Infrared Optical Properties of Materials

February 24, 2015
Author(s)
Simon G. Kaplan, Leonard M. Hanssen, Raju V. Datla
This document describes the Fourier Transform Infrared Spectrophotometry (FTIS) Facility at the Sensor Science Division (SSD) of the National Institute of Standards and Technology (NIST) to provide the infrared optical properties of materials (IROPM)

Chapter 4: Fourier transform methods

April 25, 2014
Author(s)
Simon G. Kaplan, Manuel A. Quijada
Chapter 4 describes the use of Fourier Transform Spectrometers (FTS) for accurate spectrophotometry over a wide spectral range. After a brief exposition of the basic concepts of FTS operation, we discuss instrument designs and discuss their advantages and

Calibration of IR Test Chambers with the Missile Defense Transfer Radiometer

Simon G. Kaplan, Solomon I. Woods, Adriaan C. Carter, Timothy M. Jung
The Missile Defense Transfer Radiometer (MDXR) is designed to calibrate infrared collimated and flood sources over the fW/cm2 to W/cm2 power range from 3 m to 28 m in wavelength. The MDXR operates in three different modes: as a filter radiometer, a

Initial testing of a Si:As blocked-impurity-band (BIB) trap detector

Author(s)
Solomon I. Woods, Simon G. Kaplan, Timothy M. Jung, Adriaan C. Carter, James E. Proctor
We discuss the design, construction, and initial test results of a Si:As blocked-impurity-band (BIB) trap detector. The trap consists of two rectangular BIB devices configured in a v-shaped geometry. This trapping geometry is designed to ideally yield a
