Synopsis

Measure high-temperature reflectance with a precision instrument built for extreme conditions.

This technical report introduces a laser-based integrating-sphere reflectometer designed to determine absolute spectral reflectance of materials up to 2500°K. It combines a helium–neon laser, a sodium chloride-coated integrating sphere, and a sensitive detector for accurate results.

The book explains the core concepts, design choices, and error analysis behind the instrument. It also presents preliminary data for materials like thoria, graphite, and tungsten, along with methods for calibration, heating, and measurement in vacuum or helium environments.
  • How an integrating sphere enables precise, absolute reflectance measurements at high temperatures
  • Design details and practical steps for building and operating the reflectometer
  • Techniques for reducing background noise and ensuring accurate readings
  • Experimental results and discussion of material behavior under heat
Ideal for researchers and engineers who need reliable high-temperature reflectance data and a clear methodology for evaluating refractory materials.
