Measurement Services

BRO now offers measurements of several optical properties:

Measurement of a material’s reflection or transmission properties as a function of wavelength

  • UV, Visible, NIR and IR Transmittance
  • UV, Visible, NIR, and IR Reflectance
  • UV, Visible, NIR, and IR Absorptance/Emittance
  • UV, Visible, NIR, and IR Transflectance
  • Dispersive and FTIR Modes in the IR
  • Total, Specular and Diffuse Modes in the UV, Visible, NIR and IR
  • Variable Angle Transmittance and Reflectance in the UV, Visible, and NIR
  • Cryogenic Transmittance


  • Agilent Cary 500E Grating UV-Vis-NIR Spectrophotometer with Labsphere TM Spectralon TM side-looking & down-looking integrating spheres
  • Agilent Cary 5000 Grating UV-Vis-NIR Spectrophotometer with Universal Measurement Accessory (UMA) for variable angle, ABSOLUTE transmittance & reflectance for incident angles from 5° to 85°
  • Agilent Cary 7000 UV-Vis-NIR Grating Spectrophotometer
  • Perkin-Elmer 983GTM Grating IR Spectrophotometers with Specular & Variable-Angle Reflectance Accessories
  • Nicolet iS10TM Fourier-Transform – IR Spectrophotometer with Labsphere TM Infragold TM integrating sphere
  • Perkin Elmer 983G TM IR Grating Spectrophotometer
  • Nicolet 560TM FT-IR Spectrophotometer


A class of spectrophotometry that measures fluorescence, the phenomenon in which light incident on a material at a given wavelength, usually in the ultraviolet or visible spectral range, causes that material to radiate light at longer, less energetic wavelengths.


  • Agilent Eclipse UV-Vis-NIR Grating Fluorometer


Measurement of surface features including surface roughness and step height. Commonly employed in optical fabrication, substrate preparation and thin-film development.


  • MicromapTM 512 Non-Contact Optical Profilometer


Haze measurements
Measurement of haze, clarity and visual transmittance.


  • BYK-Gardner Haze-Gard Plus and other glossmeters


Luminous intensity
Measurement of optical flux per angle.


  • Type A Goniophotometer featuring 0.1° horizontal/vertical resolution.
  • Calibrated detector for photometric or radiometric measurements.
  • Data provided per IESNA: LM-63-2002 or .txt file.
  • Useful engineering diagnostic for source evaluation.


BRO also offers

  • Ambient/controlled/extreme environments for exposure & testing to MILSPEC/ASTEM/ANSI/ISO and other standards
  • NIST/NRC/NPL/VLSI traceable standards
  • Consulting in bulk and thin-film materials
  • Very large sample measurement by arrangement
