Agilent Certified diffuse reflect std WL + WN 9910081100

The Agilent 9910081100 is a certified PTFE diffuse reflectance standard intended for calibration and verification of diffuse-reflectance measurements on UV‑VIS‑NIR spectrometers and integrating-sphere systems. It provides a high, spectrally flat reference across the ultraviolet through shortwave‑infrared region and is supplied with instrument-reference data to establish traceability. Typical uses include routine instrument qualification, method validation, and comparative reflectance measurements where a stable, NIST‑traceable diffuse standard is required.

Key Features:

• Material: PTFE diffuse reflectance standard (spectrally flat PTFE)
• Typical reflectance value: ~99%
• Spectral range of certified data: 250–2500 nm
• Reflective area diameter: 1.25 inch (approx. 31.75 mm)
• Calibration data: Supplied complete diffuse reflectance data from 250–2500 nm in 50 nm intervals, directly traceable to NIST
• Physical mounting: Housed in a durable Delrin holder with protective cover

Advantages:

• Provides a high (≈99%) and spectrally flat reference to reduce wavelength-dependent bias in diffuse reflectance measurements
• Includes NIST‑traceable certification data (every 50 nm across 250–2500 nm) to support instrument calibration and regulatory/compliance records
• Compact, Delrin‑holder packaging protects the standard and simplifies handling and repeatable positioning during routine use
