NIST Traceable NIR Wavelength Reference, Transmittance

(RM-NIR) NIR wavelength reference, Transmittance, NIST Traceable

NIST Traceable NIR Wavelength Reference is used with a quartz cell in either Transmittance or Transmittance/Transflectance format. NIST Traceable with UKAS ISO 17025 accredited certificate of calibration. Its primary usage is in the assessment of wavelength scale accuracy in the NIR spectrum, with a usable range of 990nm to 2537nm. It is used with a filled near IR quartz cell that has been permanently heat sealed

The reference is used to validate the wavelength scale of a NIR spectrophotometer. With 13 certified peaks from 990 to 2537 nm that include some complex for instrument resolution evaluation.

The reference is available in two formats:

  • Transmittance: - 10mm optical pathlength with two clear windows (opposite windows to allow light to pass through the cell).
  • Transmittance/Transflectance - 5mm or 10mm optical path length, depending on orientation. In 5mm configuration, the rear window is mirror coated to provide reflectance optical return so pathlength is effectivly 10mm ( 2 x 5mm = 10mm).

Each reference set is supplied with full certification and traceability to NIST through SRM-2065. The reference material is produced and certified in our ISO Guide 34 and ISO/IEC 17025 accredited laboratory. The reference can also be recertified as required.
