Product Description

Transmittance Standards

Avian Technologies supplies a wide range of transmittance standards for both regular and customised applications in the UV-Vis-IR regions. Transmittance calibration is essential for assessing the dynamic range of detectors and optical systems and Avian Technologies’ years of experience and attention to detail will ensure your essential systems stay accurate and true.

A variety of sizes, specifications and options are available, so please contact Analytik for technical questions and pricing information. All transmittance calibration standards are traceable to NRC/NIST and paper-copy/digital calibration data is provided.

For transmittance wavelength calibration standards, please consult our Rare Earth Oxide Wavelength Calibration Standards page here.

Please see the Transmittance Standards sets available:
