Starna standard is the most convenient and effective tool for spectral photometry measurement in the ultraviolet and visible regions, and can meet the strictest international requirements. The Starna standard originated from the National Institute of Standards and Technology (NIST) reference material in the United States and was included in ISO

Produced under the guidance of Guide 34 standard, which is globally recognized as the highest standard. The calibration process meets ISO standards

The relevant regulations of 17025. Starna is the only provider of UV/Vis standards recognized by the UK Royal Accreditation Service (UKAS). All Starna standards come with a lifespan guarantee, promising to recalibrate the standards within a maximum of two years.
