Optical measurement

Detection, control and monitoring of ultraviolet, visible and infrared radiation

Calibration and measurement of ultraviolet (UV), visible and infrared (IR) radiation are required by many industries, including pharmaceuticals, chemicals, aerospace, defence, food, textiles and printing. Many health and safety applications, such as signalling, photobiological safety evaluation and medical diagnostics, rely on accurate optical measurements. We also support the optical industry in the design and production of optical components and coatings.

NPL has the in-house expertise and facilities to provide a comprehensive range of calibration and measurement services, including reflectance, transmittance, colorimetry, photometry, spectroradiometry and detector response.


We offer consultancy, training and research on all aspects of optical radiation metrology, and have a comprehensive range of calibration and measurement services for the production, detection, control and monitoring of UV, visible and IR radiation.
