New calibration standards and methods for radiometry and photometry after phaseout of incandescent lamps

在许多应用中，准确了解光源产生的光辐射的光谱辐照度是很重要的。因此，需要确保光谱辐射测量的SI可追溯性。几十年来，光谱辐射测量仪器的校准一直使用基于白炽灯的转移标准来实现。然而，由于白炽灯产品的逐步淘汰，它们的可用性正在减少。该项目旨在为紫外可见近红外（UVVISNIR）光谱范围内光谱辐照度单位的探测器转移提供充足且经济实惠的替代转移标准光源和替代程序。它还旨在围绕这一关键的辐射计量单位建立一个综合的欧洲计量基础设施。

It is important to have an accurate understanding of the spectral irradiance of the optical radiation produced by light sources in a multitude of applications. Therefore, the SI traceability of spectroradiometric measurements needs to be ensured. For decades, the calibration of spectroradiometric measurement instruments has been realised using incandescent lamp based transfer standards. However, their availability is diminishing due to a production phaseout of incandescent lighting products. This project aims to provide adequate and affordable replacement transfer standard light sources and alternative procedures for the detector based transfer of the spectral irradiance unit in the ultraviolet visible near infrared (UVVISNIR) spectral range. It also aims to establish an integrated European metrology infrastructure around this key radiometric unit.
