氘放电灯与氟化镁窗口密封到信封通过纯玻璃吹制技术已经开发出在NPL作为辐射传输标准之间的115和370 nm。它示出了如何在校准阶段提供的光谱辐射度系统的带宽是已知的，在165 nm以下的氘的复杂的分子发射光谱的问题被克服。总功耗约15 W，结构紧凑，易于使用，高辐射率和老化率小于0.05%h-1的一些优点进行了讨论。
Deuterium discharge lamps with magnesium fluoride windows sealed to envelopes by means of pure glass-blowing techniques have been developed at NPL as radiance transfer standards between 115 and 370 nm. It is shown how the problems of the complex molecular emission spectrum of deuterium below 165 nm are overcome at the calibration stage provided the bandwidth of the spectroradiometric system to be calibrated is known. Total power dissipation of about 15 W, compact construction, ease of use, high radiance and aging rates less than 0.05% h-1 are some of the advantages discussed.
