1 Scope

This procedure applies to the first of the spectral radiance standard lamps (referred to as standard lamps) in the range of 250~2500nm. Sub-tests, subsequent tests and in-use tests. Spectral radiance standard lamp calibration and prototype test Performance requirements can be implemented with reference to this procedure.

2 Overview

Spectral radiance standard lamp is a standard gauge for maintaining and transmitting spectrally dense metrics of radiance With. It can also be used to calibrate the spectral radiance distribution and spectral spokes of various radiation sources in the 250~2500nm spectral range. Calibration of the radiometer, etc. The unit of spectral intensity of radiance is μW·cm -2 · nm -1 · sr -1 . Spectral radiance standard lamp is a special tungsten lamp with two models. BDW with quartz window and BW type without window. BW standard lamp for visible and near infrared radiation, BDW standard lamp for violet External, visible and near-infrared radiation bands. The electrical parameters of BW and BDW standard lamps are shown in Table 1. See Figure 1 and Figure 2.
