Datasheet: Calibrated Forward Spectral Flux Standards

Labsphere's Lamp standards of forward spectral flux are selected for their stability and reproducibility. Each standard has been carefully screened, seasoned, and calibrated at our manufacturing facility under the guidelines recommended by the IESNA (Illuminating Engineering Society).

Labsphere's lamp standards of total forward spectral flux provide an exceptional artifact for calibrating integrating sphere spectrometers for total spectral radiant flux responsivity from 350 to 1050 nm. All of Labsphere's standard lamps are first seasoned for 1% of their rated life and then screened for stability and repeatable performance before they are selected for calibration. The selected lamps are then calibrated directly to the NIST lumen, for a calibration result you can rely on.
