Botany Facility: Breadboarding results of the illumination system
Abstract
Experiments were undertaken to establish a suitable configuration for the EURECA Botany Facility illumination system. The basic requirements for the illumination system are presented. The relationship between photometric and radiometric measurements is discussed. Experimental data aiming at the establishment of a lamp running-in period are discussed. The lamp-to-lamp light output variation was assessed. The results of experiments aiming at the establishment of a suitable cuvette reflector design are treated, including an assessment of the fluorescent lamp reflector design and the back and sidewall reflectors for the cuvettes. The preferred design was analyzed with respect to absolute illuminance and uniformity at the base of the cuvettes. The temporal variation of the cuvette-cuvette light level was assessed.
