The quartz plate is generally place between the lamp and the substrate. The plate does not absorb UV rays but helps in reradiating the rays at a temperature lower than that of the lamp.
The main use of a quartz plate in the lamp is to prevent the accumulation of debris, dirt and contaminants from building in the filter.
