ABSTRACT:
The solar blind ultraviolet filter includes in an intimate cascade relationship an ultraviolet grade quartz cell containing chlorine gas receiving light energy on an input face thereof, a first Jena UG5 glass cell containing potassium iodide doped with thallium, a second Jena UG5 glass cell containing a 2, 3-dihydro-5, 7-dimethyl-1H-1, 4-diazepine perchlorate and glycerol solution and a Jena UG5 glass and ultraviolet grade quartz cell containing nickel sulfate hexahydrate as the output element of the filter. A black anodized aluminum shell encloses the peripheral surface of all of the above cells. An extremely high viscosity interface coupling medium, such as dimethyl polysiloxane, is disposed at all interface surfaces of the various materials employed in the filter to minimize reflection losses at these interface surfaces.
