CANTY fiber optic lighting systems have been designed to provide efficient, high LED light in a cost effective package. CANTY uses only high quality, flexible fiber optic light pipes to guide the light from our light source through a sight glass or process connection. The light is elliptically focused into the fiber optic light pipe and guided through the sight glass minimizing losses while maximizing your tank or vessel lighting!All CANTY sight glasses feature the Fuseview™ window. Our unique fused glass windows far exceed all conventional tempered glass windows in safety and performance. By fusing glass to metal, a high pressure, high safety, hermetic seal is formed. The fused glass Technology ensures safety with every Fuseview™.
