Why Optivex?

Ultraviolet radiation surrounds us all of the time. But far from being harmless, persistent UV exposure can degrade and damage priceless paintings, valuable fabrics, and rare historical documents. Adding EMF's Optivex™ dichroic filters to lighting fixtures blocks 99% of harmful UV radiation while transmitting high quality visible light with virtually no distortion.

Optivex™ has been the product of choice for over 25 years and its name is synonymous with absolute protection.
