UV & IR Blocking Filters
UV Blocking Filters
UQG UV Blocking filters block harmful UV radiation allowing excellent transmission of the visible, protecting UV sensitive materials and components. The filters will reduce photochemical degradation without damage to the components when the light source is intensified.

IR Cut Of Filters
UQG IR cut off filters block the IR transmission while passing the visible. They produce true colour appearance and avoiding colour deviation, they keep the primary colours display natural and vivid reality.
