MidOpt Protective filters

AC and LP series

The AC and LP series are designed to shield the lens and lighting from dirt, dust, liquids, impact and harsh environments without sacrificing image quality. They are available in glass and acrylic with a high-efficiency, anti-reflection coating to maximise transmission to 98% or more. These filters are useful for imaging in ultraviolet, visible and near-infrared spectra. The protective filters are an economical way of protecting expensive lenses.

The AC series is an acrylic longpass protection filter while the LP series is made of glass.
