12mm 4/3" Megapixel Lens

The Kowa LM12XC 4/3" megapixel lens provides a large image format of Φ23mm(C-mount). These high precision aspherical lenses greatly reduce distortion and produces a high definition picture. LM12XC lenses maintain megapixel resolution thoughout the entire image even if the iris is fully open. In addition, Kowa's wide-band multi-coating effectively reduces glare and refraction.
