The 3-Cam design is incorporated into Kowa’s LMVZ256A 1/3" 2.5 to 6mm Varifocal Auto Iris Lens (DC). This innovative system has solved the problem of de-centering which sometimes occurs in the conventional pole system. Not only is the movement of the lens impaired by de-centering, but the optical performance suffers too. The 3-Cam design also reduces internal reflection. As a result, the image obtained by this design is much sharper than that of the conventional pole system. With the 3-Cam design, the customer can expect high optical performance and a long service life.
