For applications requiring long range surveillance, the Kowa LMVZ990 IR 1/2" 9 to 90mm Day & Night Lens (IR) has one of the largest focal ranges of Day & Night Varifocal lens in the industry. This product was specifically designed for applications such as highway surveillance to read vehicle license plates traveling at a high rate of speed or for other long range monitoring needs.
Common in lenses in the broadcast industry, the 3-Cam design is also incorporated in Kowa’s varifocal and zoom lens. 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 higher optical performance and a longer service life.
