For applications requiring long range surveillance, the new KOWA Day & Night
series LMVZ990A IR has the largest focal range 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 lenses.
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 LMVZ990AIR 3-Cam Design, the customer can expect higher optical performance and a longer service life.
