Varifocal DC Auto Iris Lens

This is the Kowa LMVZ41A varifocal auto iris direct control (dc) type lens. The LMVZ41A has a focal length of 4-10mm. The LMVA41A has an 1.8-360 iris range. The 3-Cam Design can minimize a need for grease for the operation of the focusing system and allows for improving an environmental adaptability against temperature change. The 3-Cam design can reduce the internal reflection and obtain sharper images because of the light shield processing. This feature is not available with the conventional Pole system design.

→ 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 3-Cam Design, the customer can expect higher optical performance and a longer service life
