2/3″ Anti-Shock & Vibration JCM-V Series

Kowa’s new JCM-V series is made for use in high vibration and high shock environments.  With a design based on Kowa’s standard 2/3″ JCM lenses, this new ruggedized megapixel lens series is ideal for applications that require increased durability and high optical performance.


• For megapixel applications requiring a sensor size of 2/3″ (Φ11mm) or smaller.
• Unique mechanical design to guard against strong vibration & shock.
• Two way reversible nut is utilized to tightly lock the focus adjustment ring in place.
• All internal glass elements are glued to the inside housing to improve durability.
• Ability to choose from four interchangeable iris plates. This provides the flexibility of having an adjustable F-stop while maintaining the advantage of a fixed iris with no moving parts.
