Kowa’s new JCM-V Series is designed for use in high vibration and 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.
1. The JCM-V series uses interchangeable iris plates instead
of mechanical iris diaphragms with moving blades. You
can choose from four iris plates to adjust the F-stop.
2. Unscrew the bottom ring of the outside body to adjust the focus to optimal position.
3. Screw the red two way reversible nut on the center body towards the bottom ring to lock in the focus.

◇: Suitable
JCM-V series is ideal for applications that require increased durability and high optical performance.
There are risks when using a general off-the-shelf lens whilst under vibration and shock conditions.
In the iris mechanism of a general off-the-shelf lens, dust can come from out of the iris parts by repeating iris sliding.
The dust on a lens element can cause a false detection.
External factors such as vibration and shock can cause an optical-axis-shifting.
As a result, the resolution may decrease and the expected image may not appear.
General off-the-shelf lenses use thumb screws for iris and focus adjustment.
External factors such as vibration and shock can cause thumb screws to fall off,
which decreases in efficiency and safety in a production line.
Adjustment of F number can be done by just inserting a right interchangeable iris plate.
The plate minimizes a risk of dust falls rom iris parts to lens elements and keep clean condition.
Minimization of deviation in the optical axis whilst under vibration and shock conditions
by gluing the lens elements and mechanical parts.
Elimination of thumb screws and use of a double nut system to tightly fix focus.
Low risk of loosening (lost focus) and falling parts. Lens design and body remains compact.
*To improve ruggedized performance, we recommend applying adhesive to each screw to prevent loosening.
Images may differ from the actual product.
