FC24M Series: These 1.1-inch, 24-megapixel lenses are compact and high-resolution. Their floating mechanism system corrects aberrations, and the wide-band multi-coating minimizes ghosting and flare.
HC Series: The 1-inch megapixel HC lenses offer excellent corner brightness and low distortion, encompassing various focal lengths.
HC-V Series: Designed for high-vibration and shock environments, these ruggedized 1-inch megapixel lenses maintain optical performance using a unique mechanical design. The two-way reversible nut secures focus adjustment and eliminates screw loss issues.
JC10M Series: These 2/3-inch, 10-megapixel lenses are optimized for high-end inspection, boasting 200 lp/mm center resolution and low distortion. Aspherical lenses and a compact design improve system integration.
JC5M2, JC5MC Series: The JC5M2 and JC5MC Series are both 2/3-inch, 5-megapixel lenses with differing compact designs and features. The JC5MC lenses are particularly noteworthy for their small size and weight.
JCM-V, JCM-WP Series: These ruggedized 2/3-inch megapixel lenses are designed for high-vibration environments. The JCM-WP adds water and dust resistance, improving durability for demanding applications.
JC1MS Series: The JC1MS Series represents a wide range of 2/3-inch megapixel lenses, known for their excellent corner brightness and low distortion.
JC Series: The JC series represents a line of standard 2/3-inch lenses known for their cost-effectiveness and durability.
NCM/JCM Series: These wide-megapixel lenses provide a large angle of view with superior optical design to reduce distortion.
HC-VIS-SW Series: The 1-inch HC-VIS-SW series are 12-megapixel lenses with IR correction for use in visible and near-infrared (SWIR) ranges, and virtually no focus shift.
JC5M-IR Series: These 2/3-inch, 5-megapixel lenses feature IR-corrected design and a fast F-stop.
HC-SW Series: The HC-SW lenses utilize Kowa's special coating to maximize transmission for Near Infrared (NIR) and Short Wavelength Infrared (SWIR) applications.
Additional features: Many lens series feature low distortion, floating mechanisms for aberration correction, and wide-band multi-coating for improved transmission.
Accessories: Kowa also offers accessories such as close-up rings, filter holders, and mount adapters, further enhancing the versatility and customization options for their lenses. Detailed specifications, including image size, field of view, and distortion, are provided for each lens model.
