Kowa LM25JC10M 2/3″ 25mm F1.8 Manual Iris C-Mount Lens, 10-Megapixel
Security and Factory Automation Lenses
Kowa : LM25JC10M
Description
The Kowa LM25JC10M 2/3″ 10 megapixel lens provides 200lp/mm resolution and low distortion in order to maximize performance for high-end applications. Incorporating Kowa’s broadband coating and floating mechanism design, the LM25JC10M lens greatly reduces chromatic aberration at any distance and maintain a high transmission from visible to NIR.
Floating Mechanism Design
Kowa’s floating mechanism design virtually eliminates optical abberations from close distance to infinity
Low Distortion
High precision aspherical lens greatly reduces distortion and produces a high definition picture
200lp/mm Resolution and Low Distortion
200lp/mm resolution and low distortion will maximize performance for high-end applications
High Transmission from visible to NIR
JC10M Series incorporates wide-band coating and a floating mechanism design to maintain a high transmission from visible to NIR
Easy Installation
Short minimum object distance and compact design using aspherical lenses (5 models/F-5 ~ 25mm) will allow for easy installation in compact machine vision systems
