Kowa LM15FC-R | 1.1" 15mm Fixed Focal Length IR-Corrected Lens, 24MP, C-Mount, 2.5µm Pixel, Radiation-Resistant Glass, Visible to NIR (400–1000nm)
The Kowa LM15FC-R is a precision-engineered 1.1" C-mount industrial lens designed for high-resolution imaging systems with sensor compatibility up to 24 megapixels and a 2.5µm pixel pitch. Featuring a fixed 15mm focal length and IR-corrected optics, this lens performs optimally across the visible to near-infrared spectrum (400–1000nm), supporting demanding applications such as machine vision, scientific research, and industrial inspection. With optical resolution reaching 200 line pairs per millimeter at the center and 125 lp/mm at the edges, it ensures sharp and distortion-minimized imagery (-2.12% TV distortion) over a wide field of view.
Built with radiation-resistant glass, the LM15FC-R maintains optical clarity and prevents discoloration even in radiation-prone environments, enhancing durability and reliability. Manual focus control spans from 0.1 meters to infinity, allowing precise adjustments for varying working distances. The lens supports stable operation within a temperature range of -10°C to +50°C, making it suitable for a variety of industrial settings. Compact and lightweight (70g), the lens’s patented design provides consistent performance in critical imaging tasks requiring accuracy and environmental resilience.
