In high-radiation environments, standard lenses can suffer from brown discoloration of the glass, which obstructs light and impairs imaging quality. Kowa’s LM15FC-R anti-radiation lens is specifically designed to withstand such conditions, offering unparalleled optical clarity in environments where radiation exposure is a constant factor. With a focal length of 15mm and radiation-resistant glass, the LM15FC-R ensures consistent performance over extended periods in radiation-prone areas such as research labs, radiation facilities, and even space applications. The lens’s robust mechanical design includes water and dust resistance, making it suitable for tough industrial environments.

Key features include a 1.1” 24 MP resolution for sharp imaging, a wide iris range (F2.8–F10), and a double-nut focus adjustment system for precise control. The LM15FC-R is built to order, allowing you to tailor the lens to your specific needs.
Why Choose the LM15FC-R?
