LWIR - Dual Field-of-view (FOV)

SOT-LW-D-50100

The 50–100mm F1.1 dual field-of-view (FOV) infrared lens allows rapid switching between wide and narrow fields of view without moving the lens, making it ideal for dynamic surveillance applications. Its versatile design enables both general area monitoring and precise target identification.

  • Dual FOV for seamless switching between wide-area and focused imaging
  • High-performance AR coatings optimized for LWIR/MWIR bands
  • Ideal for surveillance, security, and monitoring applications
  • Compatible with multiple detector formats and pixel pitches
  • Maintains sharp, detailed images across both FOV modes
  • Cost-effective solution for flexible infrared imaging systems
