LWIR - Athermal

SOT-LW-A-90F1

The 90mm F1.0 infrared athermal lens is engineered for high-performance thermal imaging and security applications. Designed to maintain consistent optical performance across varying temperatures, it ensures sharp, detailed images even in challenging environments.

  • Long-range imaging capability ideal for surveillance and monitoring
  • Passive athermalization delivers stable focus from -40°C to +80°C
  • High-durability anti-reflection coatings optimized for LWIR or MWIR bands
  • Compatible with a variety of detector formats and pixel pitches
  • Provides superior image clarity from close range out to infinity
  • Cost-effective solution for high-resolution thermal imaging systems
