MWIR Fixed-Focus Imaging Lens

Mid-Wave Fixed-Focus IR Lens (3-5μm) - High-Performance Thermal Imaging Solution  Our Mid-Wave Infrared (MWIR) Fixed-Focus Lens delivers exceptional clarity and sensitivity for 3-5μm thermal imaging applications. Engineered with precision germanium optics and anti-reflective (AR) coating, this lens ensures >90% transmission at 4μm, maximizing detection accuracy. Featuring a fast f/2.0 aperture, it achieves <20mK NETD thermal sensitivity, ideal for detecting subtle temperature differences in gas leak detection, industrial monitoring, and defense systems. The rugged design operates in -40°C to +80°C environments, with optional DLC coating for enhanced durability. Standard C-mount interface ensures compatibility with FLIR, SCIENCAM, and other cooled MWIR detectors (640×512/1280×1024). Available in 50mm, 85mm, and 120mm focal lengths for flexible deployment.  Key Features: Spectral Range: 3-5μm (MWIR) Focal Length Options: 50mm/85mm/120mm Aperture: f/2.0 (f/1.8 optional) Thermal Sens…
