  • Excellent for Long Range Detection
  • LWIR Lens Assemblies are also available


MWIR (Midwave Infrared) Thermal Imaging Camera Lenses are lenses oriented for operation in the 3-5 micro wavelength spectrum. Since the thermal contrast is stronger in the MWIR region than in the LWIR region, and the MWIR radiation is less susceptible to thermal diffraction, the lenses, combined with sensitive cooled FPA detectors within an MWIR thermal camera, are more capable of generating images with high resolution, contributing to revolutionized overall image qualities. MWIR thermal camera lenses are also considered more suitable candidates for long-range detection than LWIR lenses. Shalom EO’s MWIR lenses feature optimized Modulation Transfer Function (MTF) and exceptional Detection, Recognition, Identification (DRI) functionalities. The lenses, with a broad portfolio of varied specifications, support detection under poor atmospheric/illumination conditions (e.g. in fog/ complete darkness), and even allow objects that are invisible to be captured (e.g gas leakage). Shalom EO’s MWIR lenses are excellent alternatives for thermal imaging in various domains, including industrial, academic, surveillance, and homeland security applications.

Hangzhou Shalom EO offers off-the-shelf and custom Lenses for Thermal Imaging Cameras. For MWIR Lens Modules, a wide assortment of lenses is available, including MWIR Single FOV Lenses with a designated focal length and FOV each, MWIR Dual FOV Lenses with two selectable focal lengths, and MWIR Continuous Zoom Lens Assemblies which enable continuous shifting of focal lengths, permitting flexible observation over a wide range of distances and real-time detection. In recent months, Shalom EO has developed a new series of Ultra-Lightweight >1000mm Focal Length MWIR Lens Modules with motorized continuous zoom and focus mechanism, featuring a maximum focal length of 1100mm at an f-number of 5.5, and reduced weight of 4.2kg. We utilize various materials with high MWIR transmission including Germanium, ZnSe, Chalcogenides, Zinc Sulfide, GaAs, and Silicon to manufacture the lens substrate, and anti-flection (AR) coatings, Diamond-Like Carbon (DLC) coating could be furnished on the front lens exposing to air according to your requirements. 

Over the years, Shalom EO has built a solid reputation as a manufacturer and global supplier of infrared thermal imaging len,ses. Our lens production line incorporates cutting-edge processes such as CNC fabrication and single-point diamond turning (SPDT) polishing, under stringent QC procedures. The sealings of lens groups are IP67 rated, dust-tight, and waterproof.  Built-in manual and motorized focus mechanisms are integrated into focal length-variable lens modules, and compact mechanical designs for lightweight concerns can be designed upon request. In addition, Optical Passive Athermalized lens modules to compensate for temperature fluctuations are also accessible both in our stock list and as custom products.
