Long Wave Infrared (LWIR) thermal imaging camera lenses are integrated lens assemblies designed to match with uncooled infrared FPA detectors/sensors, operating at 8-12 micron wavelength region. Compared to MWIR thermal lenses, LWIR lenses have the distinctive feature of insuceptiblities to the disturbations from additional light/heat sources, and are more affordable than the former. A set of LWIR lens modules, for the most part, is constituted from multiple (>2) single IR lenses of different surface profiles (e.g. diffractive lens, aspheric lens) or various LWIR-transmitting materials (e.g Ge, ZnSe, Chalcogenides, etc.) with complementing optical properties to compensate the spherical and chromatic aberrations and optimize for the image quality. With excellent detection, recognition, and identification (DRI) capabilities, the lens assemblies meet the specific requirements for a wide range of industrial, medical, commercial, defense, and homeland security applications.

Hangzhou Shalom EO offers off-the-shelf thermal camera lenses and custom lens modules, hundreds of stocked LWIR lenses, with individual specifications listed are prepared for online purchasing. Shalom EO utilizes a wide assortment of materials including Germanium, Zinc Selenide, Chalcogenides, ZnS, and Gallium Arsenide(GaAs), etc. as LWIR lens substrates, furnished with anti-reflection (AR) coatings or diamond-like carbon(DLC) coatings on the lens front. The LWIR thermal lenses are categorized into six classifications: Athermalized Lenses exhibit high resistance to temperature fluctuations thus shrinking the possibilities of defocus at unstable temperatures, Super Wide Angle and Fisheye Lenses provide broad fields of view. Single FOV Lenses are endowed with a certain designated focal length each, generating a particular FOV, while Dual FOV Lenses have two switchable focal lengths each and hence a double FOV. The Zoom Lenses have continuous variable focal lengths, allowing flexible observation over a wide range of distances and real-time detection. And Microscope IR Lenses are also available.

Shalom EO has established its trustful image as a manufacturer and a worldwide supplier of Infrared thermal imaging lenses over years of dedication. Our lens production line is of cutting-edge techniques under rigorous inspection, including CNC fabrication and single-point diamond turning (SPDT) polishing. The sealings of lens groups are IP67 rated, dust-tight, and waterproof. For focal length-variable lens modules, built-in manual and motorized focus mechanisms are incorporated, where compact mechanical architectures for lightweight concerns s could be customized upon request. Other specifications and structures such as pinhole lenses for temperature monitoring in furnaces could all be arranged.
