Overview of infrared IR lenses

We can provide a large number of customized infrared IR lenses and components for focusing, collimating, and collecting light in the Near Infrared (NIR), Short Wave Infrared (SWIR), Medium Wave Infrared (MWIR), and Long Wave Infrared (LWIR) spectra. By adhering to high manufacturing and ISO standards, we produce high-performance infrared IR lenses that meet customers’ needs for industrial, medical devices, life sciences, and defense applications.

We have extensive experience in manufacturing high-quality infrared IR lenses. Our infrared IR lenses have been used in surveillance cameras, infrared amplification systems, infrared zoom systems, infrared thermal displays, thermal imaging systems, temperature detectors, and many other fields.

With powerful internal manufacturing and testing equipment, we produce infrared IR lenses in a cost-effective and fast delivery manner. We strictly control the quality of each optical component in production to ensure system level success. In order to meet and maintain our high quality standards, we use ISO 9001:2008 certified processes and highly reliable measurement systems to conduct component quality inspections at every step of the manufacturing process.

We perform precise testing of internal components and assembly characteristics according to customer specifications, including MTF, field of view, transmittance, reflectivity, focal length (EFL), distortion, curvature, astigmatism, etc. We ensure that the performance of each product’s infrared IR lens meets customer needs.
