For more than 55 years, Shanghai Optics has been creating and producing high-quality infrared (IR) lenses, such as spherical, aspheric, zoom, beam expander, fixed focal length, and objective lenses.

The company provides clients with the best-value options in high-performance infrared lenses covering a significant infrared spectrum range. Numerous applications for infrared lenses include temperature detectors, thermal imaging systems, security cameras, infrared magnifying and zoom systems, and infrared thermal displays.

Shanghai Optics designs high-performance IR lenses to ensure a high manufacturing yield. Utilizing advanced in-house manufacturing and testing equipment, the company produces IR lenses cost-effectively and highly efficiently.

To guarantee system-level success, rigorously monitor the quality of each optical component during production. The company employs the ISO 9001 certified procedure and highly dependable measuring systems for component quality inspection at every stage of the manufacturing process to meet and exceed high requirements.

Shanghai Optics conducts comprehensive in-house inspections on component and assembly characteristics according to customer specifications. This includes MTF, the field of vision, transmission, reflectivity, effective focal length (EFL), distortion, filed curvature, astigmatism, etc.

Shanghai Optics guarantees that every IR lens performs to the satisfaction of clients. To evaluate the Modulation Transfer Function (MTF) and optical parameters over a wide spectra range, including UV, Visible, NIR, SWIR, MWIR, and LWIR spectra, they employ in-house ImageMaster^® Universal – MTF Testing in the Spectral Range UV-VIS-NIR-SWIR-MWIR-LWIR.

Shanghai Optics leverages its expertise to assist customers in designing and manufacturing high-performance IR lenses and components. The capabilities span from simple fixed-focus objective lenses to intricate opto-electro-mechanical modules, ensuring they meet diverse requirements with precision and excellence.

To satisfy clients' unique requirements, the company provides bespoke IR lens solutions, such as a specialized dual-band lens for visible and SWIR spectra. The engineers excel in material selection for color correction across two spectral bands simultaneously and Design for Manufacturing.

Shanghai Optics specializes in producing custom dual-band lenses with transmission rates exceeding 80%, ensuring high image quality in both the visible and short-wave infrared (SWIR) ranges (700 – 1900vnm).

Thanks to IR knowledge and adaptability, customers with IR lens application demands can use Shanghai Optics' IR design service to realize their innovative concepts and unique requirements, ranging from basic fixed-focus objective lenses to intricate opto-electro-mechanical modules.
