CNGEIR: Mastery in Infrared Aspheric Optics
Headquartered in the Nanjing Li Shui Economic Development Zone, CNGEIR operates a 120,000-square-meter facility with over 300 employees and a global network of sales teams in Europe, the U.S., Japan, and South Korea. The company’s core expertise lies in germanium-based infrared aspheric lenses, critical for thermal imaging, night vision systems, and military targeting applications.
CNGEIR’s end-to-end production chain includes:
Optical Processing: Precision diamond turning and magnetorheological finishing (MRF) for infrared aspheric lenses with surface accuracy <0.1 μm.
Mechanical Fabrication: CNC-machined aluminum and titanium housings for athermalized lens assemblies.
Testing & Integration: Active alignment of infrared aspheric lenses with cooled thermal detectors and photoelectric turntables.
The company’s custom asoheric lens are engineered for the 3–12 μm wavelength range, using materials like germanium (Ge) and chalcogenide glasses (GASIR®). These lenses enable compact designs for UAV-mounted thermal cameras and automotive LiDAR systems, reducing spherical aberration by up to 90% compared to spherical equivalents. With 60 years of infrared expertise, CNGEIR also produces custom aspheric lenses for mid-wave infrared (MWIR) applications, leveraging silicon’s high thermal conductivity for high-power laser systems.
Shanghai Optics: Precision for Demanding Applications
Shanghai Optics is a leading aspheric lens manufacturer, offering custom aspheric lenses in materials ranging from N-BK7 to zinc sulfide (ZnS). Their proprietary molding process achieves form tolerances of λ/2 PV, ideal for high-resolution SWIR imaging. The company’s infrared aspheric lenses feature anti-reflective coatings optimized for 1.5–5 μm wavelengths, widely used in gas detection and semiconductor inspection.
ChineseLens: High-Volume Production Expertise
ChineseLens specializes in mass-producing silicon aspheric lenses for consumer electronics, including smartphone LiDAR modules. Their reactive ion etching (RIE) technique reduces surface roughness to <10 nm, minimizing scatter losses. The company also provides aspherical lens manufacturer services for industrial robotics, offering lenses with 0.5–50 mm diameters and NA up to 0.7.
Diverse Optics: Polymer Aspheric Innovation
Diverse Optics leverages injection molding to produce lightweight custom aspheric lenses in cyclic olefin copolymer (COC) and PMMA. Their infrared aspheric lenses for medical devices (e.g., endoscopes) incorporate diffractive optical elements (DOEs) to correct chromatic aberrations in the 700–1600 nm range.
Ecoptik: Hybrid Material Solutions
Ecoptik designs hybrid silicon aspheric lenses bonded with germanium for dual-band (visible + LWIR) surveillance systems. Their proprietary bonding technique eliminates interfacial reflections, achieving >95% transmission. The company also offers aspheric lens manufacturers ultra-broadband AR coatings (0.4–12 μm) for multispectral drones.
