Design optical systems that meet requirements for parameters such as field of view (FOV), resolution, and focal length based on application needs. For example, infrared thermal imaging lenses for security monitoring may require a larger FOV to cover broader areas, while lenses for industrial inspection may prioritize high resolution and telephoto performance to observe distant targets clearly.
Aberration Correction
Optimize lens shape, material, and combination to correct various aberrations (e.g., spherical aberration, coma, chromatic aberration), ensuring high-quality infrared images with sharp, distortion-free object edges.
Aspherical and Diffractive Surface Applications
Master the design and manufacturing techniques for aspherical and diffractive surfaces to reduce lens component count, lower costs, improve imaging quality, and achieve miniaturization. For instance, lenses composed of high-precision aspherical and diffractive surfaces can be used in drone systems for aerial payloads, offering long optical paths and large zoom ranges.
Material Selection and Application Capabilities
Infrared Optical Material Properties
Deeply understand the properties of various infrared optical materials (e.g., refractive index, dispersion, thermal expansion coefficient, transmittance), and select appropriate materials based on the lens’ operating wavelength range and temperature environment. For example, chalcogenide glass is widely used in infrared thermal imaging lenses due to its high transmittance in the infrared band and good thermal stability.
Athermalization Material Applications
Choose materials with suitable thermal properties for athermalized designs to ensure stable imaging performance across different temperatures. For example, combining materials with different thermal expansion coefficients or using special optical materials and structural designs can maintain optimal lens performance in operating temperature ranges of -35°C to +65°C or even wider.
Processing and Manufacturing Capabilities
Precision Machining Techniques
Possess high-precision machining processes (e.g., diamond turning, precision molding) to fabricate optical components (e.g., lenses, lens barrels) with extremely tight dimensional tolerances and surface quality requirements. For instance, precision molding enables mass production while ensuring strict tolerances and stable product quality.
Coating Technologies
Master coating processes for infrared bands (e.g., anti-reflective coatings, protective films) to enhance lens transmittance and durability. For example, high-efficiency anti-reflective coatings can be applied across the full-wave infrared band (8–14μm), with optional DLC (diamond-like carbon) coatings as additional protection to improve scratch and corrosion resistance.
Assembly, Alignment, and Testing
Utilize professional assembly techniques and equipment to precisely assemble optical components, followed by rigorous testing and calibration to ensure lens optical performance meets design specifications.
