Key Characteristics:

1. Material: ZnSe is a compound semiconductor material known for its high transparency in the mid-infrared region. It has excellent optical properties and is often used in thermal imaging cameras, laser systems, and other infrared optical devices.
2. Aspheric Design: Unlike traditional spherical lenses that suffer from spherical aberration, aspheric lenses have surfaces that deviate from a simple spherical shape. This design helps to reduce or eliminate spherical aberration, thereby improving the focus and image quality across the entire field of view.
3. Applications: ZnSe aspheric lenses are widely used in various applications such as:
- Mid-infrared spectroscopy
- Thermal imaging systems
- CO2 laser systems
- Medical imaging devices
- Environmental monitoring instruments
4. Fabrication: These lenses are typically fabricated using advanced manufacturing techniques such as precision molding or diamond turning. The process ensures that the surface accuracy is maintained to very tight tolerances, ensuring optimal optical performance.
5. Surface Coating: To further enhance their performance, ZnSe aspheric lenses may be coated with anti-reflective coatings. These coatings help to minimize reflections and increase transmission efficiency, which is crucial for maintaining high signal-to-noise ratios in sensitive optical systems.
