150 mm 200 mm 300 mm Diameter AR Coating Optical Lens for Imaging and Medical Device

1. Material & Construction

• Substrate Materials: Commonly optical glasses (N-BK7, Fused Silica), crystals (CaF2), or specialized polymers. Material selection is critical for transmission and durability in medical environments.

• Diameter Range: Specifically engineered in large aperture sizes: 150mm, 200mm, and 300mm.

• Coating: Features Anti-Reflective (AR) Coating, optimized for high transmission at specific wavelengths (e.g., visible, NIR, or specific laser lines).

2. Key Properties

• Large Clear Aperture: Enables collection and transmission of large beams or wide fields of view with minimal vignetting.

• High Transmission & Low Loss: AR coating significantly reduces Fresnel reflections (often to <0.5% per surface), maximizing light throughput and image brightness.

• Wavefront Precision: Manufactured to high surface accuracy (e.g., λ/2 or λ/4) to minimize optical distortion and aberrations over the large area.

• Durability & Cleanability: Designed to meet rigorous standards for cleaning, sterilization (where applicable), and long-term stability in clinical or industrial settings.

• Precision Mounting: Compatible with robust mechanical housings or lens cells for secure integration.

3. Primary Functions

• Light Collection & Transmission: Efficiently gathers and transmits large amounts of light or large-diameter beams.

• Image Transfer: Serves as a critical window or objective lens in large-format imaging systems.

• Beam Conditioning: Functions as a collimating, focusing, or relay lens for expansive optical paths.

4. Common Applications

• Medical Imaging Devices: Key optics in large-format X-ray detectors, digital radiography flats, surgical microscope objectives, and ophthalmic diagnostic systems.

• High-Resolution Industrial Imaging: For large-area inspection systems, aerial mapping cameras, and photolithography.

• Scientific & Research Instruments: Used in astronomical telescopes, spectroscopy setups, and large-beam laser laboratories.

• Defense & Aerospace: As windows, objectives, or relay lenses in surveillance, reconnaissance, and targeting systems.
