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

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.
