Multi-Layer AR Coating Optical Plano Lens for Scientific and Research Applications

Multi-Layer AR Coating Optical Plano Lens for Scientific and Research Applications 

1. Material Composition:

• Optical Glass Substrate: High-grade materials like Schott N-BK7, fused silica, or specialty crystals ensuring low thermal expansion and homogeneity.

• Multi-Layer AR Coating: Precision-deposited anti-reflective layers optimized for specific wavelengths (e.g., UV, visible, or IR spectra).

2. Key Properties:

• Ultra-Low Reflectivity: Achieves >99.5% light transmission per surface with near-zero reflection losses.

• Wavelength Specificity: Customizable coatings for target ranges (e.g., 400-700nm, 1064nm laser lines, or broadband IR).

• Environmental Durability: Resists humidity, abrasion, and thermal cycling (-40°C to 300°C operational range).

• Surface Precision: λ/10 flatness and 10-5 scratch-dig standards for wavefront integrity.

3. Core Functions:

• Light Transmission Maximization: Eliminates Fresnel reflections to enhance signal-to-noise ratios in optical systems.

• Beam Steering & Splitting: Serves as a neutral substrate for laser path control or beam combiners.

• Optical Interface Protection: Shields sensitive instruments from back-reflections and stray light.

4. Applications:

• Research Microscopy: Confocal, fluorescence, and super-resolution systems requiring minimal glare.

• Laser Systems: Cavity mirrors, harmonic separators, and interferometry components.

• Spectroscopy: Windows for spectrophotometers, monochromators, and FTIR instruments.

• Aerospace & Defense: Targeting systems, LIDAR, and high-energy laser applications.
