High Precision Optical Achromatic Doublet Lens with AR Coating for Microscopes
1. Material Composition:
Achromatic Doublet Design: Precisely bonded elements using crown glass (e.g., N-BK7) and flint glass (e.g., F2) to eliminate chromatic aberration.
Multi-Layer AR Coating: Ion-beam sputtered anti-reflective coatings optimized for visible spectrum (400-700nm) with >99.5% peak transmission.
2. Key Properties:
Chromatic Aberration Correction: Reduces axial and lateral color fringing to ensure true-color imaging.
High Wavefront Accuracy: λ/4 surface precision and <30 nm RMS wavefront error for diffraction-limited performance.
Thermal Stability: Near-zero thermal shift (-30°C to 80°C operational range) due to matched CTE glass pairing.
Scratch/Dig Standard: 10-5 surface quality with laser-grade polishing for minimal light scatter.
3. Core Functions:
Color Fidelity Enhancement: Corrects multi-wavelength focus shifts for accurate sample reproduction.
Contrast Optimization: AR coatings minimize reflections to boost image contrast in high-magnification systems.
Long Working Distance: Enables focus stability in complex optical paths (e.g., objective lenses, tube lenses).
4. Applications:
Research Microscopy: Fluorescence, confocal, and phase-contrast microscopy requiring color accuracy.
Medical Diagnostics: Pathology lab microscopes and digital slide scanning systems.
Industrial Inspection: Semiconductor metrology, PCB analysis, and material science imaging.
Life Sciences: Cell culture monitoring and histology sample examination.
