Low-Dispersion Focusing Convex Achromatic Lens for Collimators
1. Material Composition:
Low-Dispersion Glass: Combines specialized glasses (e.g., ED glass, FK61, or N-BK7/F2 achromatic pair) to minimize chromatic aberration.
Precision Optical Substrate: High homogeneity glass with λ/4 surface accuracy and laser-grade polishing.
2. Key Properties:
Chromatic Aberration Correction: Eliminates multi-wavelength focal shift for precise beam alignment.
High Numerical Aperture (NA): Enables efficient light collection and tight focusing capabilities.
Thermal Stability: Low thermal expansion coefficient maintains performance in varying temperatures.
AR Coating Options: Broadband or wavelength-specific anti-reflective coatings (>99.2% transmission).
3. Core Functions:
Beam Collimation: Converts divergent light into a parallel beam with minimal spherical/chromatic errors.
Focusing Optics: Precisely concentrates polychromatic light to a single point for imaging or laser systems.
Wavefront Correction: Compensates for aberrations in complex optical assemblies.
4. Applications:
Laser Collimators: Fiber-coupled laser systems, Lidar, and interferometry devices.
Microscopy: Confocal and fluorescence microscope objectives requiring achromatic performance.
Spectroscopy: Monochromator entrance/exit optics and spectrometer focusing modules.
Telecommunications: EDFA and WDM system collimation/focusing components.
