High Precision PCX Plano-Convex Lenses with Anti-Reflective Coating

High Precision PCX Plano-Convex Lenses with Anti-Reflective Coating

1. Material & Construction

• Substrate Materials: Optical glass (BK7, B270), Fused Silica (UV-grade), or Optical Plastics (PMMA, PC).

• Coating Type: Single-layer (e.g., MgF₂) or multi-layer dielectric Anti-Reflective (AR) coatings.

• Design: One plano (flat) surface and one convex (spherically curved) surface.

2. Key Properties

• High Precision: Tight tolerances on focal length, diameter, center thickness, and surface quality.

• Low Aberration: Corrects for spherical aberration when used correctly (light incident on convex side).

• High Transmission: AR coating drastically reduces Fresnel reflection losses, often to <0.5% per surface.

• Enhanced Contrast: Coating minimizes ghost images and flare by suppressing surface reflections.

• Wavelength Specific: Coatings are optimized for specific ranges (e.g., Visible, NIR, UV, or Laser lines like 532nm, 1064nm).

3. Primary Functions

• Focusing: Converges collimated light to a precise focal point.

• Collimating: Converts a point light source into a parallel beam.

• Light Collection: Efficiently gathers and directs light in optical systems.

4. Common Applications

• Laser Systems: Beam focusing, collimation, and delivery in material processing, medical, and fiber optic devices.

• Imaging & Machine Vision: Singlet lenses in cameras, sensors, scanners, and barcode readers.

• Optical Instrumentation: Core components in spectrometers, projectors, telescopes, and interferometers.

• Sensing & Detection: Used in LiDAR, biometric sensors, and analytical measurement equipment.

• Life Sciences: Fluorescence microscopy, flow cytometry, and DNA sequencing instruments.
