    Custom-Made Plano Convex Lens for Collimator Optical Systems



    Custom-Made Plano Convex Lens for Collimator Optical Systems


    1. Material

    • Core Substrate: Precision-engineered optical glass (e.g., BK7, Fused Silica, N-BK10) or specialized crystals (ZnSe, Ge) for IR applications.

    • Coatings: Custom Anti-Reflection (AR) coatings optimized for target wavelengths (UV-VIS-NIR/MIR), minimizing reflection losses (<0.5% per surface).


    2. Key Properties

    • Surface Accuracy: λ/10 to λ/2 surface flatness (plano side) and λ/4 to λ/10 wavefront distortion (convex side).

    • Precision Tolerances: Tight control on focal length (±1%), center thickness (±0.02mm), diameter (+0/-0.025mm), and centration (<1 arcmin).

    • Low Aberration: Minimized spherical aberration via optimized convex curvature.

    • Laser Damage Threshold: High LIDT (>5 J/cm² @ 1064nm) for laser collimators.

    • Thermal Stability: Low CTE materials (e.g., Fused Silica) for temperature-sensitive environments.


    3. Primary Function

    • Beam Collimation: Transforms diverging light (from point sources like LEDs, lasers, or fiber optics) into a parallel beam with minimal divergence.

    • Wavefront Control: Maintains phase uniformity across the collimated beam.

    • Focal Length Matching: Precisely engineered to pair with light sources at specific working distances.


    4. Critical Applications

    • Laser Collimators:

      • Alignment systems (construction, astronomy).

      • LiDAR modules for autonomous vehicles.

      • Laser cutting/engraving beam delivery.

    • Fiber Optic Communications: Collimating output from SMF/MMF fibers.

    • Interferometry & Metrology: Creating reference wavefronts.

    • Spectral Analysis: Illumination in spectrometers.

    • Medical Devices: Endoscope illumination, OCT systems.

    • Defense/Aerospace: Targeting systems, IR countermeasures.
