Custom-Made Plano Convex Lens for Collimator Optical Systems
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).
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.
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.
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.
