Precision Plano-Convex (PCX) Lenses for Focusing & Collimation
Positive Focal Length | Optimized for Infinite Conjugates | OEM Custom Integration
- Versatile Light Manipulation: Featuring one flat surface and one convex surface, PCX lenses have a positive focal length, making them the industry standard for collecting and collimating light, or focusing a collimated beam into a tight spot.
- Minimized Spherical Aberration: When oriented correctly—with the convex surface facing the collimated beam or infinite light source—plano-convex lenses significantly minimize spherical aberration, ensuring a sharper, tighter focal point for precision laser and imaging systems.
- High-Fidelity Surface Accuracy: Manufactured utilizing premium optical substrates and polished to strict surface irregularity tolerances (< λ/4 PV). This guarantees that the focused wavefront remains free from distortion, providing consistent energy distribution for demanding machine vision applications.
- 100% Export Compliant: Engineered exclusively for commercial automated optical inspection (AOI) and industrial instrumentation. Completely Germanium-free and tailored for civilian use, ensuring a restriction-free, highly stable global supply chain for your B2B manufacturing needs.

Product Overview
The Core Building Block of Optical Systems
Plano-Convex lenses are the most widely used optical elements for a reason. Their simple yet highly effective geometry makes them perfect for a vast array of applications, from basic illumination to complex laser beam delivery. Whether you are building a custom LED collimator for a machine vision light source or focusing a CO2 laser for industrial cutting, PCX lenses deliver reliable, predictable performance.
Maximized Photon Throughput
To ensure maximum energy transmission and prevent unwanted back-reflections, we offer highly customized multi-layer coatings. Depending on your specific substrate—whether it's UV Fused Silica for deep-ultraviolet applications, K9 glass for visible metrology, or ZnSe for industrial infrared systems—we can apply broad-band anti-reflective (BBAR) or specialized laser V-coats to maximize throughput.
Reliable, Ready-to-Integrate Optics
We understand that continuous B2B production relies on a predictable supply chain. We deliver globally compliant, tightly toleranced optical components directly to your factory floor or third-party integrators. With expertly chamfered edges to prevent chipping, our lenses are designed for safe and immediate integration into your optomechanical housings.
Application & Engineering Integration

Demonstrates exceptional anti-reflective performance with < 0.5% reflectance across the Near-Infrared spectrum (760nm – 1050nm), maximizing photon throughput for NIR lasers and optical sensors.
Metrology Analysis & Application Fit
- Target Wavelength: Broad compatibility from Deep-UV to Mid-IR, depending strictly on the chosen substrate and coating.
- Critical Orientation: For optimal performance (lowest optical aberration), the curved (convex) surface must face the longest conjugate distance. If focusing a laser, the convex side should face the incoming laser. If collimating an LED point source, the flat side should face the LED.
- Primary Applications:
- Focusing lenses for industrial laser processing and alignment.
- Collimators for high-intensity LED and machine vision illumination.
- Light collection elements in optical detectors and sensors.
- Imaging applications requiring simple magnification.
