Direct from our Shenzhen automated manufacturing center. Explore our flagship optical sub-assemblies and camera modules engineered with custom Plano-Convex and low-distortion lens systems.
In modern optoelectronics, imaging systems, and photonic devices, the Lente Plano Convexa (Plano-Convex Lens) remains a foundational transmissive optical element. Engineered with one flat (plano) surface and one outward-curved spherical (convex) surface, these lenses feature a positive focal length ($f > 0$) designed to collect, focus, and collimate light in monochromatic and broadband applications.
As a leading ODM Lente Plano Convexa Manufacturer & OEM Factory headquartered in Shenzhen, Shen Zhen You Xiang Da Technology Co., Ltd. (YXD Optics) combines advanced glass blank pressing, sub-nanometer CNC polishing, and high-vacuum Broadband Anti-Reflective (BBAR) coating technologies. We empower tier-1 optical system integrators, camera module designers, and biomedical device manufacturers with customized lens optics tailored to demanding performance tolerances.
Optical Principle: To minimize spherical aberration when focusing infinite conjugate light, the curved surface of the Plano-Convex Lens should always face toward the incident parallel beam or the infinite conjugate distance. This distributes light refraction evenly across both surfaces.
Combining Shenzhen's world-class electronics supply chain with fully automated optical fabrication techniques to guarantee rapid prototyping, scalable mass production, and strict cost performance.
Our factories employ high-speed CNC spherical generators and Magnetorheological Finishing (MRF) units capable of achieving surface roughness ($Rq$) under 0.5 nanometers, eliminating sub-surface damage in high-power laser applications.
Optical lens elements and micro-camera modules are assembled within ISO Class 5 (Class 100) laminar flow clean booths. Automated ultrasonic washing guarantees microscopic cleanliness prior to optical cement bonding or barrel mounting.
From raw optical glass procurement (CDGM, Schott, Ohara, Corning) to SMT sensor placement, active alignment, and final MTF testing, YXD provides a seamless, risk-free ODM manufacturing lifecycle for global OEM buyers.
Exploring how advancements in metasurfaces, hybrid molded glass-plastics, and ultra-short pulse laser coatings are reshaping the optics industry.
Traditional Plano-Convex lenses encounter inherent chromatic aberration across multi-spectral wavelengths. YXD's forward-looking R&D team is integrating flat sub-wavelength nanostructure arrays (metasurfaces) onto the plano surface of glass substrates. This hybrid approach enables broadband chromatic aberration correction while preserving high optical throughput for compact LiDAR and AR/VR head-mounted displays.
As industrial picosecond and femtosecond laser processing expands into semiconductor manufacturing, Plano-Convex focusing lenses require exceptional Laser-Induced Damage Threshold (LIDT) ratings. Our factory utilizes Ion-Beam Sputtering (IBS) to produce hard metal-oxide thin films achieving LIDT > 15 J/cm² @ 1064nm (10ns pulse width), eliminating thermal lensing effects.
To survive extreme thermal fluctuations (-40°C to +125°C) in automotive ADAS camera modules, precision glass molding is rapidly replacing traditional plastic optics. Molded Plano-Convex element designs offer high refractive index stability ($dn/dT$) and zero moisture absorption, crucial for vehicle environmental compliance.
Medical endoscopes demand micro Plano-Convex elements down to $\varnothing 1.0\text{ mm}$ with strict biocompatibility. YXD leverages precision centerless grinding and automated optical cement dispenser systems to manufacture biocompatible, sterilizable miniature lens components for minimally invasive surgical tools.
How specialized Plano-Convex lens geometries and custom optoelectronic module designs drive performance across mission-critical sectors.
LiDAR emitters rely on UV Fused Silica Plano-Convex lenses for laser beam expansion and collimation. With tight focal length tolerance ($\pm 0.5\%$) and AR coatings at 905nm or 1550nm, our lenses maximize photon return efficiency over long detection ranges.
Automated optical inspection (AOI) tools require low-distortion illumination systems. By integrating custom Plano-Convex collector optics with high-speed industrial camera modules, system integrators achieve edge-to-edge illumination uniformity across fast conveyor lines.
Facial recognition access terminals and video doorbells integrate small-form-factor fixed focus and autofocus lens modules. Our custom Plano-Convex element stacks maximize light throughput in low-light infrared environments.
Comprehensive standard engineering tolerances for OEM/ODM Plano-Convex Lens customized orders. Every parameter is verified using Zygo Interferometers and Trioptics metrology devices.

A Lente Plano Convexa (Plano-Convex Lens) is a positive optical element featuring one flat surface and one convex spherical surface. It is ideal for focusing parallel rays of light into a point (infinite conjugate applications) or collimating light from a point source. It is widely used in laser collimation, projection systems, optical imaging detectors, and industrial camera lens assemblies.
The effective focal length ($f$) is determined by the Lensmaker's Formula:
$\frac{1}{f} = (n - 1) \cdot \left( \frac{1}{R_1} - \frac{1}{R_2} \right)$
For a Plano-Convex lens where the flat side has infinite radius ($R_2 = \infty$), the equation simplifies to: $f = \frac{R_1}{n - 1}$, where $R_1$ is the radius of curvature of the convex surface and $n$ is the refractive index of the glass substrate at the design wavelength.
To minimize spherical aberration, the curved (convex) surface should face toward the collimated beam or the infinite conjugate distance. When focusing a parallel light beam down to a focal spot, point the curved side toward the light source. Conversely, when collimating a point source placed at the focal point, point the flat side toward the point source.
