Description
Plano Convex Lens with Through Hole
The plano convex lens with through hole is a precision optical component designed for applications that require controlled laser transmission, optical focusing, and reliable operation in demanding environments. By combining a plano-convex optical surface with a precisely machined through hole, this lens allows a laser beam or optical path to pass through a designated area while maintaining the required optical function.
Jiujon Optics manufactures custom plano convex lenses with through holes for optical instruments, laser detection systems, industrial monitoring equipment, and high-temperature measurement applications. The lens can be manufactured according to the required optical performance, dimensions, aperture configuration, material, surface quality, and coating specifications.
Features of Plano Convex Lens with Through Hole
Plano-Convex Optical Design
The plano-convex configuration provides a positive focal length and can be used to collect, focus, or redirect light in optical systems. It is suitable for applications where a compact focusing element is required.
Precision Through Hole
The integrated through hole provides a defined optical passage for laser beams or other components within the optical system. The hole can be positioned and manufactured according to the customer’s mechanical and optical requirements.
Reliable Optical Performance
The optical surfaces are precision ground and polished to achieve the required surface quality and dimensional accuracy. Material selection and optical processing can be adjusted according to the wavelength and operating environment of the application.

Applications of Plano Convex Lens with Through Hole
The plano convex lens with through hole can be integrated into optical systems where focusing and controlled light transmission are required.
- Hot metal detection systems
- Laser-based industrial monitoring
- High-temperature measurement equipment
- Laser alignment and positioning systems
- Optical detection instruments
- Machine vision and inspection equipment
- Industrial sensing systems
- Custom laser optical assemblies
In hot metal detection applications, the lens can help provide a controlled optical path for laser-based detection and monitoring. Its through-hole configuration allows the optical system to accommodate a specific laser path or mechanical structure while maintaining the required optical alignment.
Materials and Optical Coatings
The choice of optical material depends on the operating wavelength, temperature, environmental conditions, and required optical performance. Jiujon Optics can manufacture plano convex lenses using suitable optical glass and fused silica materials according to project requirements.
Optical coatings can also be applied to improve transmission performance within a specified wavelength range. Anti-reflection coatings are available for different wavelength bands, while coating specifications can be customized according to the customer’s optical system.
For demanding industrial applications, material and coating selection should be evaluated together with the operating temperature, laser wavelength, power level, and environmental conditions.
Precision Manufacturing and Inspection
Manufacturing a plano convex lens with through hole requires control of both optical and mechanical parameters. Jiujon Optics uses precision grinding and polishing processes to produce the required optical surfaces while maintaining dimensional consistency around the through-hole structure.
Inspection can include dimensional measurement, surface quality inspection, optical performance testing, coating inspection, and interferometric measurement where required. Production and inspection procedures can be adjusted according to the tolerance and quality requirements of the optical assembly.
This manufacturing approach helps ensure that the through-hole position, lens geometry, optical surfaces, and overall dimensions remain consistent during production.
