In the daily R&D and procurement work of optoelectronic equipment, practitioners are frequently confronted with various customization and adaptation challenges: exclusive substrate and surface profile parameters required for different application scenarios, sample testing demands in the early R&D stage, consistent and stable product quality during mass production, as well as full test reports to verify all precision indicators. To streamline the whole process of optical component selection, sampling and bulk procurement, partnering with a source manufacturer with a complete in-house R&D and production chain can greatly boost communication and execution efficiency.
With years of dedication to the manufacturing of precision optical components, Changchun Boxin Photoelectric Co., Ltd. has established an integrated production system covering the R&D, machining and testing of cylindrical lenses. We provide customized cylindrical lens manufacturing and supporting services for customers engaged in laser equipment, machine vision, medical endoscopes, scientific research instruments and other fields.
I. Comprehensive Processing Equipment to Meet Diverse Grinding Requirements
Reliable processing hardware lays a solid foundation for fundamental lens quality. The company is equipped with more than 100 sets of CNC cylindrical lens grinding and polishing machines, plus over 40 sets of conventional polishing equipment, capable of fine grinding and polishing cylindrical lenses with various curvatures and dimensions. Workpieces ranging from miniature small-size prototypes to large-format industrial lenses can all be fabricated strictly in accordance with design drawings.
II. Professional Testing System for Quantifiable Verification of All Precision Parameters
To guarantee the machining accuracy of every product, our factory is equipped with a full suite of high-precision testing instruments:
• ZYGO laser interferometer fitted with diffractive lenses for various radii, applied for surface figure accuracy inspection;
• Self-calibrated and automatically computer-controlled cylindrical lens measuring instrument to complete generatrix, verticality and inclination angle measurement. All test data can be stored and printed for file keeping, enabling full traceability of product specifications and convenient inspection & acceptance for clients.
III. Extensive Customizable Parameters for Multi-Wavelength Application Scenarios
In response to the operational requirements of various industrial equipment, we offer multi-dimensional flexible customization with standardized specifications as follows:
1. Wide Range of Substrate Options
Available materials include colorless optical glass, fused silica, laser crystals, radiation-resistant glass, dedicated UV/IR materials. We also process crystal materials such as SiO₂, CaF₂, BaF₂, ZnSe and ZnS, covering the full spectrum from visible light, near-infrared to far-infrared bands.
2. Broad Size Specifications
• Radius of curvature: R2 to Infinity
• Overall outline dimension: 2 mm ~ 1200 mm, maximum processing width: 650 mm
3. Standardized Tolerance & Optical Indicators
• Outline tolerance: ±0.01 ~ ±0.2 mm
• Thickness tolerance: ±0.01 ~ ±0.2 mm
• Surface quality: 10/5 ~ 80/50
• Surface figure accuracy:λ/20～λ/2 / Φ100 mm
• Decenter:30″～5′(or Δt ≤0.01)
• Effective clear aperture: ＞90%
4. Custom Optical Coatings on Demand
Various optical films can be customized according to actual working conditions to meet anti-reflection, high-reflection, beam splitting and other functional requirements.
IV. Flexible Production Scheduling for Both Prototyping and Mass Delivery
Backed by mature assembly lines, our annual output reaches 2 million pieces, supporting orders of all volumes flexibly:
• At the early R&D phase, small-batch sample fabrication is available for customers to conduct machine testing and solution verification;
• Once the design is finalized for mass production, stable scheduled delivery will be arranged to ensure consistent lead time and uniform quality across all batches.
V. One-Stop Supporting Services to Simplify Procurement Procedures
All procedures are completed in-house in a closed-loop workflow, including drawing confirmation, material selection, precision grinding, accuracy inspection, optical coating and packaging & shipment, eliminating the need for multi-party coordination and intermediate outsourcing. Our technical team assists customers in sorting out selection demands and recommending suitable solutions based on equipment operating environments. Complete test documentation is provided for each batch for warehouse acceptance and quality archiving, effectively lowering overall procurement coordination costs.
If you are currently selecting cylindrical lenses, requesting prototype sampling or placing bulk orders, please feel free to contact us. We will provide tailored technical solutions and quotations based on your detailed requirements.
We look forward to cooperating with all partners in the optoelectronics industry and driving the steady upgrading of optoelectronic equipment with high-quality precision optical components.
