R&D designers of optical equipment often encounter obstacles in lens selection during project development. Traditional spherical lenses tend to generate optical aberrations such as field curvature and distortion, requiring multiple stacked lenses for optical path compensation, which increases overall equipment size and assembly costs. Although spherical components feature manageable processing control, batch parameter fluctuations extend equipment debugging cycles. Furthermore, surface defects on lenses and insufficient weather resistance of coatings undermine long-term operational stability of optical devices.
Drawing on years of experience in precision optical design and fabrication, Boxin Optics launches a full range of self-developed toroidal lenses. Equipped with imported precision processing equipment, a complete inspection and quality control system, and large-scale production lines, we deliver integrated optical solutions covering four core dimensions: optical performance, customization capacity, mass delivery and standardized quality control. Our products serve diverse scenarios including machine vision, laser beam shaping, spectrometers, medical inspection and scientific optical platforms.
Boxin toroidal lenses support full-range flexible customization with various substrates, sizes and high-precision specifications:
1. Extensive Optional Substrates We process colorless optical glass, fused silica, laser crystals, radiation-resistant glass, UV/IR exclusive materials, calcium fluoride, barium fluoride and other metallic optical materials, covering full wavebands from visible light to far infrared.
2. Flexible Adjustable Sizes & Curvatures
· Radius of curvature: Customizable from R30 to infinity
· Outline dimensions: Φ10–Φ300 mm; maximum non-circular machining dimension: 300 mm
· Tolerance control: Outline and thickness tolerances stably maintained within ±0.01~±0.2 mm
3. High-Standard Optical Specifications
· Surface quality: Multiple grades from 10/5 to 80/5 available for scientific research and industrial mass production
· Surface figure accuracy: λ/4 ~ λ over Φ100 mm, verified by professional precision testing equipment
· Decenter accuracy: 30 arcseconds to 5 arcseconds (Δt ≤ 0.01), effectively lowering optical path debugging difficulty
4. Custom Coating Matching Custom coatings such as aluminum coating, silver coating, dielectric high-reflection films and anti-reflection films are available per working spectrum, featuring outstanding adhesion, temperature resistance and weather resistance.
Our in-house full-process manufacturing covers grinding, polishing, inspection and coating with fully controllable workflows backed by complete hardware infrastructure:
1. Imported Professional Processing Equipment Over 30 sets of European original imported toroidal dedicated grinding and polishing machines perform refined zonal polishing for bi-curved differentiated surfaces, optimizing edge surface accuracy to deliver premium toroidal lenses.
2. High-Precision Inspection Laboratory Zygo laser interferometers serve as core surface figure testing devices. Holographic measurement lenses are equipped for special-specification products to fully capture optical data including surface profile, reflectivity and contour. A complete Certificate of Conformance (COC) is provided for every batch for warehouse inspection and project filing.
3. Large-Scale Stable Production Capacity Annual output of toroidal lenses exceeds 150,000 pieces. Flexible production scheduling enables fast turnaround for urgent R&D samples and long-term stable bulk orders for equipment manufacturers, eliminating production schedule delays caused by supply shortages.
4. Standardized Dust-Free Coating Workshop We operate in-house Leybold vacuum coating machines under unified cleanroom operating protocols. Lens cleaning procedures are elaborately managed to strictly suppress scratches and defects, ensuring ultra-high lens cleanliness, eliminating coating flaws in upstream processes and stabilizing finished product yield.
1. Optimized Optical Path Structure to Cut Comprehensive Equipment Costs Our exclusive optimized bi-curved structure simultaneously corrects astigmatism, field curvature, imaging distortion and other optical errors. Under identical imaging standards, fewer stacked spherical lenses are required, reducing equipment volume and weight, cutting structural component machining and assembly steps. Material and assembly costs are effectively controlled, delivering uniform, clear wide-field imaging with enhanced resolution and contrast.
2. Stable Mirror Quality for Long-Term Complex Operating Conditions Elaborate full-process grinding and polishing strictly suppress surface imperfections including scratches, pits and stains. Custom coatings boast strong adhesion with minimal reflectivity attenuation under high-low temperature and humid environments, ensuring superior long-term stability for outdoor and continuously operating industrial equipment.
3. Excellent Batch Consistency to Shorten Equipment Debugging Cycles Standardized mass fabrication unifies curvature, decenter and surface figure parameters within each batch, boosting optical path commissioning efficiency and reducing man-hours from repeated adjustments. Consistent yield eliminates extra costs from reorders and replacements to guarantee on-time project delivery.
4. One-Stop Full-Service Support OEM/ODM drawing customization is supported. Our technical team collaborates on optical path optimization and coating matching. Independent shock-resistant protective packaging minimizes damage during long-distance transportation for superior intact delivery rate.
Our lenses are widely applied in medical bio-analyzers, machine vision inspection equipment, laser beam shaping systems, infrared spectrometers, precision scanning devices, and scientific optical platforms for universities and laboratories. We offer matched precision and budget solutions for both small-batch prototype R&D and long-term mass equipment supply.
When selecting lenses, comprehensive evaluation of unit price, optical path debugging loss, product scrap cost, delivery lead time and supporting inspection documents is recommended to assess the total cost of equipment ownership. With years of expertise in precision optical processing, Boxin Optics standardizes the full high-precision toroidal lens manufacturing workflow to balance optical performance, stable yield and delivery efficiency:
