CUSTOM OPTICAL LENS MANUFACTURING FOR IMAGING & PROJECTION APPLICATIONS
Custom Imaging & Projection Optical Lenses Manufacturer in China
A projector lens with 1% barrel distortion makes straight lines appear curved. An LED collimating lens with an inconsistent beam angle creates uneven illumination across a batch. Imaging and projection lenses leave no room for error — every optical flaw shows up on screen or in the field.

What Sets Imaging and Projection Lenses Apart from Standard Optical Components
Imaging and projection lenses must produce a visually accurate image or illuminate a surface with a defined, uniform pattern. Distortion, field curvature, chromatic aberration, and illumination uniformity are all optical characteristics that end users can directly observe and evaluate — not just measure on an inspection bench.
ATRMOLD manufactures TIR lenses, Fresnel lenses, aspheric collimating lenses, magnifying lenses, and projection imaging components . From LED lighting optics to mini projector lenses, we combine in-house optical design with precision injection molding to deliver components that deliver consistent production performance.
💡
High Optical Efficiency
Optical-grade PMMA achieves ~92% transmittance. With AR coating, total system efficiency exceeds 95% for LED and projection applications.
📐
Low Distortion Design
Projection and imaging lenses are designed for<0.5% barrel distortion. Flat-field aspheric designs are available for document scanning and display applications.
🎯
Custom Beam Angle
TIR and Fresnel lenses support beam angles from 5° narrow spot to 120° wide flood. Custom illumination patterns are developed to meet your photometric requirements.
⚙️
Complex Surface Capability
Aspheric, TIR, and Fresnel surface profiles can be manufactured through precision injection molding.Diamond-turned tooling enables submicron groove and surface accuracy.

“We needed TIR lenses with a 15° beam angle for a commercial LED track lighting system — a tight spec our previous supplier could not hold in production. ATRMOLD redesigned the TIR profile and production samples hit 14.8° ±0.3° consistently. We have been running 80,000 pieces per month without a single beam angle complaint.”
