1、 Collect Sample Technical Requirements
Submit your full optical technical parameters, including substrate material (sapphire, fused silica, BK7), dimensional tolerance, surface flatness, transmittance demand, AR coating types and custom CAD drawings. We will also record personalized requirements such as laser engraving, logo marking and dedicated packaging standards.

2、 Generate Professional 2D & 3D Optical Drawings
Our optical R&D team develops precise 2D production drawings and 3D simulation renderings according to your specifications. All design drafts will be sent to you for review and written confirmation before sampling.

3、 Sample Payment & Optical Raw Material Preparation
After sample fees are fully confirmed and settled, our warehouse allocates high-purity optical blanks, coating films and auxiliary processing materials strictly following your technical standards.

4、On-Site QC Supervision During Sample Machining
Our quality control engineers track the whole CNC grinding, ultra-precision polishing and coating production process. Real-time inspection is implemented to avoid dimensional errors and surface defects.

5、Comprehensive Optical Performance Inspection
All finished samples go through strict lab testing: surface roughness detection, spectral transmittance test, flatness measurement and dimensional tolerance verification. Only defect-free samples can enter the delivery link.

6、Shipment & Detailed Delivery Notification
Qualified optical samples are packed with shockproof anti-scratch optical packaging and delivered by international express. We will email you the logistics tracking number, original sample inspection report and real shooting photos of finished samples.
