Inspection Procedure

SUPERIOR® Optics tests every optical specification and provides complete inspection procedure and Certificate of Compliance (COC) for each production batch. Our manufacturing and QA inspection processes strictly follow ISO:9001:2015 standards, offering our customers a worry-free procurement experience.

The flow chart below illustrates the standard QA processes in a spherical lens production at our facility. An assigned QA manager oversees the production process and implement corresponding quantitative measurements at every step of production to ensure lens quality.

After the optics are completed, they are now ready for assembly. Our skilled assembly technicians employ a full range of metrology during assembly to finetune alignment precision and accuracy.

Furthermore, SUPERIOR® Optics conducts thorough testing to ensure that the assemblies we produce will meet or exceed the optical performance specifications required for your application needs. A detailed report on MTF plots, focal length, F#, chromatic aberration, and distortion will be provided.

Inspection Process for Precision Assembly

Our documentation includes all critical parameters; SUPERIOR® Optics’s packaging and labeling provides safe and accurate traceability for each batch shipment. A detailed inspection report including dimensional measurements, Zygo interferometry reports, and actual coating curves are provided along product shipment.

At SUPERIOR® Optics, as Inspection Procedure for Precision Assembly

Our optical engineers are aware of the need to create products that can be produced cost-effectively and meet or exceed your requirements. We are looking forward to working with you to create an optical design feasibility, and provide estimates for volume and prototype production.

Frequently Asked Questions

1. What are some optical considerations for camera module design?

f-number, object distance, fixed focus/autofocus, field of view (FOV), operating wavelength band, frequency range, MTF, scene dynamic range, distortion, chief ray angle (CRA), stray light requirements, and centration tolerances.

2. What are the advantages of vertical integration (VI) and design for manufacturability (DFM) in camera module manufacturing?

In camera module manufacturing, VI and DFM offer advantages such as intricate manufacturing (for complexly interrelating parts), rapid prototyping, scalability, and, most importantly, a path to continually reduced size, weight, power, and cost (SWaP-C).

3. What are the components of the optical assembly in camera module manufacturing?

Axial alignment, precise optical pathway placement, centration, electro-optics integration, optical bonding, and sonic welding techniques
