The Shanghai Quality Assurance Center

In order to realize our goal of 100% meeting or exceeding customer requirements on all custom-manufactured products, the Importoptics.com team has established a Quality Assurance Center within Xuhua.  This center, headed by a senior technician with 40 years of optical manufacturing experience, takes the lead on:


Maintaining and ensuring use of current revisions of all drawings


Enforcing manufacturing time schedules, in consultation with the Chief Engineer


Managing stock control over limited life items


Ensuring regular calibration of testing equipment


Supervising ongoing in-process product inspections


Carrying out final product inspections


Managing separation of rejects and reworks, if any


Maintaining Statistical Process Control (SPC) records


No Import Optics product leaves China without full inspection in the Quality Assurance Center.  The Center takes responsibility for:

1. Basic Inspection of Optical Elements, including:

  1. Element surface quality: Inspection covers Power/IRR, scratch/dig, bubbles, beveling and cementing, and a review of uniformity and resistance of coating, if any

  2. Dimensions: Inspection covers diameter, radius, sag, and thickness.

2. Packaging inspection, including:

  1. Packing standards: Inspection of invoices, part numbers and numbers of parts and assemblies, to ensure that invoice and shipping marks agree with contents.

  2. Packaging quality: Inspection of packing materials to ensure the shipment is protected against moisture, jostling, weight, dust, and other threats in international shipment. Where customer PO specifies special packaging requirements, the center inspects to ensure those requirements have been met.

Where additional/specialized inspection is required, the Import Optics team will cooperate with a U.S. Quality Partner to ensure all customer requirements are met or exceeded.
