Lensmind runs an integrated optical manufacturing line: optical design, precision machining, thin-film coating, cementing and centration, cleanroom assembly, 1 μm-class active alignment, hermetic packaging and metrology-grade testing. The core steps are never outsourced — what we design, we build; what we build, we test.
Every outsourced step is a place where batch consistency goes to die. Click a stage: real floor photos, the named instrument, and the spec it protects — including 1 μm active alignment and Trioptics centration.
In-house optical and opto-mechanical design with MTF simulation and tolerance analysis, so every drawing is born manufacturable. Custom programs start here — including reverse engineering from physical samples when no drawing exists.
The same engineers who review your RFQ own the build through production. Custom optics programs →
Housings, barrels and optical seats machined to tolerances that preserve the lens cell’s alignment budget. Machined seats are what make later 1 μm active alignment meaningful rather than fighting a crooked foundation.
Capacity honesty: current throughput is discussed at quotation with real numbers — about 1,000 lenses per month on the current line, varying by family.
Coating runs on-site. Every run is verified by UV-VIS spectrophotometry — transmission, cutoff and curve shape — before elements touch assembly. VIS and NIR dual-band M12 configurations are produced here, not mixed from catalog parts.
Ask any supplier: “Who measures your coating, and can I see the spectrum from my own batch?” We can answer that with your batch number in hand. M12 NIR/VIS + FT/HT focus lock →
Cemented groups assembled in-house. Element tilt and decenter measured on a Trioptics centration system and monitored with a reflection-type centration meter. Measurement happens while the lens is still open — errors are corrected at the station, not scraped after the barrel is glued shut.
Centration error is the silent killer of MTF. Our FA machine vision lenses hold distortion below 0.05% in part because of this regime. FA machine vision lenses →
A live optical signal feeds back the stack’s actual axis; each element is repositioned on a precision air-bearing stage until measured performance peaks, then locked. That is the only practical route to OD < 2.0 mm endoscope objectives, and the physical basis of 10K+ batch consistency.
Hermetic packaging in Class 10,000 (ISO Class 7) cells: gas-tight sealing for autoclave cycling on medical builds, and IP67 / IP68 duty on industrial washdown optics. Medical-grade assembly is zoned apart from industrial production. Endoscope optics →
MTF, distortion, BFL, DOF and IP67 / IP68 validation on production instruments. Three mechanisms hold 10K+ unit batches inside the envelope: closed-loop 1 μm active alignment, ISO 9001 sampling and release, and per-batch data that trends before a complaint would. Batch test reports ship with the order — the same volume discipline our founders practiced at CASC-, Hikvision- and Sunny Optical-tier organizations.
Process data and test data share one batch number. See the full test matrix →
01 The line closes — a drift found at MTF traces backward, stage by stage, the same day.
A random photo pile proves nothing. Filter by process zone — the same order you will walk in Hangzhou, or on a guided video call with the engineers who run the line.
A scheduled walkthrough with the engineers who run the line: camera in hand, your questions answered live on the floor.
Welcome at Building 3, 2F, No. 1197 Tangcheng Street, Qingshanhu, Lin’an District, Hangzhou. Third-party pre-shipment inspection can be arranged.
