The Workflow

Five Steps from Requirement to Delivery, Each with a Named Deliverable

Custom optics projects fail in the gaps between stages — a design that ignores tolerances, a prototype without data, a pilot that never proves process capability. Our five-step workflow closes every gap with a deliverable you can hold.

01

Requirement & Spec Review

You provide a target image, sample, drawing, or partial spec plus sensor and volume. We return a written feasibility and price band the same week — sensor match, optical budget, and a number your internal approval can use.

02

Design & Simulation

Optical lens design that survives manufacturing, not just the screen: Zemax-level prescription, MTF simulation, and tolerance analysis so the production lens still meets spec.

03

Prototyping

First articles built on production paths. You receive samples plus measured MTF, distortion, BFL and DOF — acceptance is a checklist, not an opinion.

04

Volume Production

From prototype performance to batch performance: ISO 9001 process control, 1 μm-class active alignment where the stack demands it, a prototype-to-mass-production schedule confirmed per project.

05

Delivery & Repeats

Shipment after 50% balance. Tooling stored free for 5 years so repeat orders skip spec review — the cycle returns at mass production, not at spec review.

60 days Then 30-day repeats

01 Cycle returns — repeat orders re-enter at mass production on the agreed framework schedule.

No Drawing? We Start from the Sample Itself

Optical systems routinely outlive their documentation. When the original supplier is gone and only stock samples remain, we reconstruct the optical prescription from the part in your hand — then validate the reproduction against it, side by side.

When this path applies: original supplier exited the market; drawings lost between product generations; a sub-assembly must be re-sourced without disturbing the parent system’s qualification; performance must be matched, then improved (e.g., tighter distortion) without redesigning the mount.

01 Measure — geometry and imaging performance benchmarked against the original (MTF, distortion); transmission and coating behavior measured on our UV spectrophotometer and interferometer stations.

02 Model — optical prescription reconstructed to Zemax-level design, with tolerance analysis applied as if it were a new design.

03 Validate — prototype verified side-by-side against the original sample before any volume commitment. Acceptance is the side-by-side step: your original sample and our prototype, measured on the same stations, reported in the same table.

Every reproduction project runs under NDA, with IP responsibilities defined in writing before work begins.

OEM or ODM — Both Run on the Same Discipline

OEM: we build to your released design. ODM: we carry the optical design responsibility from your requirement to validated production. Both run on the same five-step workflow, metrology, and commercial terms. What changes is where the design authority sits.

In scope: custom imaging lenses from spec or sample; opto-mechanical co-design and integration; reverse engineering & no-drawing reproduction; UV / DLP / spectral / laser optics per capability matrix.

Out of scope: retail / consumer single-piece sales; full camera electronics & ISP firmware; projects refusing NDA or IP terms; volume below sampling feasibility.

Design input checklist: image sensor (die or module — yours, or from our matched pool incl. OV9734 / OV2740 / ES101); field of view and working distance; resolution target (lp/mm or defect size); distortion limit; mechanical envelope; wavelength range (VIS / NIR / UV 365–405 nm) and environment. Send whatever exists — Step 01 completes this checklist in writing before any design hour is billed.

Designs Backed by Measured Data, Not Simulations Alone

Every design decision is closed with metrology: Trioptics centration systems, laser Fizeau interferometer, reflection-type centration, precision air-bearing platforms, UV spectrophotometer, and collimation stations — covering MTF, distortion, BFL, DOF, plus IP67 and IP68 environmental validation. As a precision optics partner, our answer to “will it hold in production?” is always a measurement record.

From Prototype Performance to Batch Performance

The question that ends custom projects is not “can you make one?” but “can you make ten thousand the same?” Three parts: ISO 9001 process control across the line, micron-class alignment capability applied wherever the design demands it, and per-batch test records that let your incoming inspection verify instead of trust. On the FA line, this discipline holds distortion below 0.05% with 10K+ batch consistency — the same standard carries into custom builds.

Extended Capabilities

Beyond Machine Vision Lenses

The same design-to-production chain also builds optics that never appear in a lens catalog. If your product needs light shaped, focused, projected, or split — this matrix is where to look.

Micro Projection Light Engines (DLP)

Projection optics engineered for DLP architectures across UV 365 / 385 / 405 nm wavelengths — where uniformity and thermal stability decide image quality.

How to Use This Matrix

Read the first column as a symptom, not a product. If your system projects, exposes, prints, senses spectra, or generates laser light, describe the light path outcome — we map it onto the capability above, or design beyond it.

Custom Optics FAQ

What Buyers Ask Before Sending a Spec

Before you ask a custom optics manufacturer for a quote, these are the questions that decide whether the project moves.

Capability — Can We Build It
Can you really work without drawings?
Yes. Our reverse-engineering path measures your sample, reconstructs the prescription, and validates the reproduction side-by-side against the original before any volume commitment.
How fast is the first substantive response?
An engineer replies within one business day, and a written feasibility and price band follows in the same week as receiving your spec, sample photo, or target image.
Do you co-design optical-mechanical assemblies, not just lenses?
Yes. Lens design and opto-mechanical integration are in-house under the same engineering team, so one responsible party owns the path from prescription to barrel.
Can you design around our own image sensor?
Yes. We design around your sensor die or module, including OV9734, OV2740 and ES101 micro CMOS targets already matched in our endoscope catalog.
Do you build optics beyond machine vision lenses?
Yes. The same design-to-production chain builds DLP projector light engines (UV 365/385/405 nm), UV exposure objectives (0.5 μm class), 3D printing telecentric lenses, reflection and acousto-optic spectrometer assemblies, and semiconductor laser modules.
What is the difference between OEM and ODM here?
OEM: we build to your released design. ODM: we carry the optical design responsibility from your requirement to validated production. Both run on the same five-step workflow and commercial terms.
Commercial & Verification
How is our IP protected?
An NDA is signed before any drawing, sample, or specification changes hands. Tooling is stored free for 5 years, and documentation ownership is defined in writing.
What are the payment terms?
50% deposit and 50% before shipment. Terms can be structured for long-term programs.
What MOQ applies to custom optics?
Sampling is supported at project stage; production MOQ is quoted per specification and annual volume.
How long from approved prototype to mass production?
a prototype-to-mass-production schedule is confirmed per project at quotation, and repeat orders follow the agreed framework schedule.
What does a prototype test report include?
Measured MTF, distortion, BFL and DOF data for every first article, produced on Trioptics centration, laser Fizeau interferometer and associated metrology stations.
What consistency data do you provide before mass production?
Pilot runs are documented with batch consistency data before scale-up, and every production batch ships with test reports.
