Infrared Lens Shift: A White-Light OEM
INDUSTRY NEWS · INFRARED OPTICS · SEPTEMBER 2026
Huaguo Optics spent three decades making white-light lenses as an OEM for Canon and Panasonic. In August 2026 its output value and sales value each passed CNY 100 million, January–August revenue was up 77%, and infrared thermal imaging is now the mainstay. Infrared lens supply has a new kind of competitor.
Infrared lens manufacturing has historically been a specialist business: low volumes, expensive materials, and a handful of workshops that know how to diamond-turn germanium and mould chalcogenide glass. That is changing. Huaguo Optics, founded in Foshan in 1992, built its early business as an OEM manufacturer of white-light lenses for brands including Canon and Panasonic. From 2021 it began withdrawing from lower-margin legacy orders and moved its precision optical processing, quality control and volume delivery capability into infrared thermal imaging. The reported result: August 2026 output value and sales value each exceeded CNY 100 million, January–August revenue rose 77% year on year with profit roughly doubling, and the full-year revenue target is CNY 950 million.
From white-light OEM to infrared: what actually transferred
The interesting part is not that a lens company changed product lines. It is which capabilities transferred. A white-light OEM business is built on exactly the disciplines that infrared manufacturing is short of at scale: tight dimensional control on high volumes, statistical process control, incoming-material discipline, and the delivery reliability that comes from serving consumer-brand supply chains where a missed shipment is a contractual event.
Infrared adds three things on top of that: different materials (germanium, silicon, chalcogenide glass, zinc selenide), different manufacturing methods (single-point diamond turning for aspheric and diffractive surfaces, precision moulding for chalcogenides), and athermalisation — the mechanical design that keeps focus stable as the housing and the lens materials expand and contract at different rates over temperature. A repurposed white-light manufacturer does not automatically get those right. It gets them by hiring, tooling and accumulating process data — which is what the equipment investment below describes.
What the numbers say
- August 2026: output value and sales value both above CNY 100 million.
- January–August 2026: revenue up 77% year on year; profit roughly doubled.
- Full-year target: CNY 950 million revenue.
- Mix: infrared products and derivatives are now the absolute mainstay of the business; industrial temperature measurement and automotive lenses are the application segments with the highest share of value.
- Equipment: a ladder of nearly 600 ultra-precision processing machines covering different apertures, plus self-developed automation aimed at “small batch, multiple varieties” infrared production.
That last point is the one to dwell on. Infrared optics has a structural contradiction: the parts are expensive, the volumes are low, and every customer wants a different focal length, F-number and package. It is the opposite of the economics a white-light OEM was built for. Building automation around quick changeover rather than around a single high-volume line is the only way the arithmetic works — and it is precisely the capability that decides whether a supplier can hold a two-week lead time on a 30-piece order without pricing it as a prototype.

What it means for infrared lens buyers
- More competition in standard assemblies. Industrial thermometry and automotive night-vision modules are the volume applications pulling this capacity. Expect improving delivery and price on standard MWIR and LWIR lens assemblies.
- Custom athermalised designs stay specialist. A supplier entering from white-light optics still has to prove temperature-stable focus over the full operating range. Treat that as a validation item, not a datasheet claim.
- Material risk has not gone away. Germanium supply and pricing, silicon availability and chalcogenide moulding yields drive cost more than machining time does. Ask which material the design assumes and what happens if it moves.
- Multi-variety automation changes MOQ conversations. Suppliers who have genuinely solved quick changeover can quote sensible terms below the volumes that specialist workshops require.
Infrared lens RFQ checklist
- State the waveband first: MWIR (3–5 µm) or LWIR (8–12 µm). Our MWIR versus LWIR RFQ guide walks through the detector-side choices that follow from it.
- Give the detector pixel pitch and F-number before discussing price — they determine whether the lens can be made at all.
- Ask whether the design is athermalised, over what ambient range, and by which mechanism (passive mechanical compensation versus active focus).
- For moulded chalcogenide or silicon elements, request the moulding process, mould life, surface form error and roughness limits.
- For diamond-turned germanium aspheres, ask about tool marks, mid-spatial-frequency error and how the anti-reflective coating behaves over those surfaces.
- Request per-element transmission data rather than an assembly-level figure, plus the coating durability test method.
- Confirm whether the lens ships as an assembly with the barrel and to which mechanical interface standard.
- Confirm the export-control status of the lens and any detector with your supplier for your specific destination market.
Sourcing infrared lenses from China?
TUOLAN TRADE helps overseas buyers specify infrared lens assemblies by waveband, detector and athermalisation requirement, compare suppliers on measurable optical data, and coordinate samples, inspection and export documentation. Send your requirement to sales@tuolango.com.
Specify handheld low-light observation optics separately
For handheld low-light observation projects, review the model-specific KE902501 25 mm 10× eyepiece and KN902501 25 mm F/≤1.23 objective lens in TUOLAN’s visible-optics catalog. These are optical components for integration into a complete viewing system. Confirm the image-intensifier or detector format, spectral response, optical spacing and mechanical interfaces for the project; thermal-imaging lens requirements follow a separate specification. These catalog references do not identify the manufacturer discussed in this report.
