SWIR 2026: Quantum-Dot & Full-HD Sensors
INDUSTRY NEWS · INFRARED & SWIR IMAGING · SEPTEMBER 2026
Quantum-dot SWIR is being positioned to cost 60–70% less than today’s InGaAs route, while full-HD SWIR sensors and 8 µm micro-cores push resolution and size. Three developments that change what an infrared sourcing brief should ask for.
Short-wave infrared imaging is usually described as a capability waiting on price. In September 2026, three separate signals suggest that price is finally moving. A Korean quantum-dot sensor maker signed a camera-system partnership aimed at cutting SWIR cost by 60–70% against InGaAs; a European detector vendor listed a full-HD SWIR sensor; and a Chinese maker showed an 8 µm-pixel infrared micro-core. For buyers, each one changes a line in the specification.
Quantum-dot SWIR: a stated 60–70% cost cut versus InGaAs
On September 8, Korean quantum-dot sensor company SDT and optics manufacturer Green Optics signed an MOU to co-develop a quantum-dot (QD) SWIR camera system. The stated target is to bring cost down to roughly 30–40% of current InGaAs solutions — a reduction of 60–70% — for applications previously limited by price, including semiconductor inspection, agricultural sorting and security.
Treat this as a roadmap commitment, not a shipping price. An MOU indicates intent and joint development; it does not establish availability, performance parity, or qualification status. The practical implication for a buyer is that a QD-SWIR route is now plausible enough to put on a 12–24 month evaluation plan, and worth asking suppliers about directly — while staying with InGaAs for volume programs that need guaranteed, characterized performance today.
Full-HD SWIR joins the industrial catalogue
NIT, a LYNRED subsidiary, listed its SenS 1920 full-HD SWIR imaging solution, aimed at high-performance defense and security applications. The company’s SWIR matrix now spans qVGA through Full HD (1920×1080) and a 2K line-scan option (2048×1), with the full range scheduled for display around SPIE Sensors + Imaging and VISION Stuttgart in mid-September.
The significance is less a single part number than the direction: SWIR is filling out its resolution ladder. When a technology moves from hero sensors to a covered resolution range, it usually means the vendor expects multi-application volume. For integrators, that expands which inspection tasks can be specified as SWIR rather than visible or thermal.

The 8 µm micro-core: smaller packages, harder lenses
At CIOE 2026 (September 9–11, Shenzhen), Guide Infrared introduced the iTL1208, described as the industry’s first 8 µm megapixel infrared micro-core, at 22.6 × 22.6 × 34.5 mm and 34.5 g including a 12 mm lens. The same showing included the GAVIN1215MLC dual-band cooled core (medium-wave plus long-wave imaging from a single detector), a 650-series three-band sighting scope, and a thermal system quoted at 15 mK.
Smaller pixels are a system-level event, not just a detector spec. As pixel pitch shrinks from 12 µm toward 8 µm at constant resolution, focal lengths shorten and formats shrink — which tightens the tolerance budget on the infrared lens. MTF at higher spatial frequencies, coating uniformity across the band, and athermalization all become harder to hold. That is precisely where cheap lenses start to fail a good detector.
What to specify in your next infrared or SWIR brief
- Name the band and detector together. MWIR (about 3–5 µm) and LWIR (about 8–12 µm) drive different materials, coatings and focus architecture; a dual-band core needs coating performance stated per band.
- If evaluating QD-SWIR, ask for the maturity stage in writing. MOU, sampling, or volume? Ask for measured QE, dark current and a characterized wavelength range — not a target.
- For shrinking pixel pitch, specify MTF at the actual spatial frequency your detector requires, with field points, temperature and focus condition — not a generic “high MTF” claim.
- Lock athermalization as a system claim, covering housing, optical material, detector position and the stated temperature range.
- Request inspection evidence up front: which parameters need a measurement report, for sample, batch, or every part.
