10 ways beyond-visible light is reshaping industries

01 / 10

Non-invasive glucose monitoring

SWIR 1050/1400–1650nm absorption bands enable needle-free blood glucose measurement. FTIR-analogous technology opening the wearable healthcare market.

02 / 10

Gas sensors (CO/CO₂)

We review NDIR light-source requirements using distinct 3.1–4.3μm MWIR R&D and 2.1–2.3μm extended-SWIR product ranges.

03 / 10

Alcohol sensors

Contactless alcohol measurement via 1050 · 1300–1500nm SWIR. Breathalysers, food-process quality control.

04 / 10

Food & agriculture QC

1460nm water band and 2900nm lipid band enable non-destructive measurement of fruit sweetness, dairy fat, and grain moisture.

05 / 10

Semiconductor wafer inspection

1300nm SWIR penetrates silicon for non-destructive backside defect inspection.

06 / 10

Autonomous driving & ADAS

IR/SWIR perception in night and fog conditions; LiDAR auxiliary light sources.

07 / 10

Watches & wearables

Heart rate, blood flow, biometric authentication — low-power IR LEDs for next-gen wearables.

08 / 10

Anti-counterfeiting & security

Invisible markings on banknotes, passports, luxury goods. SWIR imaging for authenticity verification.

09 / 10

Machine vision & robotics

IR LEDs enable object recognition in low-light or noisy environments, pick-and-place, automated inspection.

10 / 10

Water, air & surface sterilisation

UVC 265–280nm / UVB 308–325nm LEDs deliver mercury-free sterilisation for fish farms, purifiers, HVAC.
