Industry news

In the past decade, the application of infrared sensors has moved from military equipment to civilian daily use, forming a huge industrial system from night vision security and industrial temperature measurement, to thermal imaging mobile phones and contactless medical care. Today, the industry's attention is rapidly focusing on a new direction - hyperspectral infrared imaging (Hyperspectral IR Imaging).

This is not a simple pixel upgrade, but an innovation in the spectral dimension.

What is "hyperspectral" and why is it worth paying attention? Traditional infrared thermal imaging often focuses on the 8-14 μm band, and outputs temperature images. But hyperspectral systems can analyze the "spectral fingerprint" of the material itself in dozens or even hundreds of bands, and have stronger recognition capabilities.

This means:

It can not only "see a person", but also determine the moisture content of his skin

It can not only "detect a piece of material", but also identify whether it is PE or PET

It can not only "monitor the temperature of the fire source", but also analyze its chemical composition

Such capabilities will bring revolutionary changes in agricultural testing, medical diagnostics, environmental monitoring, security identification, intelligent driving and other scenarios.

technical difficulties? The "multitasking challenge" of optical systems Infrared hyperspectral is not as simple as "adding a few filters", it places higher requirements on the entire system:

Multi-band optical path fusion: How to carry multiple bands in a compact module to avoid mutual interference?

Material Penetration and Imaging Differences: The refractive index of different infrared bands for plastics, glass, skin and other substances varies greatly, and the lens material must be highly matched.

Surface shape and coating synergy are complex: traditional single-wave coating solutions cannot be used, and reflection suppression and band enhancement must be carried out for multiple bands. Observation and advance layout of

Aubor As a manufacturer of deep-rooted infrared optical systems, Aubor has been exposed to high-band requirements (such as 1550nm/1650nm) in multiple customer projects, and has built a foundation of capabilities in materials science and free-form surface structure.

We believe that:

polymer lens will become an ideal platform for multi-band systems, with higher molding flexibility and band adaptation elasticity;

nano-structure coating + non-spherical structure joint optimization will become the core means of future high-end modules;

from "single lens" to "subsystem synergy", is the real value of optical design landing point.

Hyperspectral is not the black technology of the future, but is approaching the practical "next threshold".
At Aubor, we continue to pay attention to this trend and are willing to explore together with the upstream and downstream of the industrial chain, how to make infrared systems not only "see", but "understand".
