ラテラルフロー試験(LFT)

当社は、ラテラルフロー試験(LFT)を改善する光学読取方式を開発しました。LFTはシンプルな設計で必要な精度が得られるのが主な理由で、広範に利用されています。そのため、低コストで大量に試験を実施できます。LFTは小型で携帯でき、簡単に使用できます。現時点におけるLFTの主な短所には、感度の限界、信号定量化の難しさ、単回使用ではなく多重分析を行える検出の確立が挙げられます。こうした問題を克服するため、当社はLFTの性能を改善する小型で低コストな光学モジュールを開発しました。

本技術は光学感度を改善し、多重分析を可能にし、反射測定や蛍光測定といった様々な光学測定方式に対応できます。分光センサーを内蔵するamsの光学モジュールは、LFTへ統合できます。

この専用光学モジュールは、分光検出技術に基づいています。この分光検出チップ、AS7341を使用する場合は、amsのライセンスとサポートを取得済みの必要があります。価格とサポート情報については、当社までお問合せください。

Spectral Sensing Spectroscopy

Optical spectroscopy is typically associated with expensive spectrometer devices that cost tens to hundreds of thousands of dollars.

ams, a leader in analog and optical sensing technology, has brought spectroscopy down to the chip-scale. By essentially innovating a spectrometer-on-a-chip approach, ams spectral sensors enable all new types of applications and use cases.

Advanced Nano-Optic Interference Filter Technology

With our leadership position in ambient light and optical sensing in the mobile phone space, ams has decades of experience in optical packaging innovation, delivering compact, high-precision and cost-effective spectral sensor solutions for all types of applications.

The core innovation behind this cost-effective spectrometer-on-a-chip approach is nano-optic interference filter technology as part of the silicon layering manufacturing process. 

High-precision process technology enables us to create bandpass and blocking filters optimized for different sensing requirements. The inorganic filters provide thermal stability and longevity, enabling highly accurate designs that were not possible previously.

Precision Color and Light Sensing

Our technological advancements in optical filters and ultra-sensitive photodiodes produce “better than the eye” levels of color sensing at consumer price points. The ams spectral sensing roadmap includes Near-Ultraviolet, Visible and Infrared devices backed by manufacturing capacity to mass-produce in the volumes needed mobile phones, consumer, health and industrial devices. 

ams offers a wide range of spectral sensing technology, like the AS7341, an 11-channel VIS spectral sensor enabling multiple applications like color matching and analysis, spectral power characterization, and spectral signature analysis.

Multi-Spectral, Hyperspectral and Near-IR

Sensing in the multi-spectral realm does not just mean “seeing” wavelengths outside the range of human vision, but seeing things differently. The light composition can be analyzed to reconstruct the characteristics of light and deconstruct individual data points creating new analytical perspectives. 

When combined with machine learning and neural networks, artificial intelligence approaches enable spectral data to be used to reveal what the human eye could never see. Chip-scale spectral sensing from ams makes this possible. This technology can be used to measure an ever-increasing range of conditions from the moisture content of food, or hydration levels of the human body to analyzing the type of fabric being placed in the washer.

Spectral Sensing Enabling New Applications
