Lateral Flow Testing (LFT)

We developed an optical readout for improved Lateral Flow Testing (LFT). The widespread use of the LFT is mainly attributed to its simplicity of design and relevant accuracy, which allows these tests to be produced in a cost-effective way at high volumes. LFTs are compact, portable and easy to use. The current drawbacks to LFT include limitation in sensitivity, difficulty of signal quantification, and multi-analyte detection rather than single use case. To address this, we developed a small and cost-effective optical module to improve the performance of LFTs. To find out more download our factsheet.

The technology increases optical sensitivity, allowing multi-analyte detection, and accommodating different optical measurement methodologies such as reflection and fluorescence measurements. The ams optical module, containing a spectral sensor, can be integrated into the LFT.

The specialized optical module is based on a spectral sensing technology. To use this spectral sensing chip AS7341L, a license and support from ams is necessary. For pricing and support, please contact us.

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
