Biological & Food

Optical spectroscopy is increasingly used for both academic and commercial purposes in the study of biology, including tissue and disease characterization, cellular micro-analysis, food inspection, and microbe identification, among others. For food, it has been applied to measure moisture, fat, … More »


Forensic science is the application of science to criminal and civil laws as well as industrial accidents, as governed by the legal standards of admissible evidence and criminal procedure. Forensic scientists collect, preserve, and analyze scientific evidence during the course … More »


Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic spectrum. The goal of hyperspectral imaging is to obtain a spectrum for each pixel in an image of a scene, with the purpose of finding objects, … More »


In Chemistry, Agriculture and Geology near infrared measurements (700-2500 nm) are usually made in transmission and reflection and are used to probe the molecular structure and composition of materials. Near infrared is preferred over mid-infrared when measurements need to be … More »


Peptide identification and sequencing strategies by mass spectrometry have been very well-developed during the last 25 years after the soft ionization techniques have been introduced. When sequencing peptides with tandem mass spectrometry (MSn), peptides are cleaved at various locations off … More »


Near-infrared (NIR) light sources penetrate samples deeper and greatly reduce noise from fluorescence and other background lights, as compared to visible light sources. Both Raman and NIR spectroscopy are nondestructive optical analytical techniques. NIR spectroscopy is based on absorptions or … More »

Remote Sensing

Remote sensing has a wide range of applications in many different fields, including ground survey and monitoring, precision agriculture, terrestrial characterizing, hazard assessment, natural resource management etc. BaySpec’s OCI™-UAV hyperspectral imagers are ultra-compact, easily deployable, high-performance hyperspectral cameras designed specifically … More »


Raman spectroscopy has proven to be one of the most effective tools for characterization of semiconductor properties and for manufacturing process/quality control because materials such as Si, SiGe, InGaAs, GaAs, GaN, and graphene exhibit precise, distinct Raman bands.  Applied in … More »

Surface-Enhanced Raman

Surface-enhanced Raman spectroscopy (SERS) utilizes specialized metal substrates to allow Raman signal enhancement up to 10 orders of magnitude. This phenomenon occurs when the molecules of interest are in very close proximity to the metal substrate, and is generally used … More »


The modern expansion of computer and telecommunications has created a dramatic increase in the volume of worldwide data traffic that places increasing demands on communication network bandwidth. To meet this demand, fiber optic networks and dense wavelength-division-multiplexing (DWDM) communications systems … More »
