Optical Spectroscopy & Spectral Analysis Architecture
Explore the fundamental physics of electromagnetic radiation, dispersive optics, high-resolution sensor arrays, and computational intelligence that together reveal material identity.
What Is a Spectrum?
A spectrum is a representation of how light or other electromagnetic energy is distributed across different wavelengths.
When light interacts with a material, some wavelengths may be absorbed, transmitted, reflected, or emitted differently. Measuring these interactions creates spectral information that can help scientists and engineers study the material.
Absorption
Light energy is captured and absorbed by molecules within the material, decreasing transmitted intensity at specific wavelengths.
Transmission
Light passes straight through the medium without being captured or scattered, revealing the optical transparency profile.
Reflection
Electromagnetic waves bounce off the material surface boundary, characterizing surface gloss, composition, and refractive index.
Emission
Excited atoms or molecules release photons as they return to a lower energy state, providing characteristic spectral peaks.
A World Beyond Visible Light
Human vision detects only a narrow window of electromagnetic radiation. By measuring ultraviolet and infrared wavelengths beyond human perception, spectroscopy unlocks non-destructive material insight and atomic-level precision.
