Surface Plasmon Resonance Apparatus

The Surface Plasmon Resonance Apparatus is designed to demonstrate the principles of Surface Plasmon Resonance and its applications in surface analysis. The apparatus enables the excitation of resonant electron oscillations using a polarized laser beam under specific conditions, allowing students to study optical sensing techniques used in modern scientific research. It provides an effective platform for understanding SPR-based detection methods widely used in chemistry, biology, material science, and nanotechnology. Manufactured by Atico Export India.

Principle

Surface Plasmon Resonance (SPR) is an optical phenomenon that occurs when polarized light strikes a thin metal surface under specific conditions, causing resonant oscillations of free electrons at the metal interface. The resonance condition is highly sensitive to changes occurring at the surface, making SPR a powerful technique for studying molecular interactions, thin films, and surface phenomena without direct contact.
