optical probe

An optical probe is a device equipped with optical components such as lenses, fibers, or detectors, designed to transmit and receive light for the purpose of measuring or analyzing optical properties of materials, surfaces, or biological samples.

Key aspects of optical probes include:

Light collection: Optical probes are designed to gather light from a defined area or point within a sample or system.

Transmission: They transmit collected light to external instrumentation or detectors for analysis or measurement.

Applications: Used in various fields such as biomedical imaging, spectroscopy, optical coherence tomography (OCT), and remote sensing, where non-destructive optical measurements are crucial.

Optical probes come in different configurations depending on the application, ranging from simple fiber-optic probes for light delivery and collection to complex imaging probes for detailed surface or subsurface analysis. They play a critical role in enabling non-invasive and precise optical measurements across diverse scientific and industrial disciplines.
