🔬 What is a Non-Dispersive Optical System?

A Non-Dispersive Optical System (NDOS) is an optical technology that minimizes light dispersion to selectively utilize specific wavelengths.

In conventional spectroscopy, prisms or gratings are used to disperse light into various wavelengths, but non-dispersive optical systems bypass this process, detecting or manipulating only selected wavelengths.

A representative example is the Non-Dispersive Infrared (NDIR) sensor, which measures gas concentrations by analyzing absorption spectra.

💡 Principles of Non-Dispersive Optical Systems

Non-dispersive optical systems operate by selectively transmitting or reflecting specific wavelengths of light using optical filters or laser technology.

The most crucial component in this process is the optical filter.

An optical filter allows only certain wavelengths to pass through, blocking unnecessary wavelengths to enhance signal accuracy.

Additionally, laser technology is used to directly emit specific wavelengths, playing a key role in non-dispersive optical systems.
