Introduction

The term "near infrared" refers to a portion of the electromagnetic spectrum that lies between visible light and microwaves. This region of the spectrum is characterized by wavelengths ranging from 700 to 2500 nanometers. Near infrared radiation has gained significant attention in various industries due to its unique properties and applications. This article aims to provide an overview of the near infrared industry, covering its history, technological advancements, applications, and future prospects.

History of Near Infrared Technology

The concept of near infrared radiation dates back to the early 19th century when scientists began to study the properties of light. In 1802, William Hyde Wollaston discovered the infrared region of the spectrum, which is now known as the near infrared region. However, it was not until the late 20th century that near infrared technology began to gain prominence. One of the earliest applications of near infrared technology was in the field of spectroscopy. In the 1960s, scientists developed Fourier Transform Infrared (FTIR) spectroscopy, which enabled the analysis of chemical substances based on their near infrared absorption spectra. This breakthrough paved the way for the widespread use of near infrared technology in various industries.
