Medical Diagnostics

850nm infrared light has also found its way into the medical field, where it is used for various diagnostic purposes. The non-invasive nature of this light makes it ideal for imaging and detecting abnormalities in tissues and organs. For instance, 850nm infrared light can be used in optical coherence tomography (OCT) to visualize the internal structures of the eye, such as the retina and cornea. This technology is crucial for early detection and treatment of eye diseases. Moreover, 850nm infrared light is employed in thermography, a technique that detects heat variations on the surface of objects. This application is particularly useful in diagnosing conditions such as breast cancer, where subtle temperature changes can indicate the presence of tumors. The non-ionizing nature of 850nm light makes it a safe and effective tool for medical diagnostics.

Industrial Applications

The industrial sector also benefits from the use of 850nm infrared light. This wavelength is utilized in various processes, including material inspection, quality control, and manufacturing. For example, 850nm infrared light can be used to inspect the integrity of materials, such as detecting cracks or defects in metal components. This helps in ensuring the safety and reliability of products. In addition, 850nm infrared light is used in thermal processing, where it can be employed to control the temperature of materials during manufacturing. This is particularly important in the production of semiconductors, where precise temperature control is essential for achieving high-quality products.
