Infrared (IR) wavelengths are an essential part of the electromagnetic spectrum, often used in applications ranging from thermal imaging to industrial heating. The ability to control and manipulate infrared radiation is critical in various scientific and technological fields, and one material that has gained attention for its impressive IR absorption and low reflectivity properties is Metal Velvet.
In this blog, we will explore the nature of infrared wavelength, their practical applications, and how Metal Velvet plays a crucial role in infrared absorption and radiation management.What Are Infrared Wavelengths?
Infrared radiation lies just beyond the visible spectrum, with wavelengths ranging from 700 nanometers (nm) to 1 millimeter (mm). It is categorized into three main regions:
- Near-Infrared (NIR) (700 nm – 1.4 µm) – Commonly used in fiber optics, remote sensing, and night vision.
- Mid-Infrared (MIR) (1.4 µm – 3 µm) – Found in thermal imaging, spectroscopy, and some heating applications.
- Far-Infrared (FIR) (3 µm – 1 mm) – Primarily used in thermal radiation, deep-space astronomy, and industrial heating.
Infrared energy is closely related to heat transfer, as most objects emit IR radiation depending on their temperature. The ability to manipulate these wavelengths is crucial for applications like thermal insulation, aerospace technology, and stealth coatings.The Role of Metal Velvet in Infrared Absorption
One of the biggest challenges in infrared applications is controlling how materials absorb and reflect IR radiation. This is where Metal Velvet comes into play.What is Metal Velvet?
Metal Velvet is a highly specialized material known for its extreme light absorption properties, particularly in the infrared spectrum. It is made using microscopic metallic fibers arranged in a way that creates a deep, light-trapping surface. This structure enables Metal Velvet to absorb up to 99% of incident infrared light, making it an excellent material for applications requiring minimal reflectance and maximum heat absorption.Key Properties of Metal Velvet
