Hemispherical Reflectance and Emittance Properties of Carbon Nanotubes Coatings at Infrared Wavelengths

Description: In this NASA – Goddard paper the hemispherical reflectance and emmitance properties at IR wavelengths of experimental nano-tube coatings are compared with Acktar Fractal Black. A Fractal Black coated disc is used as a “black standard” in the measurements Hemispherical Reflectance and Emittance Properties of Carbon Nanotubes Manuel A. Quijada, John G. Hagopian, Stephanie Getty,…

What Exactly Is Black Oxide Coating And What Does It Do?

Black oxide coating is the process of coating ferrous materials, stainless steel, copper, copper based alloys, zinc, materials with a chemical coating process. It takes products, and it coats them in iron oxide. This provides many benefits. First, it reduces light reflection. This is beneficial because for products such as IR sensors, UV sensors, passive infrared…

Deepest Black Absorber-Layers for Safe Satellite Navigation

Similarly to how sailors have done for thousands of years, the navigation sensors of satellites now operate in space. With ultra-black layers, which reliably absorb scattered light, these ‘navigation systems’ can be built very light and reliable. For thousands of years, seafarers relied on the stars and determined their location by means of sextants. The sextants…

What are light modifiers and how to use them?

As we all know, correct lighting crucial to a professional looking photograph. It’s also in the literal meaning of the term photography – “drawing with light”. So, to transform light into art, it’s important to learn about the tools. At a basic level, we can use the sun, a continuous source, or a flash. If we’re…

Infrared Spectroscopy (IRS) – A Molecular Overview

What is infrared spectroscopy? infrared spectroscopy (also known as IR spectroscopy, vibrational spectroscopy, or [henceforth] – IRS) is the measurement of infrared radiation as it interacts with matter by absorption, emission, or reflection. Uses of IRS The most common uses of IRS are the studying and identifying of chemical substances or functional groups in solid, liquid,…

Aluminum coating – uses and advantages

As opposite to light absorbing coatings in many parts there are areas with highly reflective surface, like mirrors or semi mirrors. One of the popular reflective coatings is aluminum. Outside surface: aluminum coating, internal surface: Acktar Fractal BlackTM coating Aluminized coating is a surface treatment that can be applied to different base metals but is…

What Is Optical Coating?

A proper definition of an optical coating is one or more thin layers of material creates an effect and interaction between light and a certain optical component- such as a lens or mirror. To understand optical coatings, you have to know how light interacts with transparent media. The layers’ effect alters how the optic reflects and…

LWIR Sensors

Long-Wave Infra-Red (LWIR) refers to multi and hyperspectral data collected in the 8-15 µm wavelength range. LWIR surveys are sometimes referred to as "thermal imaging" and can be used to identify relatively warm features such as hot springs, fumaroles and snow melt. LWIR sensors can also be used to map the distribution of certain minerals related…
