Overview

A black body is an idealized object that can absorb all external electromagnetic radiation without any reflection or transmission. In other words, a blackbody has an absorption coefficient of 1 and a transmission coefficient of 0 for electromagnetic waves of any wavelength. Physicists use this as a standard object for studying thermal radiation. It can completely absorb all external electromagnetic radiation without any reflection or transmission, and this object is called an absolute blackbody, abbreviated as a blackbody. According to radiation theory, any object that is not at absolute zero (-273.15 ℃) will have thermal radiation at any other temperature. The monochromatic radiation emissivity of a blackbody in thermal equilibrium in the hemisphere direction is a function of wavelength and temperature. At a certain wavelength, the monochromatic radiation emissivity of a blackbody is a single value function of temperature, and the temperature of a blackbody can be obtained by measuring the monochromatic radiation emissivity at a certain wavelength. This is the theoretical basis of radiation thermometry, the Planck radiation law of blackbody radiation. Blackbody radiation sources mainly measure the temperature of an object through the infrared energy emitted by the object, which is generally divided into high temperature, medium temperature, low temperature, etc. They are commonly used in the industrial and medical industries, mainly for calibrating radiation measuring instruments such as infrared radiation thermometers to improve

Product Details

Surface source blackbody - ISDC blackbody radiation source - standard surface source blackbody furnace - IR-160/301 is a flat panel emitter with a special high emissivity coating, with an average emissivity of 0.96. For applications where the cavity blackbody is too small to meet the requirements, the IR-160/301 surface source blackbody provides a large-area radiation source with high radiation intensity. The system includes an IR-160 surface source blackbody and an IR-301 temperature controller. The temperature range of the IR-160/301 standard surface source blackbody furnace covers room temperature to 350 ℃. Due to its large emission surface and the design structure of the surface source, it does not reach high temperatures like cavity source blackbodies. Surface source blackbody is mainly used to measure the uniformity, sensitivity, variable temperature difference, detectable temperature difference MRTD and other parameter performance of thermal imagers or infrared cameras. Therefore, the performance of surface source blackbody is mainly measured by indicators such as emissivity, uniformity, stability, accuracy, emissivity, resolution, etc. The standard surface source emission surface is generally rectangular in shape, and to improve emissivity, the blackbody surface has a convex peak structure. The standard surface source blackbody furnace is a standard equipment for infrared radiation detection, widely used in the technical index testing of process testing and identification testing in the development process of infrared detectors. At the same time, the ISDC blackbody radiation source, as the core equipment of the infrared imaging calibration device, is used in conjunction with the infrared collimation optical system and infrared target to complete key technical indicator testing and performance evaluation of the infrared imaging system.

Infrared Systems Development Corporation (ISDC) was formed in 1997 with the acquisition of Graseby Infrared’s instrument product lines, which were acquired from Infrared Industries (IRI), Infrared Systems (IRS), and Barnes Engineering Company. These products include blackbody sources, spectral radiometer systems, energy modulators and accessories.

The engineering, manufacturing and technical personnel involved with these products since their inception are included in the complement of our personnel.

We have modified and improved many of these products and have developed several new products, such as our infrared detector preamplifiers, and TE Cooled blackbody.

All of our products are developed and manufactured at our facility in Orlando Florida.

We also develop systems for custom applications, and offer design consulting services for many infrared instrument and sub-system projects. Our experienced staff can offer assistance in almost any IR field, and offer suggestions for your system needs. Contact us for more information.

MRTD is a comprehensive description of the spatial and temperature resolution of an infrared imaging system when imaging in noise. Simply put, as long as the NETD and MRTD values can be made smaller, the thermal imaging system is more sensitive to temperature differences. In actual imaging, even if two or more objects are close together and the temperature difference between them is small, thermal imaging can clearly distinguish them on the displayed image and provide feedback on the real scene. This is the "high imaging effect" of infrared thermal imaging. Conversely, the higher the value, the worse the imaging effect, and even the naked eye may only see a "dark lump" in the image. In fact, the expression of MRTD is very complex, mainly determined by NETD, optical system MTF, circuit MTF, circuit signal-to-noise ratio, D *, etc. The minimum distinguishable temperature difference reflects both the temperature sensitivity and spatial resolution of the thermal imager, as well as subjective factors of the observer, and is a comprehensive performance indicator of a system.
