把军事和空间应用领域从事的研究红外辐射度的工作,扩大到其他诸如要了解玻璃,塑料、油料、火焰及其他物质的热性能的应用领域,已经成为日益迫切的要求了。其他物质是指红外特性会因厚度、组分和波长不同而发生变化的物质。令人遗憾的是,在工业部门和院校工作的、富有潜力的研究人员,不像他们在军事和空间研究部门的同行有那么多的研究资金。因此,他们需要这样一种专为红外研究设计的多波段光谱仪,这种光谱仪不但性能稳定、经过绝对校准和功能多到足够完成上述测量任务,而且价格不高,是工业部门和院校研究人员能够购置的。本文将概述12—880型精密滤光片辐射计的发展过程,该辐射计是在对一种标准专用红外测温计加以改进结构和扩充功能的基础上发展成的。这种专用红外测温仪独特的、高度稳定的热学/光学结构使得这一发展成为可能。本文还将叙述新仪器的一些已经证实了的用途以及可能具有的用途。
It has become increasingly urgent to extend the work on infrared radiance conducted in military and space applications to other applications such as understanding the thermal properties of glass, plastics, fuel, flame and other substances. Other substances refers to the infrared characteristics of the thickness, composition and wavelength of the material changes. Unfortunately, promising researchers working in industry and academia do not have as much research funding as their counterparts in the military and space research sectors. Therefore, they need such a multi-band spectrometer designed specifically for infrared research. This spectrometer not only has stable performance, but also has enough absolute calibration and functions to accomplish the above measurement tasks at a relatively low price. It is not only used by industrial and academic researchers Can be purchased. This article will outline the development of the 12-880 Precision Filter Radiometer, developed on the basis of improved structure and expansion capabilities of a standard dedicated infrared thermometer. The unique, highly stable thermal / optical structure of this dedicated infrared thermometer makes this development possible. This article will also describe some of the proven uses of the new instrument and possible uses.
