面议IR140面源黑体-ISDC精密中温面源黑体-ISDC精密黑体辐射源 产品描述:
IR140面源黑体-ISDC精密中温面源黑体-ISDC精密黑体辐射源 IR-140/301 是一种带有特殊高发射率涂层的平板型发射器,平均发射率为0.96。对于那些由于腔式黑体太小而无法满足的应用,IR-140/301面源黑体为其提供了具有高辐射强度的大面积辐射源。该系统包括一个IR-140辐射源和一个IR-301温度控制器,IR-140/301 标准面源黑体的温度范围覆盖:室温~230℃,因为其发射面大和面源的设计结构,它不像腔源黑体那样达到很高的温度。面源黑体主要用于衡量热像仪或红外相机的均匀性、灵敏度、可变温差、可探测温差MRTD等参数性能,所以衡量面源黑体的性能主要从发射率、均匀性、稳定性、精度、发射率、分辨率等指标。标准的面源发射面一般呈矩形状,为提高发射率,黑体表面是凸起的峰状结构。
标准面源黑体是红外辐射检测的标准设备,广泛应用在红外探测器研制过程中的工艺测试和鉴定试验的技术指标测试中。同时,面源黑体辐射源作为红外成像校准装置的核心设备,配合红外准直光学系统和红外靶标,完成红外成像系统等关键技术指标测试和性能评估。
Our extended area sources are flat plate emitters with special high emissivity coating providing 0.96 average emissivity. Extended area sources provide large target with high radiant intensity for application where a cavity blackbody is too small. The IR-140/301 System is covered by a one-year warranty.
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.
工作原理:
黑体(Black body),是一个理想化的物体,它能够吸收外来的全部电磁辐射,并且不会有任何的反射与透射。换句话说,黑体对于任何波长的电磁波的吸收系数为1,透射系数为0。物理学家以此作为热辐射研究的标准物体。它能够吸收外来的全部电磁辐射,并且不会有任何的反射与透射,这种物体就是黑体,简称黑体。根据辐射理论,任何物体只要不处于零度(-273.15 ℃),那么在其他任意温度下都存在热辐射。处于热平衡状态的黑体在半球方向的单色辐射出射度是波长和温度的函数。在一定的波长下,黑体的单色辐射出射度是温度的单值函数,可以通过某一波长下的单色辐射出射度的测量来得出黑体的温度。这就是辐射测温学的理论基础,黑体辐射的普朗克辐射定律。
黑体辐射源主要是通过物体所发出的红外能量来测量该物体的温度,一般分为高温,中温和低温等,常应用于工业和医疗行业中,主要是用于对红外辐射温度计等等一些辐射测量仪器进行校准,以提高测量仪器测量结果的准确性。黑体辐射源主要是使用红外辐射温度计或者其他一些辐射黑体测量仪器与黑体腔的温度进行测试、比较,从而实现对红外辐射温度计等一些其它的测量仪器进行校准。
