http://nernst.de/lamp/nernstlamp.htm WebThe attenuation coefficient ratio (αλ/α0.546) for artificial fogs has been measured at 345 μ. The attenuation coefficient ratios at 0.436 μ, 1.01 μ, 3.5 μ, 10 μ, and 13.5 μ were also measured so that a comparison between artificial fogs and natural fogs could be made. By comparing our results with others on natural fogs and with the theoretical work of others …

WebIR light through a sample is measured using a mercury-cadmium-telluride detector. The main sources of infrared radiation used in spectrophotometers are (1) a nichrome wire … WebInfrared sources consist of an inert solid that is electrically heated to a temperature between 1,500 and 2,200 K. The heated material will then emit infra red radiation. The Nernst … WebThe Nernst glower is a rod of ZrO 2 or Y 2O 3 that is 1-3 mm in diameter and 1 - 3 cm in length. It is heated to a temperature between 1200 - 2000 K and outputs a blackbody spectrum from 25,000 to 500 cm-1. A high pressure mercury lamp has a plasma emission as well as the characteristic atomic spectrum. The plasma emits in the far right stuf interspecies reviewers
