Used OXFORD 7421 #9200384 for sale

OXFORD 7421 spectrometer is an advanced spectrometer manufactured by OXFORD Instruments Company. It is a general-purpose multi-channel spectrometer designed to measure a variety of physical parameters including optical absorbance, transmission, and reflectance. It is composed of three main components - the Optical Spectrometer, the Detector Assembly, and the Control Electronics. The Optical Spectrometer consists of an optical monochromator, a light source, and an illumination fiber. The monochromator is used to select a single wavelength of light which is then transmitted through the sample via the illumination fiber and measured by the detector. The detector is an energy-sensitive silicon photodiode which produces an electrical signal proportional to the sample's light intensity. The control electronics regulate the current and voltage to the detector and process the measured signal. 7421 spectrometer has a maximum optical spectral range from 190nm to 1100nm with an adjustable bandpass of 0.5-1.5nm. It is equipped with a self-calibrating digital lock-in amplifier to detect signals with a high signal-to-noise ratio. Furthermore, it is also capable of performing scans of thousands of detector points between two wavelengths per second. Additionally, it is compatible with a variety of different software applications which can be used to analyze the data collected. OXFORD 7421 spectrometer is suitable for a variety of applications, including chemical analyses, biochemical and forensic spectrometry, quality control of industrial materials, and medical diagnostics. It is designed to withstand high vibration, shock, dust, and humidity levels and features a long life. 7421 spectrometer is an ideal choice for researchers seeking a reliable and efficient spectrometer.
