The list of available measured parameters includes: temporal noise, fi xed pattern noise, 3D-noise, responsivity, detectivity, dynamic range and linearity of the signal, quantum effi ciency, NETD, bad pixel location, non-uniformity correction, MTF, pixel surface response . The list of available measured parameters includes: temporal noise, fi xed pattern noise, 3D-noise, responsivity, detectivity, dynamic range and linearity of the signal, quantum effi ciency, NETD, bad pixel location, non-uniformity correction, MTF, pixel surface response . Consider measurement range, resolution, and environmental conditions. Our technical specialists can guide you through the selection process based on your specific needs. Each spectrometer undergoes. A spectrophotometer, as an analytical tool is used in almost every type of chemical, biological or life science laboratory. The instrument may range in complexity from a simple single beam instrument, right through to dual beam or complex and sometimes highly automated instruments. For calibration purposes, intrinsic atomic transitions like the line spectra of Hg, Ar, Ne, etc. In this technical note, we describe some fundamental characteristics of Fourier transform spectrometers that affect spectral. Spectral-domain optical coherence tomography (SD-OCT) has been established as a diagnostic imaging tool over the past few decades due to its advantages of high sensitivity and speed [1{7]. With the advent of broadband light source technologies, studies have pushed the axial resolution to 1-2 m [5.
