WebBased on the success of eXcelon technology, a new CCD enhancement process called eXcelon 4 has been developed specifically for NIR Raman applications, and more specifically in vivo Raman spectroscopy. eXcelon … WebSpectroscopic etaloning is related to, but different from, spatial etaloning. It derives from the fact that in a spectrometer the wavelength of light varies across the CCD. Thus, even …
WebDec 2, 2016 · Although the etaloning effect associated with BT-CCDs can be mitigated by a deep depletion process, this will again increase the cost of the production process. PDA detectors are more conventional linear … Webvariation is called the etaloning effect. Etaloning occurs when the laser strikes a component of the ... That pattern is the result of etaloning, and they are not real peaks in the spectrum. Figure 3 shows the same spectrum following relative intensity correction, where the pattern is removed and the spectrum looks a lot clearer. ...
WebJul 23, 2024 · Back-illuminated charged-coupled device (BI-CCD) arrays increase quantum efficiency but also amplify etaloning, a multiplicative, wavelength-dependent fixed … WebSpectroscopic Etaloning in Back Illuminated CCDs. Introduction ... The back surface is processed in a proprietary way that helps to break up the etalon effect. The combination of these approaches has resulted in a …
WebMinimising Fringing Effects at Higher Wavelengths. Another key consideration for some applications is to minimize “fringing” effects due to the window; this effect is directly related to the coherence of the light incident on the camera. Fringing effects can occur due to the etaloning effect within the window substrate.
WebOptical etaloning on any back-illuminated CCD can only be minimized, never completely removed ‘Fringe-suppression’ technology is an effective way to reduce etaloning effects in both back-thinned CCDs optimized … receiver idWebThe Most Sensitive Detector in the NIR with Minimized Etaloning Effects The Jobin Yvon Back Illuminated Deep Depletion 1024 x 256 CCD is the best choice for low light level applications in the NIR (500 nm –1000 nm) including Raman, Photoluminescence, and Fluorescence spectroscopy. university that accept international studentsWebA similar effect is seen in back-illuminated NIR detectors, where the detector substrate itself acts as an optical etalon.
