The CMOS detectors have a well capacity that is 24-30X greater than the linear CCDs, and so the signal to noise ratio of a CMOS detector ~4X greater than for CCD detectors. Overall, the CCD is 2.9 x 23.4 = 67.9X more sensitive than the CMOS detector. The CCD’s much larger gain makes it 23.4X more sensitive. Because the CCD pixels are 2.9X larger than the CMOS pixels, the CCD sees 2.9X more light. CMOS vs CCD Detectors The key differences between the CCD and CMOS detectors are sensitivity and dynamic range. 1 Quantum efficiency of CCD and CMOS Detectors.
System efficiency will also be affected by the reflectivity of the spectrograph's mirrors and the grating angle, at any wavelength. ** The primary wavelength region is where the grating efficiency is >20%. This item SOLD at 2011 Feb 11 10:40 UTC-7 : PDT/MST. SOLD 15.00 USD to floor + buyers premium + applicable fees & taxes. The MS125 is a micrometer driven, 1/8 m (120 mm), focal length instrument. MS125™ Spectrograph We chose the MS125 as the spectrograph for these systems, because of its high resolution and throughput, economical price, and compact size. We also offer the array detectors separately, for mounting to other Oriel Spectrographs. LineSpec Spectrometers are made up of our Oriel MS125TM 1/8 m spectrograph (fully detailed on page 1209) and an external 2048 CCD or 1024 CMOS array. Gratings and slits are interchangeable so you can re-define the usable spectral range and resolution, as your needs change.
