Gratings and slits are interchangeable so you can re-define the usable spectral range and resolution, as your needs change. 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. We also offer the array detectors separately, for mounting to other Oriel Spectrographs. MS125™ Spectrograph We chose the MS125 as the spectrograph for these systems, because of its high resolution and throughput, economical price, and compact size. The MS125 is a micrometer driven, 1/8 m (120 mm), focal length instrument.

System efficiency will also be affected by the reflectivity of the spectrograph's mirrors and the grating angle, at any wavelength. 70 60 50 40 QUANTUM EFFICIENCY (%) 30 20 10 WAVELENGTH (nm) 200 300 400 500 600 700 800 900 1000 CMOS CCD Fig. 1 Quantum efficiency of CCD and CMOS Detectors. CMOS vs CCD Detectors The key differences between the CCD and CMOS detectors are sensitivity and dynamic range. Because the CCD pixels are 2.9X larger than the CMOS pixels, the CCD sees 2.9X more light. The CCD’s much larger gain makes it 23.4X more sensitive. Overall, the CCD is 2.9 x 23.4 = 67.9X more sensitive than the CMOS detector. 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. In short, CMOS detectors have application for high signal, high dynamic range and high S/N measurements, whereas CCD detectors are for low signal measurements. • Complete packages - Oriel MS125TM Spectrograph and linear array detector • 1024 CMOS and 2048 CCD linear arrays • True plug and play systems with USB interface
