These systems are modular – the spectrograph has interchangeable gratings and slits, allowing you to choose the required resolution over your spectral range of interest. It is ideal for researchers with changing needs. For less demanding applications, we offer the more economical OSM Series InGaAs Spectrometers on page 1253. These systems include everything you need to begin your work: • MS125™ Spectrograph (see page 1209 for full details) • Your choice of grating • Your choice of entrance slit with input slit holder • 256 or 512 InGaAs Photodiode Array System • LineSpec™ Software MS125™ Spectrograph We tested our LineSpec InGaAs PDAs with various Oriel Spectrographs, and settled on the MS125 as the instrument of choice 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. Table 1 lists the grating choices and instrument specifications.

System efficiency will also be affected by the reflectivity of the spectrograph's mirrors and the grating angle, at any wavelength. 0.5 0.6 QUANTUM EFFICIENCY (ELECTRONS / PHOTONS) 0.7 0.8 0.9 1.0 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 0.25 0.50 0.75 1.00 0 WAVELENGTH (ìm) Fig. 1 Quantum efficiency of LineSpec InGaAs PDA. InGaAs Photodiode Array Detector Systems The detection system is made up of a TE cooled linear InGaAs photodiode array sensor and a single stage thermoelectric cooler. The detector head has a 12 bit USB interface; data transfer time to the computer is ~ 6 ms. We offer arrays with 256 and 512 pixels and array lengths of 12.8 and 25.6 mm, respectively. Pixel size is 500 ìm high by 50 ìm wide, on 50 ìm centers. LineSpec Software The LineSpec™ software is an intuitive instrument control and data acquisition software that runs under Windows 98/W2K/XP. The software supports routine spectroscopic measurements and data acquisition, such as: continuous, single and averaging scans; absorption, transmission and emission spectra; irradiance measurements. Data may be exported into most MS applications. • Complete Packages - 1/8 m Spectrograph and InGaAs PDA • 800 - 1700 nm spectral response • 256 and 512 pixel arrays • High sensitivity and high dynamic range • True plug and play systems - USB interface and dedicated LineSpec™ software • TE cooled to 5° C
