The 74128 VIS-NIR Oriel Cornerstone 260 1/4 m Monochromator is an economical, fully automated, multi-grating instruments with dual output ports and exceptional optical performance. This UV-VIS version has USB 2.0 communications and includes the 74066, 74067, and 74069 gratings as well as (2) 74001 Micrometer Driven Slit Assemblies. Simply program your filter, grating, and port changeover points, and walk away while Cornerstone 260 automatically scans from the VIS through the NIR. Other standard features include a built-in electronic shutter, filter wheel control, and a family of interchangeable gratings and slits. The Cornerstone 260 uses an asymmetrical in-plane Czerny-Turner optical configuration. The input F/number is F/3.9. The resolution is 0.10 nm (dual grating instruments with a 1200 l/mm grating and 10 µm x 2 mm slit). Throughput is high and stray light is very low. We relied on our extensive research on optical flat black paints and baffles, and the use of high efficiency spherical mirrors and gratings to minimize surface reflections, and thus, stray light.
