McPherson's new vacuum spectrometers features stainless steel housings and components for ultra-high vacuum applications. The instruments can achieve 10E-6 T vacuum during operation with elastomer seals and feature master polished optics, multiple entrance and exit port locations and high precision wavelength drives. High reflectivity coatings provide up to 78% reflective efficiency at wavelengths as short as 120 nm and other coatings are available for performance in mid-wave and long-wave infrared applications. An f/4.7 aperture ratio enables good light throughput. Fitted for wavelength scanning and imaging applications, the spectrometers can accommodate many commercial back-thinned, windowless 2D CCD and CMOS sensors and many single channel silicon diode or scintillated photomultiplier-type sensors. The instruments are suitable for experiments involving transient or fast plasma physics, astrophysics, material science or laser-matter interaction experiments. They are available in focal lengths of 0.67 m, 1.0 m, 1.3 m and 2 m and can be prepared for high-vacuum and also ultra-high vacuum applications with all metal seals. Various vacuum compatible accessories are available.
