Vacuum spectrometers from
McPherson (Chelmsford, MA) have a
670mm focal length. The spectrometers
feature stainless steel housings and components
for ultra-high-vacuum applications. The instruments readily achieve
10E-6 torr vacuum during operation with elastomer (Viton™ or Buna-N)
seals. The McPherson models have master polished optics, multiple entrance
and exit port locations, and high precision wavelength drives for wavelength
reproducibility. Specialized high reflectivity coatings provide up to 78% reflective
efficiency at wavelengths as short as 120 nm. The device has an f/4.7 aperture
ratio (670mm f.l.). The tools are available in focal lengths of 0.67, 1.0,
1.3, and 2-meters.
