This McPherson spectrophotometer will help develop and test optical materials and coatings for high altitude and extraterrestrial (space flight) science missions.
A new ultraviolet spectrophotometer system for optical coating metrology just arrived at NASA Goddard (Greenbelt, Maryland USA). McPherson (Chelmsford, Massachusetts US) designed the system for optimal performance in the 90 to 160-nanometer wavelength range, also known as the deep or vacuum ultraviolet region. It was specially built with a windowless hydrogen plasma light source and differential pumping. This opens the spectrophotometer instrument up to many wavelengths beyond those of conventional UV deuterium lamps.
The new spectrophotometer system, called VUVAS-10X, uses a one-meter focal length high-resolution monochromator with special light source, scintillated detector and goniometric sample chamber.
McPherson will commission the system at NASA Goddard. Optical transmission, absorbance and specular reflectance are easily tested with angles of incidence up to 60 degrees. This McPherson spectrophotometer system helps develop, test and qualify optical materials and coatings for high altitude and extraterrestrial or space flight missions.
