Vacuum Ultraviolet Irradiation of Polymers
Plasmas and Polymers, 1999The interest in incoherent sources for wavelength-selective photochemistry has increased lately, but little is still known about the behavior of polymers when exposed to far UV and vacuum UV (VUV) radiation. The same dearth of information exists regarding UV (VUV) radiation emitted by low-pressure plasmas during polymer treatment. In order to study VUV-

OPTICAL ACTIVITY IN THE VACUUM ULTRAVIOLET
Annual Review of Biophysics and Bioengineering, 1976This review describes the recent development of vacuum ultraviolet circular dichroism (VUCD) spectrometers and the results that have been obtained with them. Optical activity is a property of material that can be displayed phenomenologi cally in either of two forms.

Japanese Journal of Applied Physics, 1985
A new vacuum ultraviolet detector has been fabricated. A sample was made using a crystalline quartz plate on the surface of which a metal electrode was deposited. It has been experimentally established that the sample is sensitive to VUV radiation, and the external quantum efficiency is estimated to be higher than several percent.

Vacuum Ultraviolet Scattering Distributions
Applied Optics, 1968Measurements of reflectance and the profile of scattered intensity from rough and smooth surfaces are reported for incident radiation of 1216 A The profiles show the intensity of scattered uv in the plane of incidence at various incident angles. Black appearing surfaces are found to have reflectances higher than expected.

Vacuum Ultraviolet Spectrometer
Review of Scientific Instruments, 1963A grazing incidence vacuum spectrometer is described. It is based on a 2-m, 30 000-lines/in., Siegbahn glass grating. Both plate holder and grating are held on arms fastened to the axis of the Rowland circle. The wavelength range extends up to 2300 Å. Instrumental considerations for obtaining high resolution in the short wavelength range are discussed.

Generation of Ultraviolet and Vacuum Ultraviolet Radiation
1974The paper describes the use of nonlinear optical techniques for the generation of coherent radiation at ultraviolet, vacuum ultraviolet, and soft x-ray wavelengths. Mixtures of metal vapors and inert gases, and other mixed gas systems, allow generation to regions of the spectrum where nonlinear optical crystals are opaque; and also allow generation at ...

Reflectometer for the Vacuum Ultraviolet*
Journal of the Optical Society of America, 1960A newly designed device for the measurement of absolute reflectance in the vacuum ultraviolet region is discussed. Notable features of this reflectometer are compactness and simplicity. The source and monochromator with which the reflectometer is used are also discussed.

Vacuum Ultraviolet Monochromator
Review of Scientific Instruments, 1962A new focusing vacuum monochromator is described which incorporates features making available a simple and flexible double monochromator with a single control. The focusing is provided with a linear motion coupled to a nearly balanced linkage system which, coupled to the grating, satisfies the conditions of the Rowland mount.

Physics Bulletin, 1973
The first vacuum ultraviolet laser, operating at around 160 nm in the Lyman band of molecular hydrogen, was developed in 1970 simultaneously at the Naval Research Laboratories (Waynant et al 1970) and IBM (Hodgson 1970). Since then there have been rapid developments in both molecular and quasimolecular lasers operating at wavelengths as short as 110 nm.
