Stray Radiation in Optical Systems II.
Scatter measurements were performed on one sample each of ZnSe and ZnS (sometimes called 'cleartrans') in 5.0 degree intervals from 5.0 degrees to 180 degrees (an additional point, 3.7 degrees from specular was also obtained). Two detectors were avai

Many analyses are found to be simpler in direction cosine coordinates. The analyses occasionally concern data obtained at angles far from specular. In order to avoid design error, the magnitude of the difference between transformed value and measured

Scatter from Optical Components.
The analysis of scattering test results often raises questions of whether facility or sample anisotropy is responsible for variation in data. The sample may appear macro-scopically isotropic yet, as in the case of a Si wafer, may affect results due t

Intense, coherent, far infrared radiation from a line-focus plasma has been detected by a spark gap system. Filter experiments were used to determine the approximate wavelength.

A Q‐switched ruby laser was used to study the anti‐Stokes Raman radiation scattered at 180° in liquid carbon disulfide. Frequency‐doubled ruby light at 3473 A was used to excite amplifier cells containing either rhodamine B or rhodamine 6G. Se

The comparison of BRDF (Bi-directional Reflectance Distribution Function) measurements made on the same system but at different times or days is a method of determining potential sample or system change. If the measurements lie within the acceptable

An attempt was made to prove the identity of the set of equations describing the Raman phenomenon with the set describing four-wave mixing. The result is a classic proof by contradiction: for the two phenomena to be the same, 1 would have to equal 3/
