Abstract: According to an aspect, a UV radiometer is provided. The UV radiometer includes a sensor assembly and a sensor controller. The sensor assembly includes a UV sensor element and a temperature sensing component configured to perform a thermal adjustment of a sensed UV input from the UV sensor element to produce a compensated UV signal. The sensor controller includes a signal conditioning circuit configured to receive the compensated UV signal from the sensor assembly and produce a conditioned and compensated UV signal. The sensor controller also includes a communication interface configured to transmit the conditioned and compensated UV signal to a UV process controller.

Abstract: Certain embodiments described herein are directed to devices that can be used to align the components of a source assembly in a source housing. In some examples, a terminal lens configured to couple to the housing through respective alignment features can be used to retain the source components in a source housing to provide a source assembly.

Abstract: A baffle comprising a plurality of apertures wherein at least one of the plurality of apertures comprises a convergent portion and a divergent portion is provided. In some examples, a baffle comprising at least two concentric cones may be used. In other examples, the baffle may be used in an oil diffusion pump for use in an analytical device, such as a mass spectrometer.

Abstract: The cover for a fixed angle centrifuge rotor has an array of container support surfaces depending from the lower surface thereof. Each support surface is substantially cylindrical in configuration and has an axis associated therewith. Each container support surface is associated with a respective one of the cavities formed in the rotor body. In the most general case, when the rotor cover is attached to the rotor body, the axis of each container support surface lies in the same common radial plane as do the axis of the cavity with which the support surface is associated and the axis of rotation. In the common radial plane, the axis of a support surface is inclined at a predetermined angle with respect to the axis of rotation. The axis of the support may further be arranged to lie in parallel relationship to the axis of the cavity with which it is associated, or may define a predetermined angle with respect thereto.

Abstract: The present invention is directed to a centrifuge rotor having a rotor body and an associated lid. A skirt with a radially outwardly facing surface thereon depends from the radially outer peripheral undersurface of the lid. A contoured cut-out is formed in at least the radially outwardly facing surface of the skirt. The undersurface of the lid radially outwardly of the skirt also has a generally contoured cut-out formed therein. The contours of the cut-out portions meld together and cooperate to define a smoothly curved concave undercut region below the periphery of the lid that accepts a lifting implement, whereby lifting or lowering of the rotor may be facilitated.
