At the moment there exist several standards for testing of such instrumentation by trigonometric methods implementing several static point of collimation [2].
Procedures--Sets of radiographs were prospectively collected and evaluated for proper performance of various radiographic technical variables including exposure, collimation, positioning, inclusion of all appropriate views, presence of artifacts, radiation safety, and labeling.
The topics include applications of propagation invariant light fields, linearly traveling and accelerating localized wave solutions to the Schrodinger and Schrodinger-like equations, low-cost two-dimensional collimation of real-time pulsed ultrasonic beams by X-wave-based high-voltage driving of annular arrays, generating localized beams and localized pulses using the angular spectrum, and controlling the longitudinal and transverse shape of optical non-diffracting waves in the experimental generation of frozen waves in optics.
SANS instruments contain four major steps: monochromation using velocity selectors, collimation using source and sample apertures, scattering from samples with nanometer size structures and detection using position-sensitive area detectors.

laboratory-based, fixed horizontal beams, primitive collimation and blocking).
Previous researchers have used a compound parabolic concentrator (CPC) for this purpose, yet it takes a very large CPC to achieve the high degree of collimation needed.
Aside from obvious factors such as construction (polycarbonate, magnesium alloy or aluminum), foolproof waterproof sealing, protective armoring, lifetime warranties and overall collimation (how well internal parts work together), the gaseous elements occupying binocular interiors--nitrogen or argon purging in industry speak--determine how well glasses resist internal fogging when subjected to harsh elements or sudden temperature changes.
