Contamination of circuit boards can bring about severe degradation of insulation resistance and dielectric strength. Cleanliness of completed circuit boards is, therefore, of vital interest. For those companies who have established circuit board cleaning procedures, the MIL Spec P-a has been used as a guideline for control. Now a simple “on line” test for the relative measurement of ionic contamination has been ...

An important property of an optical component is the variation of the refractive index of the material from which it is made, broadly referred to as homogeneity. Material inhomogeneity causes variation of the refractive index in a glass, which can be in the form of sharp, cord-like regions called striae or it can occur as a gradient of the refractive index through a larger region of the sample. Material index variations must be qualified to ensure their impact is within tolerance for a particular optical design ...

Accurate qualification of optical components is a vital source of feedback to an optical manufacturing operation. From plano to spherical to aspheric shapes, common measurements include surface form error, waviness and roughness. Depending on the type of part and its application, material and geometric properties such as transmitted wavefront, homogeneity, wedge, parallelism, thickness variation, and radius of curvature may also require careful control. Optical components are the building blocks of optical ...

ZYGO laser interferometers are powerful and precise instruments for measurement and characterization of optical components and systems. One of the most common applications include the measurement of the radius of curvature. The radius of curvature is a fundamental and functional parameter of spherical optical surfaces, which requires quality control during ...

Our world is on the cusp of a stormwater design revolution - a change in the theories of stormwater management that we have held for 200 years which now call us to consider the impact of water quantity and quality on our future generations. Government agencies and their citizenry are calling for innovative new ways to ensure that our natural water resources remain vital and ...
