High Efficiency Double Spot Beam Splitter

LASER COMPONENTS (Bedford, NH) has introduced the HEDS (High Efficiency Double Spot) beam splitter. Double spot beam splitters are diffractive optical elements (DOE) used for separating an incoming laser beam into two identical beams. They are most commonly used in lithography as well as high power applications such as cutting and perforation. Until now, a small portion of light was lost in higher diffraction orders. Some applications cannot tolerate even a 1% loss, so this DOE boasts an efficiency well above the standard value of 81%. HEDS is available in wavelengths between 193 nm and 10.6 µm.

Scanning Electron Microscope

JEOL USA (Peabody, MA) has introduced a new Scanning Electron Microscope (SEM) that combines the performance of a Field Emission SEM with the simplicity of the JEOL InTouchScope™ SEM series. The new JSM-IT300HR features a rugged in-chamber specimen stage and large chamber to accommodate a wide variety of samples of different shapes, sizes, and weights. The specimen chamber’s twelve geometrically-optimized analytical ports allow for multiple detectors, creating a virtual nano-lab inside the SEM. Low vacuum capability is a standard feature and allows for imaging and analysis of all types of samples in their native state.
