New blueDrive Photothermal Excitation for Asylum Research Cypher AFMs uses a modulated blue laser to directly drive the cantilever during AC mode imaging, producing an ideal frequency and phase response.
AC modes typically rely on piezoacoustic drive, which in liquid produces an obviously distorted and time-varying response. In air, the high Q of the lever can mask the problem, but it still interferes with quantitative analysis.

Hitachi High-Technologies has announced the availability of the TM3030, the third generation of its series of tabletop scanning electron microscopes.
The TM3030 provides higher-resolution images and higher magnification capabilities through optimization of the electron optics system. The better resolution is especially useful for the 5kV mode of operation. Imaging at 5 kV reveals more surface detail and can be used for both topographic and elemental composition imaging.

Witec has announced the availability of its TrueSurface microscopy as an integrated option for the alpha300 microscope series.
This development enables topographic Raman Imaging on large samples for the full range of Witec instruments. The imaging mode is also available as an upgrade for installed alpha300 and alpha500 systems.

Confocal Raman imaging opened the door for many applications in Raman spectroscopy and imaging that were previously unavailable for measurement with conventional (non-confocal) Raman methods. However, high confocality always results in high focus sensitivity and this can make measurements difficult with rough and/or inclined samples. Especially when performing scans on a larger scale (scan size larger than 1 mm), this often necessitated careful alignment and extensive sample preparation.
