Graticules, reticles, and grids are precision tools used in microscopy, optical instruments, and imaging systems to aid in measurement, alignment, and targeting. Commonly integrated into eyepieces or slide-mounted formats, they enhance accuracy during observations and support standardized data collection in research, metrology, and clinical diagnostics. With various patterns and calibrations available, these tools are adaptable to diverse analytical tasks, improving consistency and workflow efficiency across scientific and technical disciplines.
Pure Silicon TEM Windows, Electron Microscopy Sciences
Supplier: ELECTRON MICROSCOPY SCIENCE
Pure silicon TEM windows feature imaging windows with 5 to 35 nm thickness, reducing background contribution and interference for higher contrast imaging. Most impressively, 5 nm thick non-porous pure silicon TEM Windows are thinner than the thinnest commercially available amorphous carbon membranes.
