Thin pellicle beamsplitters

Thin pellicle beamsplitters offer low absorption, distortion, chromatic aberration, ghosting, and astigmatism. The nitrocellulose pellicle is ground to a 2-µm thickness and bonded to the face of a precision-lapped hard-anodized aluminum frame. Standard uncoated pellicles offer 90% transmission and 10% reflection through the visible and near-IR wavelength regions. Other transmission/reflection ratios can be achieved using specially coated pellicles.

Tracks of heavy ions 'imprinted' in lithium fluoride crystals. At the top, spot tracks observed under a fluorescence microscope in plates perpendicular to the heavy ion beam. At the bottom, the ion tracks in the parallel oriented plate (the blurring at both ends of the trace is an artifact of the depth of focus of the microscope). False colors.
