Product overview A clear, thin PET microscope accessory designed to provide precise reference marks and lines for imaging, alignment, and measurement tasks. Practical and easy to install, it works with standard stereo and compound microscopes that accept small transparent overlays. Key benefits Improves repeatability: Precise dot and line markings help position samples consistently and speed up routine imaging or inspection. Clear visibility: transparency PET maintains optical clarity while displaying accurate printed patterns. Fine resolution: Very small dot and line sizes support detailed work and close focus at higher magnifications. Simple to use: Thin, flexible sheets are easy to place, remove, and store without tools. Specifications Model: 90x55mm3 Size: 90 x 55 mm Material: transparent PET Sheet thickness: 0.1 mm Dot diameter range: 0.05 to 2.0 mm Line thickness range: 0.03 to 2.2 mm What makes this product stand out Wide range of dot and line dimensions covers tasks from coarse alignment to finescale reference marking. transparency PET preserves image quality while providing a durable surface for printed reference patterns. Thin 0.1 mm construction minimizes added optical path length and works with closefocus objectives. Typical applications Classroom microscopy and lab training: Use the overlay to demonstrate scale, teach sample positioning, or guide students through systematic observation. Imaging and calibration: Place the sheet under the objective to check focus, verify measurement scales, or align fields of view before capturing images. Inspection and assembly: Helpful for small parts inspection and positioning in electronics, watchmaking, or other precision assembly tasks that use a microscope or magnifier. Compatibility and handling Suitable for microscopes and magnifiers that can accommodate a 90 x 55 mm transparent sheet in the sample area or on the stage. Handle by the edges to keep the surface clean. Clean with a soft, lint cloth if . Store flat to avoid bending or creasing. Contents and packaging Refer to model 90x55mm3 for included quantity and format. This accessory provides a simple, reliable way to add reference marks to your microscopy workflow while maintaining optical clarity and fine resolution.
