Optical K9 BK7 Glass Cube for Precision Imaging and Display Compact, precise, and versatile optical element designed from K9 BK7 optical glass. Its measured size and sixsided geometry provide consistent results for visual applications where clarity and repeatable effects matter. Key benefits Opticalgrade material: K9 BK7 optical glass offers stable optical properties and clear light transmission for reliable visual performance. Compact and portable: 30 x 30 x 30 mm footprint and about 85 g weight make it easy to position, transport, and integrate into small setups. Sixsided design: six polished sides increase available viewing angles and interaction surfaces, supporting a wider range of image and light conversion scenarios. Consistent results: uniform dimensions and material help maintain repeatable outcomes across multiple shots or measurements. Easy to incorporate: simple geometry and compact size allow straightforward placement in photo, video, or tabletop setups. Function, compatibility, and performance Function: serves as an optical element for producing controlled refraction, reflection, and multiangle viewing effects in visual and educational settings. Compatibility: suitable for use with standard photography and videography rigs, small optical benches, desktop displays, and demonstration kits. Performance: precisioncut optical glass combined with the cube form factor supports predictable and consistent visual behavior in practical setups. Use scenarios Creative photography: add prism and reflection effects to product or portrait shots by positioning the cube between lens and subject to capture multiangle highlights and reflections. Educational demonstrations: illustrate refraction, internal reflection, and angledependent optical behavior in classroom or lab demonstrations. Product display and staging: use on a desktop or tabletop to create controlled reflections and add visual interest to product photos or retail displays. Specifications Material: K9 BK7 optical glass Size: 30 x 30 x 30 mm Weight: about 85 g Faces: six sides to improve conversion rates This optical cube provides a compact, reliable element for anyone needing precise, repeatable visual effects and multiangle viewing in smallscale optical and creative applications.
