A D-shaped glass slab is a type of optical element with a unique shape. Here's a description:
"A D-shaped glass slab is a rectangular glass plate with one side curved like a semicircle, resembling the letter 'D'. It has five polished surfaces: the flat rectangular side, the curved side, and three edges. The flat side is typically the base, while the curved side is used for refraction and total internal reflection experiments. The D-shaped slab is used in optics to demonstrate refraction, reflection, and dispersion phenomena."
Dimensions:
- Length (flat side): 5-10 cm
- Width (flat side): 3-6 cm
- Height (curved side): 3-6 cm
- Radius of curvature (curved side): 5-10 cm
