PATIKIL 30mm /1.2 Inch Triangular Prism, 2 Pack Glass Optical Crystal Rainbow Prism for Photography Physics Teaching Lights Photo, Clear

Features

• A triangular prism is a tool used to split white light into its spectral colors, showing the principle of distribute. It is suitable for use in physics experiments, teaching, photography, and more.
• Specification; Color: Transparent; Material: Glass; Length: 30mm/1.2 Inch; Side Width: 30mm / 1.18 inch; Packing List: 2 x Triangular Prism
• Advantage: 1.Made of quality optical glass for superior clarity and precision, it is durable and practical for use. Moreover, it is compact, and convenient for you to carry it outside photography. 2. Triangular shape design that reflects light, splits white light into colors and produces a beautiful rainbow effect.
• Instruction: Step1. Place the triangular prism on a flat surface with one of its faces down.
