About This Product
The holder is placed on a stable bench or optical bench and the lens is inserted gently into its slot or clamp. Students align the lens with the light source, ray box, screen or object and adjust its position until the image, focal point or ray path is clear, then record their distance readings. It also serves as a replacement accessory in school optics setups.
