Large optical bench Overview A lightweight, removable optical bench designed for teaching and laboratory experiments in geometric optics. The guide rails include a scale for precise positioning, and the bench supports experiments on lens imaging, focal length determination, and basic light behavior such as refraction, reflection, convergence, and divergence. Key benefits Precise measurement: Scaled guide rails allow accurate placement of lenses, screens, and light sources for repeatable experiments. Portable and removable: At 1.8 KG and a compact footprint, the bench is easy to move and store while remaining stable during experiments. Complete accessory set: Includes essential optics components to run a range of lens and mirror experiments without additional purchases. Educational design: Clear manual with pre and post experiment questions encourages critical thinking and reinforces learning. What is included Large optical bench x1 Light source x1 White screen x1 1 word screen x1 Plastic frosted glass screen x1 Planoconvex lens x1 Double concave lens x1 Double convex lens x2 Candle holder x1 Brightly plated metal rod x1 Specifications Product type: Optical experiment bench Main use: Convex and concave lens imaging methods and focal length determination Structure: Removable Weight: 1.8 KG Size: 12 x 96 cm Function and compatibility Designed for experiments that demonstrate the straightline propagation of light, refraction, reflection, convergence, and divergence. Compatible with standard small optics accessories included in the set; modular layout supports additional lenses or screens if required. Guide rails with scale simplify measurement of object and image distances for focal length calculations and imaging demonstrations. Performance and materials Stable metal rod with bright plating provides a durable support for mounted components. Plastic frosted glass screen offers diffuse imaging and observation options alongside the white and 1 word screens. Lightweight construction balances portability with the precision needed for instructional use. Typical applications School physics class: Demonstrate image formation by convex and concave lenses and measure focal lengths with direct, handson experiments. Laboratory exercises: Perform systematic focal length determination and study image position and magnification using the scaled rail. Independent study or teacher demonstrations: Explore light paths, refraction, and convergence using multiple screens and lens combinations.
