P050043 Optical bench
Thin lens imaging optical bench and the slider adopt the same cross-section of aluminum material, only with different length. The slider can slide and be locked in the optical bench. It's steady and easy to operate.
Optical bench: oxygenated for the silver-white color, length 1000mm, with graduation, accuracy degree 1mm.
Slider: black, length 40mm,printed with index lines, each 3.
Light source: AC 220V, 40W bulbs, installed in the length of 100mm aluminum materials with a juction box and switch.
Diameter:80mm, plastic frame, a convex lens with handle.(focal length 12cm)
The screen (white) 1 color
Object screen and aperture diagram, red and green light and the part of transmission have a center-to-center spacing 1mm vertical and horizontal line. The location of imaging can be accurately measured. With its magnetic properities it can be adsorbed on the aperture diagram(opening diameter 2cm)
