Klinger LED Laser Ray Box

This laser ray box uses cylindrical LED lenses to focus the beam.

The LED laser ray box consists of five independent laser modules producing five parallel lines that are collimated by LED cylindrical lenses to be extremely visible with pinpoint accuracy. It is taped with magnetized foil, allowing intuitive attachment to a magnetic board. The laser effectively demonstrates the transmission of rays through a combination of optical elements. Five clearly visible parallel LED line rays can be seen easily due to collimation by cylindrical lenses. Moreover, it increases the comfort of teaching geometric optics due to electronic shade control and green optical axis which highlighted and, therefore, stands out clearly.
