Experiment set OPTICS 2

Precise measurements

The OPTICS 2 experiment set includes equipment for image and shadow forming. The frames for the lenses and the concave mirror have the principal planes for the lenses or the tangent to the centre point of the mirror marked on them with dotted lines. This makes it possible to determine object and image distances to a precision of half a millimetre, a highly precise way of measuring.

The universal track is also used as an optical bench

The same profiled rail used as a track, a stand, an inclined plane and a sliding surface for friction experiments in the MECHANICS sets is used here as an optical bench. The start of the scale is about 15 cm in from the end of the rail so that that object to be imaged (slide) can be positioned directly over the zero mark. This makes for extra-easy measurement of object and image distances. The universal track is not included in the set.

Enormous savings in time

Savings in time needed for conducting experiments constitute another advantage of this set. If the experiment lamp from the OPTICS 1 set is attached to the standardised stand rod, then it is immediately adjusted to the correct height as soon as it is snapped into place. Lens holders and screens are simply plugged into the corresponding riders, which can easily slide up and down the track and then be fixed in place.
