5 Optics

The pyrometers are equipped ex works with one of the following optics. These lenses are focusing

to certain distances, i.e. in these distances each lens achieves its smallest spot size in relation to

the measuring distance. The spot size will change in any other distance (shorter or longer). Please

notice that the measuring object must be as least as big as the spot size.

The name of the optics (e.g. optics 300) shows the measuring distance in mm (e.g. 300 mm) in

which it has the smallest spot size in relation to its measuring distance (IN 300, e.g. 20 mm).

The following drawings show the size of the spots in mm in dependence of the measuring dis-

tance. Values between the mentioned data can be calculated by interpolation. The spot size for

measuring distance 0 is the aperture diameter of the optics.
