3.2 LED targeting light

The pyrometers are equipped with an LED targeting light for aiming onto the measuring object.

The center of the light marks the center of the spot. For use of this targeting light, a separate

power supply is necessary with 5 ... 30 V DC and a current of I  30 mA.

Measuring is possible while the LED targeting light is on. We recommend using a low supply

voltage to keep the thermal loading of the pyrometer small.

3.3 Optics

The pyrometers are equipped ex works with one of the following optics. These optics focus to a

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

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

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

The following drawing and table shows the size of the spots in mm in relation to the measuring

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

for measuring distance 0 is the aperture diameter of the optics.
