Never look directly into the laser beam. The beam and spot can be watched safely from side.
Also, make sure that the beam will not be reflected into eyes of people by mirrors or shiny
surfaces.
The laser targeting light can be switched on and off by pressing the button of the rear cover of
the housing.
Note: The laser warning signs on the pyrometer should be easily viewable at all times,
even after it has been installed.
The laser targeting light can also be switched on and off by using an external contact (see
section 3.1.1 Pin Assignment) or through the InfraWin software. If it is not switched off by one
of the above-mentioned methods, it will be switched off automatically after approximately
2 minutes.
To prevent damage to the laser, the targeting light is also switched off automatically if the
internal temperature of the pyrometer exceeds 61 °C. It can only be used again once the
temperature falls below 61 °C.
3.3 Optics
3.3.1 Spot Sizes
The IS 6 Advanced / IGA 6 Advanced has a Vario optics, which can be manually adjusted at all
distances between 210 mm and 5000 mm.
The table of Spot Sizes in Relation to Measuring Distance shows examples of the pyrometer’s
spot size M [mm] in relation to the measuring distance a [mm] (min. 90% of the radiation
intensity). Increasing or decreasing the measuring distance will change the spot size.
Note: Since these are 1-color (mono) pyrometers, they can measure objects at any
distance (whether focused or non-focused). However, the object has to be bigger than,
or at least as big as, the spot size of the pyrometer in the measuring distance.
