3.5 Optical head
Depending on the application, the instrument will be delivered with a small or a big optical
head.
Type
Ι
(small optical head, fixed adjusted): With very small
dimensions, the optical head Ι is suited for use in confined spaces. The
optics is adjusted ex works to one of the measuring distances
mentioned in the table in section
3.5.1 The mentioned spot size will
be achieved in exactly this distance (other distances can be realized on
request).
Type
ΙΙ
(large optical head, focusable): The optical head ΙΙ is
focusable, i.e. each measuring distance can be adjusted within the
mentioned limits to achieve the smallest spot size in the required
distance. The spot size at the shortest and longest distance is
mentioned in the table in section
3.5.1. Spot sizes at intermediate
distances have to be calculated by interpolation.
Type
ΙΙ
(large optical head, fixed adjusted): The fixed adjusted
optical head ΙΙ has a similar size as the focusable optical head ΙΙ but
with a fixed focusing distance (see table
3.5.1) as type Ι (other
distances can be realized on request).
Note: The optical heads can be changed against another from the same type.
A recalibration of the pyrometer is not necessary.

)
The aperture is the effective lens diameter of the optics. The aperture is dependent on the objective length which
changes if the focus distance is changed (only true for the focusable optical head II). The biggest aperture value belongs
to the fully extended objective, the smallest aperture value if the objective is turned to its smallest size. Intermediate
values have to be interpolated (e.g. calculating the spot size if the measuring distance varies from the adjusted value).
