Lens types
Lenses with smaller focal length are called wide-angle lenses,
they can also be used at short operating distances, but produce
intense distortion of the image. At a suitable distance, they have
a large image field.
Lenses with a long focal length are called telephoto lenses; they
have a large magnification but cannot be focused at close
range, so macro lenses are used that can be focused by means
of large telescopic extensions or intermediate rings. At a suitable
distance, they have a small image field.
In the case of telecentric lenses, at least the optical path at the
object end is almost parallel (i.e. parallel projection). This means
that objects at different distances are depicted in the same size.
Objects can, however, only be displayed that are smaller than
the diameter of the lens. It is not possible to adjust the range of
focus with these lenses.
The optical characteristics can be restricted by means of optical
filter glasses to counteract distortion in the image. Colored filters
limit the spectral range, gray filters limit the light intensity and po-
larization filters restrict the transmission plane. Filters of this type
can be attached either by using the internal thread or the flange
on the front of the lens. The holder for the filter glass is designed
to fit the lens.

Suitable lenses: 6GF9001-1BE01, …-1BL01, …-1BF01, …-1BG01, …-1BH01, …-1BJ01, …-1BK01
6GF9001-1BV
Filter for utilizing the mini lenses in the limited field of view
Infrared filter
Function: Visible light is largely or completely filtered out, infrared light can pass through.
Application: When used with infrared lamps, it is possible to achieve independence from daylight.
Suitable lenses: 6GF9001-1BL01, …-1BF01, …-1BG01, …-1BH01, …-1BJ01
6GF9001-2AD
Blue filter
Function: Blue light can pass through.
Application: e.g. to improve the visualization of structures.
Suitable lenses: 6GF9001-1BL01, …-1BF01, …-1BG01, …-1BH01, …-1BJ01
6GF9001-2AE
Polarization filter
Function: Filters out light which is directed at right angles to the polarization direction of the filter.
Application: e.g. to reduce reflections from metal.
Suitable lenses: 6GF9001-1BL01, …-1BF01, …-1BG01, …-1BH01, …-1BJ01
6GF9001-2AF
Daylight filter
Function: Visible light can pass largely undiminished, and frequencies above and below
(infrared light and ultraviolet light) are filtered out.
Application: The filter is used to protect the image sensor in the camera from laser light
to the extent that this is outside the visible spectrum.
