7) Objective Lenses
7.1) Front Condenser Lens
POSITION DRAWING OF CONDENSER SYSTEM SEE PAGE 11
In the HMI-projector BP 12 Platin 3 different interchangable multicoated front
condenser lenses are used depending upon the applied projection ojectives.
Order Code: 12410, Ø 320 mm/ f= 400 mm for Objectives f= 11; 13, 5; 18; 22; 27 cm,
Order Code: 12411, Ø 320 mm/ f= 500 mm for Objectives f= 33; 40; 50; 60 cm,
Order Code: 12412, Ø 320 mm/ f= 677 mm for Objectives f= 80 und 125 cm
7.2) Projection Objektives
PROJECTION DIAGRAM SEE PAGE 10
The projection objective lenses are mounted on the four support bolts and fixed by
the four wing nuts. The focal length (f) of the required projection objective depends
on the throwing distance and the desired picture width. It may be selected by using
the
projection
diagram
or
the
calculating
tool
on
our
homepage
http://www.pani.com/support/smart assistance. To set the sharpness move the
projection objective along the optical axis. The fucus position is fixed by means of
the two knurled nuts on either side of the projection objective.
NOTE:
The projection objectives 11 and 13,5 cm have a limited object field so they
are suggested under reserve to be used on a BP12 (i.e. 11cm: only ~Ø190mm of the
slide is visible)
7.3) Effect- and Vario Objectives
To complete the system of projection lenses, effects and vario-objective lenses are
available. Effects Lenses (focal lengths f= 80/ 100 mm, 110 mm, 150 mm, 180 mm,
250 mm and 310 mm
) have higher light output and well colour correction but
high distorsion and the light becomes stronger to the center. They are applied
to increase the depth effect and to obtain specific distorsion.
With the aid of the vario objectives with focal lengths of f=20-40cm/motorized and
f=30-60cm manual it is possible to enlarge or reduce images (in the given limits) at
different speeds. For example in touring theater where image sizes and projection
distances vary.
IMPORTANT NOTES:
Never operate the projector
without objective lens!
(dangerous area near the light
output of the projector)
WHEN USING WIDE ANGLE OBJECTIVE LENSES
Never keep the dimming shutter closed for longer than 1 minute when projecting
without slide
! (danger for objective and grey scale glass)
