4.4 Telescope
The sighting telescope is mounted on the laser module. The telescope is designed to be used with a separation
between the eye and the eyepiece. This allows much easier operation of the system when operating over prolonged
periods.
The magnification is ×1.5 – 4. This is adjustable using the central zoom ring. The focus ring is on the end of the
telescope and can be adjusted to sharpen the image.
The telescope is aligned to be coincident with the laser beam at the unit’s maximum operating range. This means
that there is effectively a vertical offset between the centre of the cross hairs and the scanning laser of up to 60 mm
for near-field targets. This offset will generally only be noticeable at very short ranges.
WARNING: do not look through the telescope while using the laser pointer.
4.5 Yoke
The laser module is mounted between the pillars of the yoke. The yoke itself is mounted on the horizontal housing.
Encoders in the yoke and horizontal housing provide vertical and horizontal angular measurements respectively.
Angles are measured to one hundredth of a degree.
When mounted in the yoke, the laser has movement through −55° (below horizontal) to +90° (above horizontal) in
the vertical. The handle will restrict ranging at upper vertical angles but can be removed if required with a 6 mm hex
key.
Motorised movement of the yoke – and the laser module held within it – is controlled via the keypad. There are four
direction buttons on the right-hand side of the display: 2 = up, 4 = left, 6 = right, 8 = down. On pressing each button,
the motor will operate at the speed that has been set with the SPEED UP / SPEED DOWN buttons on the left of the
keypad. The speed buttons can be used at the same time that the unit is being moved. The default speed is the
slowest possible speed which is most commonly used for fine aiming.
Clutches also allow the system to be moved manually. Large movements of the laser module should be carried out
manually, whilst finer aiming can be achieved more precisely with the motorised controls.
