A unique LTHR, equipped with a 50/50
beam-splitter on the flat mirror side is required. The LTHR is mounted such that the user can simultaneously
view the cross-hair from the collimator and the cross hair from the
gunsight. The alignment procedure
requires a high-resolution mechanical means to tilt and tip the gunsight to a
new position where the two cross hairs coincide with each other.
In
applications where more than one optical axis exists in a system, the PLX
Rotary Movement Devise (RMD) is recommended. The RMD enables a rotary connection between an LTHP, and
LTHR or any combination thereof. Such combinations can be utilized in conjunction with the configurations
shown in Figures 1. 2. and 3.
Figure 4. This
illustration shows the configuration of Figure 1 utilizing an additional LTHP
to enable variable distance of the optical axis. The distance “x” changes as a function of the angle between
the devices, thus enabling an unlimited amount of optical axis on one
plane. The RMD is supplied with
locking mechanism to ensure proper position at any bore-sighting axis.
The
LTHP and LTHR are invariant, high-accuracy monolithic optical tube assemblies
that enable perfect beam delivery. The tubes and the mirrors are made from low expansion glass such as
Pyrex and Quartz, and, as such, are not sensitive to temperature change. They utilize front surface reflection
to enable high reflectance at all wavelengths, from UV to far IR. PLX has qualified the tubes for
applications involving harsh military conditions, such as helicopter
battlefield conditions and space vehicle launch.
PLX can adapt its
Boresighting and Boresighting Verification Technology to meet your specific new
equipment or upgrade needs. For
