Types of Optical Survey Prisms
· Mini prisms are cheap and reliable, and are a good multi purpose
prism for short to mid range measurements.
· 360 prisms are simple to use for sharing prisms in a multi
station network and all angles have a shared center.
· Dual prisms are reliable shared prisms with shared centers. They
are less expensive than 360 prisms, but have to be aimed at each
total station in a network.
· Full size reference survey prisms are ideal for high range
precision monitoring and can be used to calibrate a monitoring
network
Optical Survey Prism Installation
Monitoring prisms should be installed using the following
guidelines:
· Attached to a rigid structure that is sufficiently stiff as to
not move through a single monitoring cycle
· Located to minimize the effects of temperature and radiant heat
on a target
· Installed with clear sight lines back to the total station
· Avoid sight lines that require shooting through a fence or
another mesh
· Avoid sight lines shooting just past corners which can cause
refraction
· Avoid sight lines that include a source of heat that can cause a
heat shimmer
