Tungsten Gamma Ray Collimators

Collimators contain and direct the beam of radiation during exposure. This results in improved radiograph quality and safer operating conditions.  Tungsten panoramic collimators consist of a stainless steel housing containing two tungsten inserts. Tungsten directional collimators direct the radiation beam from a side port as a 60° conical side throw. All of our collimators can be attached directly to a SENTINELTM source guide tube.  A wide range of collimators have been developed to meet the variety of applications and techniques used.
