Beam Delivery Arms -P I V
Applications
 In
laser based optical measurement techniques, beam delivery is greatly
simplified with the use of Denfotex
Light
Systems' articulated arms and
beam turning assemblies. Particularly in Particle Image Velocity (PIV)
applications, our exceptionally rugged carbon-fibre based arms provide
the flexibility to permit rapid measurement turnaround without being
constrained to fixed experimental arrangements. Custom products for
all commonly used measurement wavelengths are available, using high energy
laser coated mirrors from the best suppliers.
