Optical Post, Gear Rack, 7 in. Height, 1.5 in. Diameter, 1/4-20 Thread

Newport optical support rods are made of 1.5 in.(38.1 mm) diameter steel tubing, whose material properties allow for greater dynamic rigidity than aluminum designs, as well as thermal stability. The optical support rods are made round to < 1/1000 of an in. (12 µm) for precise, reproducible mating of rod-mounted components. The matte finish of the rods provides a low-reflectivity surface that is resistant to gouging, scratching and corrosion. The hollow-core construction provides even the standard (undamped) support rods with lower vibration amplitudes and higher resonant frequencies, often preferred for sensitive optical systems. The inherently greater stiffness and strength of these steel rods provides its support for larger and heavier optical components.

All optical support rods attach easily to tables either with an integral tie-down bolt or a steel ring base. We offer a wide selection of precision components including clamps, platforms and optics holders that mount interchangeably on the rods for complete component mounting flexibility.
