Replacement O-Ring Our Ideal Spectroscopy Optical Arm Assembly, Goes Between The Brewster's Window Mount And Main Optical Arm

This O-ring is a replacement part for our Ideal Vacuum optical arm assemblies, it is used to create the vacuum seal between the Brewster's window mount & main optical arm, it is made of Viton. Our Ideal Spectroscopy optical arm assemblies are precision-engineered for superior light control. Unlock the full potential of your spectroscopy and optical experiments, they are designed to optimize laser light interaction within vacuum chambers while minimizing unwanted background noise, greatly elimating the laser scatter that is generated when the beam passes through the exit window.
