Highly stable laser interferometer with two parallel measuring beams for a wide variety of applications in the field of science and for industrial use. Due to differential measurement a remarkable stability for long-term usage and a compensation of the influences of air can be achieved.

 

 

 

Laser interferometer Model SP 2000 DI 

SIOS Laser interferometer model SP-2000-DI

Overview:

  • Beam distance 21 mm (other options for beam distances on request)
  • Temperature sensitivity < 20 nm / K
