Standa Equipment Catalog

The compact modular dynamic vibration isolation system provides vibration isolation for six degrees of freedom. The feedback system is based on force sensors that provide isolation not only from external influences on the system (building vibrations), but also from internal vibrations occurring within the system itself.

The stiffness of the system is 500 times greater than the stiffness of a similar passive system, thus ensuring higher stability in position and direction. The absence of resonances at low frequencies, which are present in all passive systems, allows the system to be used for vibration isolation in unfavorable conditions.

The system is ideal for precision Fabry-Perot interferometers and tunneling microscopes, and maximizes performance from these systems. Successfully used in experiments with high sensitivity requirements, such as the fabrication of monomolecular films using the Langmuir-Blodgett technique.

• Steel Optical Rails
• Steel Rail Carriers

The optical rails have a small height and are made of hardened steel. The rails have a grid of M6 threaded holes and 6.4 mm through-holes. The holes and slots are used for mounting on optical boards, optomechanical elements and for interconnecting with each other.

The steel platform has additional top rails pointing perpendicular to the lower main rails. The platform allows to fix the part to the rail, to easily move it along the optical rail, to change and fix its position in the direction perpendicular to the rail within ±15 mm.

The great rigidity, resistance and strength of the steel allow the rods to hold heavy weights with high stability. Consists of a stainless steel tube filled with vibration dampening plastic. Even without the use of external damping elements, the rods will have a high resonant frequency and small vibration amplitudes. Steel provides strength and temperature stability.

• Brackets
• Adjustable mounting block

The bracket is a rigid plate bent at an angle of 90°. It is used for fixing translators during vertical movement. It allows to place the elements fixed on the rod parallel to the table surface, to create height-adjustable bases for fixing optical elements.

Adjustable mounting block is a platform that is attached to vibration-damping rods. The platform has a grid of M6 and M4 holes for attaching components. The orientation of the platform is adjusted by 4 screws within 5° at the corners. The same screws are used to fix the platform to the vibration damping rods.

The clamping holder allows to fix optics of any shape and configuration: round and rectangular, with negligibly small aperture and even at large beam angles. The upper support is fixed in the desired position by means of a fixing screw. This allows rigid fixation with little pressure on the object to be fixed.

The cassette holder allows you to extend/retract the filter ring mounts, thus exposing the filter to the beam. This allows different combinations of filters to be used. Two holder models are available - for 25.4 mm or 50.8 mm diameter optics. The maximum thickness for 25.4 mm diameter filters is 4.5 mm, for 50.8 mm diameter filters it is 4 mm.

Provides mounting for prisms, beam splitters, etc. The holder is manufactured with metric dimensions, and comes complete with adjusting screws that press the holder platform against hardened steel supports to ensure repeatable adjustment.

The top-adjustable optics holder is designed to minimize the wavefront distortion created by the holder. In conventional holders, the mirror is pressed sideways by a retaining screw. Radial forces acting on the mirror cause parasitic wavefront distortions such as astigmatism. Uniformly distributed forces acting along the optical axis do not cause such distortions. This holder is ideal for industrial applications (laser resonators, optical subsystems, circuits in confined spaces) due to its high stability.
