FLS 25 Flat Rail System
Qioptiq (formerly LINOS)
Flat micro-optical bench system compatible with Nanobench optical bench system.
The result of consequent further development in the field of mechanical systems for microoptics applications is the rail system FLS 25. With this system, linear and planar structures can be realized and mounted optics with a diameter of 16 mm directly taken into a carrier. The compatibility with the LINOS nanobench system enables the application of a large number of structure components like mirror and prism adjusters, positioning units and fiber adapters. The optical axis of the total system is 20 mm above the work surface.

Rail FLS 25
The extruded profile with its high degree of straightness and low torsion also has a high degree of levelness due to the precise processing of all guide and bearing surfaces. The black anodized rail profile has oblong holes so that it can be attached to work surfaces with metric or inch standard threads as well as independent of the pattern. The rail FLS 25 is available in lengths of 50 mm to 500 mm.

Carrier FLR 25
The carrier FLR 25 serves for direct take-up of mounted optics with a diameter of 16 mm. The carrier is also equipped with four borings in a 16 mm pattern. These serves to take up the rods of the nanobench and are therefore the interface to this system. A large number of different structure components of the nanobench system can be mounted on the rail. A spring-mounted lever fixes the carrier on the rail. When the knurled head screw is loosened, the carrier can be moved easily and jerk-free due to the spring tension. By tightening the knurled screw, the carrier can be arrested in a position.

FLS 40 Flat Rail System
Qioptiq (formerly LINOS)
Flat micro-optical bench compatible to Microbench
The black anodized profiled rail FLS 40 features high linearity and low torsion. Thanks to additional, precise machining, all rail and support surfaces of the extruded profiled rails are exceptionally even. Slots in the profiled rails enable components to be assembled in a choice of metric or inch standard tapped hole patterns, and the rail positions to be easily shifted, independently of the tapped pattern. A ruler makes it easy to locate the components to ensure the reproducibility of their positioning.

The FLS 40 rail system is available in various lengths from 40 mm to 1,000 mm

  • High stability
  • Precise guide rail surfaces
  • Including ruler
  • Slots allow rails to be shifted to any position Independently of the tapped hole pattern
  • Abrasion-resistant black anodized surface
  • Material: aluminum alloy, black anodized
  • Mass: 1.0 kg/m
  • Straightness: 0.3 mm/m
  • Torsion: 0.2 °/m


X25 Profile system
Qioptiq (formerly LINOS)
The profile system X 25 is ideal for assembling linear and plane element systems.
By using the FLR 25 carrier of the rail system FLS 25 all mounted lenses and components of the LINOS Nanobench system can be assembled on this profile. The geometry of rail X25 enables the carriers to be positioned at 45° steps around the rails.
  • Octagonal profile system
  • High stability
  • Precise guide rail surfaces
  • Compatible with the LINOS Nanobench system with carrier FLR 25 of the rail system FLS 25
