LINOS Flat Rail System 40
The LINOS® Flat Rail System 40 is a compact and versatile solution for creating precise micro-optical benches. Its slim design supports space-constrained setups while maintaining high stability and accurate alignment of optical components. Ideal for research laboratories and industrial applications, the FLS 40 enables easy, reproducible positioning of mounted optics and supports efficient assembly of complex optical paths. Suitable for metrology, photonics, and experimental setups, this rail system provides the reliability and precision needed for consistent, repeatable results.
The LINOS Flat Rail System 40 features precisely machined guide surfaces for smooth carrier movement and exceptional linearity. Its slotted design allows flexible mounting and easy repositioning, independent of existing hole patterns.
- Integrated ruler for quick, reproducible component placement
- Durable black anodized finish for long-term performance

Application Example: Rail FLS 40, 200 and 40 mm long, with various FLR 40 Carriers.
