RLU10 laser unit
RLU10 offers a laser frequency stability of ±50 ppb over any one hour time period, which offers performance levels suitable for the majority of ‘in air’ applications.
Features and benefits
Combining the RLU10 with Renishaw detector heads (RLDs) suitable for the required application offers the following features and benefits:
- Simple system architecture – utilising Renishaw’s unique fibre optic delivery system
- Rapid alignment – RLD detector heads allow for laser beams to be mounted directly to the measurement axis
- Compact and easy to set up – with minimal system footprint and installation time
