Fibre optic laser encoder products
With a laser frequency stability of ±50 ppb over any one hour period, the RLU10 is a practical and cost effective solution for the majority of 'in-air' applications.
For applications which require the highest measurement performance, such as vacuum applications. The RLU20 offers a laser frequency stability of ±2 ppb over any one hour period.
The RLD10-PMI (Plane Mirror Interferometer) is a double pass system configured for applications where a plane mirror is required (for example XY stage applications).
The RLD10-RRI (Retroreflector Interferometer) is a single pass interferometer configured for applications where a retroreflector is required (for example longer range or higher speed applications).
The RLD10 DI (Differential Interferometer) is a double pass interferometer system designed to provide a differential measurement. Ideally suited for vacuum chamber applications.
The RLD10-XX (no internal interferometer) detector head is designed with no internal interferometer optics. This allows the head to be used in a sequence with specialist optics to achieve linear, angular and straightness measurements.
Utilises environmental sensors to monitor a machine's ambient environment and provides real-time compensation of the position feedback signals.
Accepts differential analogue 1 Vpp sine / cosine signals and interpolates by 4096 to provide a 36-bit parallel format output with resolution capability of 38.6 picometres at 1 m/s.
Using a 1 Vpp sine / cosine signal from an RLE system the RLI20-P provides the interface to Panasonic (MINAS A5 series) controllers.
The RSU10 USB interface accepts 1 Vpp sine / cosine signals from an RLE system, interpolates by 16,384 and provides a position reading via a USB port.
The REE range of interpolators offers a simple 'plug and play' solution for lower levels of signal interpolation, increasing the resolution of the digital quadrature output signal by a factor of more than 20.
Highly reflective plane mirrors with easily adjustable mirror mounts. Renishaw supplied plane mirrors are manufactured on a low thermal expansion glass substrate and have a hard oxide, dielectric coating.
The periscope assembly increases the offset between the measurement and reference beams of the RLD10-X3-DI differential interferometer detector head.
Offers the ability to keep the entire measurement path within the vacuum environment when used with the RLD10-A3-XX detector head.
