ATOM data sheet - .PDF file.

ATOM is Renishaw’s non-contact optical linear and rotary incremental encoder system that combines miniaturisation with excellent dynamic performance and reliability. Applications for ATOM’s ultra-compact readhead include laser scanning, precision micro-stages, semiconductors, medical applications, DDR motors, microscopy and scientific research.

ATOM linear and rotary (angle) encoder systems feature integral setup LEDs that are usually sufficient for installation purposes. Customers with the most challenging setup requirements are now supported by an optional PC diagnostic software package for use in conjunction with a diagnostic hardware kit. The software is said to be particularly useful in situations where reliable visual assessment of the LED is difficult.

Renishaw’s ATOM diagnostic hardware kit is supplied in a carrycase to enable interface between any ATOM readhead variant and a standard USB port. The diagnostic kit includes a diagnostic dongle and associated hardware, connectors and a USB cable. Once the ATOM readhead is connected to the diagnostic system, the customer can view the signal amplitude and confirm that the reference mark is correctly calibrated via a graphical interface — which also allows the user to remotely calibrate the system and toggle the AGC status. Alternatively, an audible tone can be output in cases where the visual display is obstructed during readhead adjustment.

Sensors for co-ordinate measuring machines (CMMs) are an industry standard, from basic touch-trigger probes through to automated stylus and probe changers, motorised indexing probe heads, and revolutionary five-axis measurement systems.

Machine probes for CNC machine tools allow automated tool setting, workpiece set-up, in-cycle gauging and part inspection. Products include laser tool setters, contact tool setters, tool breakage detectors, touch probes and high accuracy inspection probes.

For motion control, Renishaw supplies laser encoders, optical linear encoders, optical angle encoders, optical rotary encoders, magnetic rotary encoders, magnetic chip encoders and magnetic linear encoders.

To analyse the static and dynamic performance of position-critical motion systems, Renishaw’s laser interferometer and environmental compensation system offers a linear measurement accuracy of 0.5 ppm, readings of up to 50 kHz and a linear measurement speed of up to 4 m/s, with a linear resolution of 1nm.

Renishaw’s Raman spectroscopy products exploit the Raman effect to identify and characterise the chemistry and structure of materials. A diverse range of analytical applications include pharmaceutical, forensic science, nanotechnology, biomedical and semiconductors.
