Linear positioning stage with preloaded ball-screw
Aerotech’s MPS75SLE linear position stage features a precision ground, preloaded ball-screw coupled with a low thermal expansion linear encoder, provides outstanding accuracy, repeatability and a positioning resolution capability to 25 nm. Anti-creep, crossed-roller bearings are designed to provide smooth travel and high-load capacity. The low thermal expansion (3.3 ppm/˚C) precision glass scale encoder results in high-accuracy and repeatable positioning over long periods of time. The linear encoder is available with amplified sine (1 Vpp) or 50 nm TTL digital outputs for easy integration.
MPS75SLE motor options include a dc servomotor with a high-resolution rotary encoder or a stepper motor. An optional mounting plate provides direct mounting to both English and metric optical breadboards, while the inherent mounting compatibility between all MPS stages results in simple development of multi-axis arrangements.
