Description
The Rotator25-Optic from MultiFields' 25mm Series is a precision-engineered, closed-loop rotary stage designed for optical and cryogenic applications in demanding research environments. Featuring a compact 30 × 23 × 14.5 mm design and an integrated Φ6 mm optical aperture, this stage enables precision rotation of optical components or beams under extreme conditions. Built with non-magnetic materials such as pure titanium and BeCu, it supports operation within magnetic fields up to 18 Tesla.
Engineered for ultra-high vacuum (UHV) levels down to 2E-11 mbar and temperatures as low as 30 mK, the Rotator25-Optic is ideal for integration into dilution refrigerators and other cryogenic setups. With 360° endless rotation, 1.5 N·cm torque, and a closed-loop resistive sensor providing 10 m° resolution, this device offers exceptional repeatability and stability for fine rotational positioning.
Available in multiple optional versions (.HV, .ULT, .UHV, .ULT.UHV), the Rotator25-Optic delivers flexible performance across a wide range of scientific and photonic applications.
