The Newport M-37 is a precision kinematic tip-tilt rotation stage engineered for three-axis angular positioning of optical components and experimental assemblies. This multi-axis platform delivers independent tip, tilt, and rotation control via spring-preloaded, hardened steel ball pivots and spherical-tipped adjustments. The design eliminates backlash while maintaining smooth actuation across demanding laboratory and alignment applications.

– Key Features
• Hardened and polished steel ball pivot construction with kinematic design principles
• Spring-preloaded spherical tips acting on hardened steel seats for repeatable positioning
• Full three-axis angular freedom without mechanical coupling
• Smooth, backlash-free operation across full adjustment range
• Direct micrometer actuation for fine angular control
– Typical Applications
• Optical beam steering and component alignment
• Laser cavity and resonator tuning
• Spectroscopic instrument setup and calibration
• Experimental optical path optimization
– Compatibility & Integration
The M-37 integrates with linear translation stages such as the 423 and 443 series. When stacked with an XYZ translation platform, the M-37 provides six degrees of freedom for complete spatial and angular positioning.
