MKTA-T / MKTA-S Series Precision Optical Adjustment Mounts
• Thicker back plate and stronger springs than standard mounts for superior stability • Optical components secured via nylon-tipped setscrews or SM-threaded retaining rings • Designed for Ø1 inch and Ø2 inch optical components • 3 adjustment screws enable ±4° tip/tilt angular range • MKTA-T series compatible with lens tube assemblies (SM1/SM2) • Bottom M4 holes allow versatile mounting orientations
The MKTA series provides ±4° of tilt/pan angular adjustment. With all three adjusters engaged, a Z-axis translation up to 6.4 mm is achievable. Ideal for applications requiring precise angular alignment and high stability.

MS-A12 Precision Optical Mount (3-Axis)
• Compatible with Ø1/2 inch or Ø12 mm optical components, secured via nylon-tipped setscrew • Compared to standard dual-adjuster mounts, this mount features a thicker back plate, stronger springs, and enhanced stability • Three-axis adjustment with an angular range of ±4° • Uses M5 × 0.25 precision adjusters, offering 12.8 mrad/rev (0.73° per turn) adjustment resolution • M4 threaded mounting hole for rod post installation
MS-A12 is specifically designed with a more robust mechanical structure to improve stability during precise angular adjustments of small-diameter optics.
OST-K100 Three-Axis Precision Optical Mount (±4º ~ ±6º Adjustment)
• Equipped with M4 mounting hole for secure post installation • Three-axis manual micrometer adjuster design with ±4° to ±6° pitch/yaw adjustment range • Directly supports Ø1 inch optics, compatible with 2–10 mm thickness • Constructed from high-strength stainless steel for durability and precision • Comes with fine differential micrometers, each fitted with rotary knobs and locking nuts
