Overview
The HTMM25-O Open-Type Two-Dimensional High-Stability Mirror Mount is a precision optical positioning platform engineered for rigorous laboratory and industrial alignment applications requiring sub-microradian angular stability and repeatable translational adjustment. Designed around a rigid, low-thermal-drift aluminum alloy base with hardened stainless steel adjustment mechanisms, this mount employs orthogonal kinematic coupling—featuring two independent, backlash-free differential micrometer drives—to enable precise, decoupled control of mirror tilt in pitch and yaw axes. Its open-frame architecture eliminates mechanical shadowing and facilitates unobstructed beam access, making it ideal for multi-beam interferometric setups, ultrafast laser alignment, and compact optical cavity construction. Unlike closed-body mounts, the HTMM25-O’s exposed mechanism allows direct visual verification of actuator engagement and enables integration with external position sensors or vacuum-compatible modifications when required.
Key Features
- Open structural design with full optical access from all four sides—no beam obstruction or stray light trapping
- Dual-axis angular adjustment via calibrated 10-µm resolution differential micrometers (pitch and yaw), each with locking thumbscrews for long-term positional retention
- Optimized for standard Ø25 mm and Ø25.4 mm (1 inch) optics; compatible with industry-standard retaining rings and spring-loaded kinematic contact points
- Base plate features multiple M4 and M6 tapped holes arranged in a 25 mm grid pattern for modular integration into breadboard or rail-based optical tables
- Surface-treated anodized aluminum housing provides corrosion resistance while maintaining dimensional stability across ambient temperature fluctuations (±0.5 °C)
- No internal springs or elastomeric elements—ensures zero creep and high hysteresis performance over >10⁴ adjustment cycles
Sample Compatibility & Compliance
The HTMM25-O accommodates plano and spherical mirrors, beamsplitters, waveplates, and other flat or low-curvature optical components up to 3 mm thickness and 25.4 mm diameter. It supports both front-surface and protected-aluminum coated substrates without risk of coating damage during clamping. While not certified to ISO 9001 at the component level, the mount complies with mechanical interface standards referenced in ISO 10110-7 (optical element mounting) and adheres to GD&T tolerances specified in ANSI/ASME Y14.5 for critical datum surfaces. Its design satisfies typical vibration isolation requirements for Class 1000 cleanroom environments and is routinely deployed in setups conforming to ISO/IEC 17025-accredited calibration laboratories.
Software & Data Management
As a purely mechanical, manual adjustment device, the HTMM25-O does not incorporate electronic actuators, encoders, or embedded firmware. Consequently, it requires no driver installation, firmware updates, or software licensing. All positional data—including initial setup coordinates, iterative alignment logs, and thermal drift observations—are documented externally using lab notebook systems compliant with GLP (Good Laboratory Practice) and FDA 21 CFR Part 11–enabled electronic record platforms. When integrated into automated optical benches, its fixed kinematic geometry enables accurate forward-modeling in ray-tracing software such as Zemax OpticStudio or Synopsys Code V, supporting traceable alignment workflows in regulated R&D environments.

FAQ
What is the maximum recommended optic weight for stable operation?
The mount is rated for optics up to 120 g without measurable sag-induced angular deviation (>0.5 µrad) over 24 hours.
Can this mount be used in vacuum environments?
Yes—when equipped with vacuum-compatible lubricants (e.g., Braycote 601 EF) and non-outgassing retaining hardware, it has been validated for use at pressures down to 1×10⁻⁶ Torr.
Is there a version with motorized actuators available?
HT offers the HTMM25-OM variant with integrated stepper-motorized micrometers (RS-485 interface, ±0.25 µrad repeatability); contact technical support for OEM integration specifications.
Does the mount include mounting hardware?
Standard delivery includes two M4 × 12 mm socket-head cap screws for base attachment and one set of Ø25.4 mm kinematic retaining ring + compression spring.
How is angular resolution quantified for this mount?
Based on micrometer lead screw pitch (0.5 mm/rev) and 100-division vernier scale, theoretical angular resolution is ≤1.2 µrad per scale division under ideal loading conditions.
