Overview
The HTLM50 Lens Mount is a precision-engineered optical mounting solution designed for stable, repeatable alignment and secure mechanical fixation of plano-convex, biconvex, or meniscus lenses with diameters ranging from 25 mm to 50 mm. Built on the principle of three-point kinematic constraint, this fixed-mount design eliminates parasitic tilt and axial shift under thermal or vibrational load—critical for maintaining collimation integrity in laser beam delivery systems, interferometric setups, and imaging train assemblies. Its standardized optical axis height (typically 1.00″ or 25.4 mm above base surface, compatible with industry-standard optical tables and rail systems) ensures seamless integration into modular optomechanical platforms. Constructed from black-anodized aluminum alloy (6061-T6), the mount balances dimensional stability, non-magnetic properties, and low thermal expansion coefficient (23.6 × 10⁻⁶ /°C), making it suitable for both ambient-lab and temperature-stabilized environments.
Key Features
- Three-screw clamping mechanism with calibrated torque retention—ensures uniform radial pressure distribution without lens edge chipping or stress-induced birefringence
- Interchangeable inner rings (sold separately) enable rapid reconfiguration for 25 mm, 30 mm, 40 mm, and 50 mm lens diameters within the same base housing
- Standard M4 and M6 tapped holes on base plate facilitate rigid attachment to breadboards, posts, translation stages, or custom optical benches
- Black anodized finish provides >95% surface light absorption, minimizing stray reflections in high-dynamic-range optical paths
- Centering accuracy ≤ ±5 µm (verified via autocollimation test with He–Ne reference beam) supports alignment-critical applications such as cavity stabilization and wavefront sensing
Sample Compatibility & Compliance
The HTLM50 accommodates lenses fabricated from fused silica, BK7, SF10, CaF₂, and IR-transmissive materials (e.g., ZnSe, Ge) up to 25 mm thick. It complies with ISO 10110-7 (surface form tolerances) and MIL-PRF-13830B (scratch-dig specifications) for mounting interface geometry. While not certified to ISO 9001 at the component level, the mount is supplied with full traceability documentation—including batch-specific dimensional inspection reports—supporting GLP-compliant lab workflows. Its passive mechanical design requires no electrical interface or firmware, eliminating electromagnetic interference (EMI) concerns in sensitive quantum optics or ultrafast laser laboratories.
Software & Data Management
As a purely mechanical mounting platform, the HTLM50 does not incorporate embedded electronics, sensors, or software interfaces. All alignment data—such as angular deviation, centering offset, or repeatability metrics—is captured externally using standard metrology tools: digital autocollimators (e.g., Thorlabs ACL250), optical levers, or coordinate measuring machines (CMMs). Integration with LabVIEW or MATLAB-based alignment automation systems is achieved via programmable motorized rotation/translation stages mounted beneath the HTLM50 base—enabling closed-loop active alignment protocols compliant with ASTM E2912 (Standard Practice for Optical Alignment Verification).
Applications
- Laser cavity construction (Ti:sapphire, DPSS, fiber lasers) requiring sub-arcsecond pointing stability
- Fourier transform spectrometer (FTS) fore-optics where lens decentering induces asymmetric apodization
- Quantitative phase imaging (QPI) systems utilizing off-axis digital holography
- Educational optics labs—used in undergraduate experiments on Gaussian beam propagation, ABCD matrix modeling, and aberration analysis
- Industrial machine vision calibration rigs where lens position repeatability must meet ISO 10110-5 tolerance classes
FAQ
Is the HTLM50 compatible with vacuum environments?
Yes—when assembled with stainless steel fasteners (M4/M6 UNC screws, grade 316), the mount has been validated for operation at pressures down to 10⁻⁶ mbar without outgassing-induced contamination.
Can I use this mount for aspheric lenses?
It is suitable for low-to-moderate numerical aperture (NA < 0.3) aspheres with convex surfaces; however, contact area optimization requires custom inner ring profiling—contact technical support for OEM machining options.
Does Han Ding provide calibration certificates?
Calibration reports (including centering error, base flatness, and thread concentricity) are available upon request and conform to ISO/IEC 17025 requirements when issued by accredited third-party metrology labs.
What is the maximum lens weight supported?
The mount maintains static stability for lenses up to 450 g; dynamic loading (e.g., in vibration-prone setups) is recommended ≤ 200 g to preserve long-term positional fidelity.
