Overview
The HTLM30 Lens Mount is a precision-machined, fixed-position optical mounting solution engineered for stable, repeatable alignment of plano-convex, biconvex, meniscus, and achromatic lenses with diameters ranging from 25 mm to 50 mm. Designed in strict accordance with standard optomechanical interface conventions, it features a centered 30 mm clear aperture bore with integrated spring-loaded retaining rings and nylon-tipped set screws—ensuring secure clamping without surface marring or induced stress birefringence. Its rigid aluminum alloy (6061-T6) body provides high thermal stability and dimensional consistency across laboratory temperature gradients (15–30 °C), while the black anodized finish minimizes stray light reflection and enhances corrosion resistance. The mount conforms to the widely adopted 1.00″ (25.4 mm) optical axis height standard, enabling seamless integration into multi-component optical benches, kinematic platforms, and modular laser systems used in spectroscopy, interferometry, and beam conditioning applications.
Key Features
- Precision-machined 30 mm central bore with ±5 µm concentricity tolerance relative to outer mounting flange
- Adjustable retention mechanism: dual nylon-tipped M3 set screws + removable stainless-steel retaining ring (included)
- Standardized 1.00″ (25.4 mm) optical axis height—compatible with Thorlabs, Newport, and Standa rail-based optical tables
- Integrated M4 and M6 threaded holes on base plate for versatile panel or breadboard mounting
- Black hard-anodized surface (Type II, 15–20 µm thickness) meeting MIL-A-8625F specifications
- No-tool lens insertion/removal design optimized for rapid setup in teaching labs and prototyping environments
Sample Compatibility & Compliance
The HTLM30 accommodates uncoated, AR-coated, and metallic-dielectric coated lenses up to 25 mm thick, including BK7, fused silica, CaF₂, and SF10 substrates. It supports both plano-convex and doublet configurations without vignetting when used within its specified diameter range (25–50 mm). All mechanical tolerances comply with ISO 2768-mK general tolerancing standards. As a passive optomechanical component, the mount requires no electrical certification; however, its material traceability documentation (including RoHS 2011/65/EU and REACH SVHC compliance declarations) is available upon request for GMP-aligned cleanroom installations and ISO/IEC 17025-accredited calibration laboratories.
Software & Data Management
This is a purely mechanical mounting device with no embedded electronics, firmware, or software dependencies. No drivers, SDKs, or configuration utilities are required. Integration into automated optical alignment workflows is achieved via third-party motion controllers (e.g., Thorlabs KDC101, Newport ESP301) using standard M4/M6 mounting interfaces. Mechanical CAD models (STEP and IGES formats) and GD&T drawings—including geometric tolerancing for runout (<0.01 mm), flatness (≤0.005 mm), and perpendicularity (≤0.01°)—are provided for system-level modeling in Zemax OpticStudio, CODE V, or SolidWorks assemblies.
Applications
- Laser cavity construction and external cavity diode laser (ECDL) alignment
- Fourier transform infrared (FTIR) spectrometer source optics positioning
- Collimation and focusing stages in OCT and confocal microscopy beam paths
- Undergraduate and graduate optics teaching labs—used in Maltese cross, Newton’s rings, and interference experiments
- Industrial machine vision illumination modules requiring stable lens registration
- Integration into custom-built Shack-Hartmann wavefront sensors and Hartmann-Shack arrays
FAQ
Is the HTLM30 compatible with vacuum environments?
No—standard anodization and non-vacuum-rated adhesives used in assembly preclude use in UHV or HV systems. Vacuum-compatible variants (with bare aluminum or electropolished SS304 bodies) are available under OEM agreement.
Can I mount a 50 mm lens without edge vignetting?
Yes—the internal chamfer and recessed retaining ring geometry maintain full clear aperture access at 50 mm diameter, assuming lens edge thickness ≤22 mm.
Does the mount include locking screws and retaining rings?
Yes—each unit ships with two M3 × 8 mm nylon-tipped set screws and one 30 mm OD stainless-steel retaining ring (ANSI B18.6.2 compliant).
What is the maximum torque specification for the mounting screws?
Maximum recommended tightening torque is 0.35 N·m for M3 set screws to prevent thread stripping and optic slippage.
Is ISO 10110 surface quality data provided for the bore interior?
No—bore surfaces are mechanically finished to Ra ≤0.8 µm but not polished to optical-grade scratch-dig specifications; intended for mechanical centering only, not direct beam passage.
