Overview
The MiXran Meg1004 Drum-Shaped Lens is a precision-engineered optical component designed for demanding beam shaping, collimation, and focusing applications in laser systems, fiber coupling setups, and compact optical instrumentation. Unlike conventional plano-convex or biconvex lenses, the Meg1004 features a cylindrical drum geometry—characterized by a curved cylindrical surface orthogonal to a flat base—enabling controlled astigmatic focusing with high axial symmetry and minimal wavefront distortion. Its design leverages classical Gaussian optics principles while accommodating tight mechanical integration constraints typical of OEM modules and space-constrained optomechanical assemblies. Manufactured from high-homogeneity optical glass (N-BK7 standard; fused silica optional), each lens undergoes deterministic polishing and interferometric verification to ensure λ/4 transmitted wavefront error (TWE) across its clear aperture. The drum profile allows direct mounting into rotary lens holders or press-fit alignment sleeves without additional centering hardware—reducing assembly complexity and thermal drift in multi-element systems.
Key Features
- Drum-shaped geometry optimized for low-aberration line focus generation and rotational symmetry alignment
- Multiple standard diameters (21.8 mm to 343.75 mm) and effective focal lengths (22.2 mm to 343.75 mm) supporting broad system scalability
- Three broadband anti-reflection coating variants: VIS (400–700 nm), NIR (650–1050 nm), and SWIR (1000–1650 nm), each achieving <0.25% average reflectance per surface
- Center thickness tolerance ±0.05 mm; surface quality rated 40-20 scratch-dig per MIL-PRF-13830B
- Mounting-ready cylindrical outer surface with ±2 µm roundness tolerance for direct integration into kinematic lens cells or custom housings
- Compliant with ISO 10110-1:2017 optical element specification standards and RoHS Directive 2011/65/EU
Sample Compatibility & Compliance
The Meg1004 is compatible with continuous-wave and pulsed laser sources operating within its designated coating bandwidths—including diode lasers (e.g., 405 nm, 635 nm, 785 nm, 1064 nm, 1550 nm), Ti:sapphire oscillators, and fiber-coupled supercontinuum sources. Its fused silica variant supports high-power applications up to 5 J/cm² at 10 ns pulse duration (1064 nm, 10 Hz), while the N-BK7 version is qualified for ambient temperature operation (−20 °C to +70 °C) under ISO 9022-3 environmental testing. All units are supplied with individual interferometric test reports traceable to NIST-calibrated phase-shifting interferometers. Documentation includes material certificates, coating spectral curves, and conformance statements aligned with ISO/IEC 17025-accredited calibration practices.
Software & Data Management
While the Meg1004 is a passive optical component, MiXran provides comprehensive digital support for system integration. Customers receive downloadable Zemax OpticStudio-compatible .ZAR files for all standard configurations, including full surface sag tables and coating dispersion models (Sellmeier coefficients). A dedicated web portal grants access to spectral reflectance datasets (CSV format), mechanical drawings (STEP and PDF), and GD&T annotations compliant with ASME Y14.5-2018. For regulated environments—such as medical device OEMs or defense contractors—MiXran supplies audit-ready documentation packages meeting FDA 21 CFR Part 11 electronic record requirements, including revision-controlled release notes and change history logs.

FAQ
What materials are available for the Meg1004 lens?
Standard material is N-BK7 (Schott catalogue #845000); fused silica (Suprasil 300) and CaF₂ are available upon request with extended lead time.
Can the Meg1004 be customized with non-standard focal lengths or coatings?
Yes—MiXran offers engineering support for custom EFLs (±0.5% tolerance), hybrid coatings (e.g., dual-band VIS+NIR), and substrate-specific thermal expansion matching (CTE tuning). Minimum order quantity applies.
Is there a mounting recommendation for vibration-sensitive setups?
We recommend kinematic three-point contact mounts with elastomeric isolation pads (Shore A 40–50) and torque-controlled fastening (0.15–0.25 N·m) to minimize stress-induced birefringence.
How is surface cleanliness verified prior to shipment?
Each unit undergoes automated particle counting per ISO 14644-1 Class 5 cleanroom protocols and solvent-free dry nitrogen purge; certification includes particle count report per ISO 10110-7 Annex B.
Do you provide ISO 17025-certified test reports?
Yes—traceable wavefront error, surface flatness, and coating performance reports are issued by MiXran’s in-house ISO/IEC 17025:2017 accredited metrology lab (CNAS Certificate No. LXXXXX).
