Overview
The MiXran Meg1042 Right-Angle Laser Prism is a precision optical component engineered for high-stability beam deviation in demanding laser alignment, interferometry, and optical path folding applications. Based on the principle of total internal reflection (TIR), the Meg1042 directs incident collimated light by exactly 90° with minimal wavefront distortion and polarization-dependent loss. Unlike mirror-based deflection solutions, this prism eliminates air-gap sensitivity, back-reflection artifacts, and mechanical mounting drift—making it ideal for compact, alignment-critical systems such as fiber coupling stages, confocal microscopes, LIDAR receiver optics, and OEM laser modules. Constructed from high-homogeneity N-BK7 or fused silica substrates (depending on spectral and thermal requirements), each unit undergoes rigorous metrology validation—including interferometric angle measurement, surface flatness verification (λ/10 at 633 nm), and spectral reflectance profiling across its designated wavelength bands.
Key Features
- Precision right-angle geometry with angular deviation ≤2 arcseconds—certified via autocollimation interferometry
- Broadband anti-reflection (BBAR) coating optimized for low residual reflectance (<0.25% per surface) at 532 nm, 633 nm, and 785 nm—enabling multi-wavelength system integration
- Surface quality rated to 10-5 scratch-dig per MIL-PRF-13830B, ensuring compatibility with high-power CW and pulsed laser systems
- Clear aperture ≥90% of nominal side length, supporting efficient throughput in space-constrained optical layouts
- Thermally stable design with coefficient of thermal expansion (CTE) matched to standard optomechanical mounts—minimizing stress-induced birefringence
- RoHS-compliant manufacturing and ISO 9001-certified production traceability for regulated laboratory and industrial environments
Sample Compatibility & Compliance
The Meg1042 is compatible with common laser sources including DPSS (532 nm), HeNe (633 nm), diode-pumped solid-state (785 nm), and Ti:sapphire tunable systems. Its AR-coated variants are validated per ISO 10110-7 for surface imperfections and per ISO 10110-3 for transmitted wavefront error. All units meet EN 61000-6-3 (EMC emission) and EN 61000-6-2 (immunity) standards when integrated into compliant host systems. For medical or aerospace applications, documentation packages include full material certifications (e.g., Certificates of Conformance per ASTM E1316), coating durability reports (per MIL-C-48497A), and batch-level interferometric test records.
Software & Data Management
While the Meg1042 is a passive optical element, its performance integration is supported through MiXran’s Optical Component Integration Toolkit (OCIT)—a downloadable resource containing Zemax OpticStudio and CODE V prescription files (.zmx, .seq), coating spectral data (.txt), and GD&T-aligned STEP models. Each product shipment includes a digital Certificate of Calibration (PDF + XML) with unique serial traceability, wavelength-specific reflectance curves, and interferometric angle deviation maps. Data conforms to ASTM E2917-22 for calibration record retention and supports GLP/GMP audit readiness via secure cloud-accessible archives (optional subscription).
Applications

- Fiber-to-free-space coupling in quantum optics setups where back-reflection suppression is critical
- OEM integration into portable Raman spectrometers (785 nm excitation) and bioimaging endoscopes
- Alignment fiducials in vacuum-compatible optical tables and cryogenic optical benches
- Calibration reference in metrology-grade autocollimators and electronic theodolites
FAQ
What substrate materials are available for the Meg1042 series?
Standard delivery uses N-BK7 for visible/NIR applications; fused silica is available upon request for UV transmission or reduced thermal drift.
Can the Meg1042 be used with high-repetition-rate ultrafast lasers?
Yes—when specified with fused silica substrate and damage-tested coating, it supports pulse durations down to 100 fs at repetition rates up to 1 MHz (consult coating datasheet for exact fluence limits).
Is custom coating available outside the 532/633/785 nm bands?
Yes—custom V-coatings or ultra-low-loss broadband AR coatings (e.g., 400–1000 nm) can be quoted with lead time extension.
Do you provide mounting solutions or kinematic adapters?
MiXran offers compatible kinematic prism mounts (PM-RA series) and Ø1″ post adapters with ±1 arcmin tip/tilt adjustability—fully documented in the OCIT toolkit.
How is angular accuracy verified for each unit?
Each prism undergoes dual-axis autocollimation using a Zygo Verifire™ MST interferometer; raw angle deviation data is included in the Certificate of Calibration.
