Product DescriptionProduct DescriptionHR Right Angle Retroreflectors are precision optical components designed for laser alignment, interferometry, and optical feedback systems, delivering >99.8% reflectivity at 0°–45° incidence across 350–2000 nm wavelengths. Constructed from high-stability BK7 or fused silica with broadband dielectric coatings, they ensure accurate 90° beam redirection with minimal angular deviation (<1 arcmin) and low scatter loss.As a china manufacturer, we offer:· Customizable coatings (dielectric, metallic) for UV, visible, or IR applications· Standard sizes (10x10 mm to 50x50 mm) and precision machining for non-square geometries· Stringent quality control for λ/8 flatness and 20-10 surface finish compliance· Engineering support for optimizing retroreflection efficiency in compact optical setupsProduct OverviewOptical DesignHR Right-Angle Retroreflectors consist of two perpendicularly aligned reflective surfaces (90° angle) that reflect incoming light back along its original path, regardless of incidence angle (up to 15° off-normal). The retroreflective geometry ensures stable beam return in dynamic environments. Material SpecificationsSubstrates:Fused Silica (Vis-NIR): 400–1700 nm transparency, ideal for precision metrology.Silicon (Mid-IR): 1–8 μm, suitable for 10.6 μm CO2 laser systems. Coatings:Dielectric (Narrow-Band): >99% reflectivity @ 633 nm (He-Ne lasers), 1064 nm (Nd:YAG).Metallic (Broadband): Protected silver (450–20,000 nm) or gold (2–20 μm) for IR applications. Manufacturing PrecisionAngle Accuracy: ±5 arcseconds (measured via autocollimator), ensuring <0.1 mrad beam deviation.Surface Flatness: λ/10 @ 633 nm, with edge chamfers (0.3 mm) to prevent mounting stress.SpecificationProduct:HR Right Angle RetroreflectorsMaterial:Fused Silica/SiliconAngle tolerance: <5arcsecDiameter Tolerance:+/-0.1mmBevel: Break sharp edgesFlatness (PV): <1/10L@633nmSurface Quality: 20-10Thickness Tolerance: +/-0.1mmKey FeaturesSelf-Aligning Beam RedirectionCompact Form FactorMaintains retroreflection for angles of incidence up to 15°, making them robust for misaligned input beams in industrial automation.Available in sizes from 6.35 mm (0.25") to 50.8 mm (2") cubic dimensions, with thicknesses matching aperture size for mechanical stability.High Reflectivity Across BandsVibration ResistanceDielectric: >99.5% @ specified wavelength (e.g., 785 nm for Raman systems).Gold: >98% from 3–20 μm, consistent with thermal imaging requirements.Engineered with stress-relieved edges to withstand mechanical shocks (50 g, 11 ms) and vibrations (20–2000 Hz, 1.5 g), critical for aerospace applications.ApplicationsLaser Alignment SystemsAutonomous VehiclesIndustrial Robotics: Maintain precise beam paths in robotic welding cells, ensuring <50 μm positional accuracy over 10 m distances.Optical Tables: Serve as reference retroreflectors in Michelson interferometers for nanometer-scale displacement measurements.LiDAR Systems: Redirect 905 nm/1550 nm laser pulses in solid-state LiDAR arrays, improving signal-to-noise ratio by 20%.ADAS Calibration: Used in automotive test labs to validate radar-lidar synchronization via retroreflective targets.Aerospace & DefenseMetrology InstrumentsInertial Navigation: Stabilize laser gyroscopes by reflecting beams in closed-loop optical cavities, reducing drift to <0.1°/hr.Satellite Communication: Align free-space optical links (800–1600 nm) between satellites, compensating for orbital vibrations.Coordinate Measuring Machines (CMM): Enable non-contact position tracking of CMM probes with sub-micron resolution.Laser Trackers: Extend measurement ranges up to 100 m by reflecting beams off retroreflectors on target objects.FAQFAQ of HR Right Angle RetroreflectorsWhat is the maximum working distance for HR Right Angle Retroreflectors?Effective distance depends on laser power and detector sensitivity, but typical ranges are 50–200 m for 1 mW lasers in well-aligned systems. Can HR Right Angle Retroreflectors be used with polarized light?Yes, but dielectric coatings may introduce polarization-dependent loss (PDL). Specify polarization-insensitive coatings for PDL <0.1 dB for HR Right Angle Retroreflectors How to mount HR Right Angle Retroreflectors for minimal thermal drift?Use invar mounts (CTE: 1.5 ppm/°C) and torque-limited screws (0.5–1 N·m) to minimize thermal expansion effects. Do you offer anti-reflective coatings on non-reflective surfaces?Yes, back surfaces can be AR-coated (≤0.2% reflectance) to eliminate parasitic reflections in multi-pass optical systems.Company ProfilePackaging & ShippingPACKINGCarton, Blister, FoamPayment MethodsT/T, L/C, Western Union, Cash, Credit Card, Paypal, Alipay, MoneyGram, Assurance payment......
