High Power Cylindrical Lens Array MLAR22-075-P10-B

Overview

This High Power Cylindrical Lens Array is a refractive microlens array for one-dimensional beam shaping and homogenization. Cylindrical lenslets are figured directly into a S-TIH53 substrate in a single-sided cylindrical lens array, giving a 1 mm array period and an f-number of 0.571. The 22×10.9×2 mm element offers a 20×8.9 mm clear aperture and spreads the incident beam over a 75 ° divergence angle across the 770-1070 nm operating range. Microlens focal length: 0.56 mm @808 nm; 0.571 mm @1064 nm. The element is a solid single-material S-TIH53 component with no polymer or adhesive layer in the beam path, consistent with its high-power designation.

Applications

• High-power laser beam homogenization and flat-top profile generation
• One-dimensional line generation and structured illumination
• Diode-bar and fiber-laser beam shaping
• Laser materials processing and line-beam illumination
• Uniform illumination in lithography and imaging systems

Construction & Performance

The lenslets are arranged in a single-sided cylindrical lens array on a S-TIH53 blank of 22×10.9×2 mm outer dimensions, with a 0.46 mm radius of curvature per lenslet. The surfaces carry AR coating Ravg <1% @770 nm-1070 nm. Transmittance is >99%. Key specifications for this model:

Storage & Handling

Handle the array by its edges and avoid contact with the clear aperture. Keep the microlens surfaces free of dust and fingerprints; when cleaning is required, use clean optical-grade solvents and lens tissue, wiping along the lenslet axis. Note the orientation of the lenslet axis when mounting so the shaped beam lies in the intended plane. Store in the original container in a clean, dry environment, away from direct sunlight, condensation and corrosive vapors.
