AR-Coated N-BK7 Optical Cylindrical Lenses for Laser and Imaging Systems

Material:

1.Optical Glass: These lenses are precision-manufactured from N-BK7 optical glass, a high-grade borosilicate crown material renowned for its exceptional clarity, uniformity, and stability.

2.Durability: N-BK7 glass provides excellent mechanical and environmental durability, ensuring reliable long-term performance in demanding optical systems.

Properties:

1.AR Coating: Featuring a multi-layer Anti-Reflective (AR) coating, these lenses minimize surface reflections and glare. This significantly enhances light throughput and image contrast by reducing stray light and ghosting.

2.High Transmittance: The combination of N-BK7 substrate and optimized AR coatings delivers very high transmittance across the visible and near-infrared spectrum, maximizing system efficiency and brightness.

3.Precision Optical Surface: The cylindrical optical surface is fabricated and polished to high tolerances, ensuring accurate wavefront control and consistent performance.

Functions:

1.One-Dimensional Beam Shaping: The cylindrical geometry focuses or expands light in only one axis. This critical function enables the transformation of laser beam profiles (e.g., circularizing elliptical diode outputs) and the creation of precise laser lines.

2.Anamorphic Imaging: In imaging systems, these lenses compress or expand an image in a single dimension, correcting for aspect ratio discrepancies or enabling specialized field-of-view formatting.

3.Astigmatic Correction: They are essential for correcting astigmatism in optical systems, including those using laser diodes, to achieve a diffraction-limited spot or a perfectly collimated beam.

Applications:

1.Laser Systems: Widely used for beam shaping in laser marking, engraving, and cutting systems; for fiber coupling and telecommunications; and for generating uniform lines in machine vision, alignment, and metrology.

2.Imaging & Spectroscopy: Integral components in confocal microscopes, optical coherence tomography (OCT), spectrometers, and anamorphic cinematography lenses for precise light control and image formation.

3.Scanning & Display: Employed in barcode scanners, laser printers, and certain projection display technologies where precise linear scanning or image manipulation is required.

4.Research & Medical Equipment: Found in scientific instrumentation and medical diagnostic devices where high-fidelity, one-dimensional optical processing is critical.
