Product Overview

Solving Complex Beam Profiles

While spherical lenses focus light into a point, cylindrical lenses focus light into a line. This unique property makes them indispensable for manipulating laser outputs. Whether you need to circularize an elliptical beam from a laser diode or create a sharp reference line for automated scanning equipment, our cylindrical lenses deliver exact, repeatable optical performance.

Maximized Photon Throughput & Durability

To ensure maximum energy transmission in your specific operating environment, we offer custom multi-layer coatings. From Broad-Band Anti-Reflective (BBAR) coatings for visible spectrum machine vision, to durable V-coats designed to handle the high laser damage thresholds required in industrial material processing.

Reliable, Ready-to-Integrate Optics

We understand that B2B procurement demands consistency. We deliver globally compliant, highly precise cylindrical optics directly to your factory or third-party integrators. Edges can be custom-chamfered and dimensions tightly controlled to guarantee a drop-in fit for your optomechanical mounts and laser modules.

Application & Engineering Integration


Figure 1: Zygo Interferometric Surface Analysis

Captured using industry-standard Zygo metrology, this interferogram confirms the exceptional optical fidelity of our cylindrical lenses. Manufacturing single-axis curved surfaces without edge roll-off or twisting requires advanced polishing techniques, and this data proves our commitment to uncompromising precision.

  • Exceptional Form Control: Achieves a precise PV 0.197λ (outperforming the λ/4 standard), ensuring the resulting laser line is perfectly straight and free from structural distortion.

  • Ultra-Smooth Surface: The outstanding RMS 0.022λ signifies minimal surface irregularities, effectively eliminating forward scatter and localized hotspots.

  • Engineering Impact: Delivers the sharp, high-contrast, and highly uniform beam profiling absolutely essential for critical 3D machine vision, laser scanning, and demanding metrology applications.

Metrology Analysis & Application Fit

  • Target Wavelength: From Deep-UV (using Fused Silica) to Visible (K9 Glass) and Mid-IR (ZnSe for industrial CO2 applications).
  • System Integration: Commonly used in pairs (cylindrical telescope) to alter the aspect ratio of an image or laser beam.
  • Primary Applications:
  • Laser line generators for 3D triangulation and profiling.
  • Barcode scanning and automated sorting systems.
  • Astigmatism correction in laser diode outputs.
  • Spectroscopy and slit illumination.

Custom Optomechanical Solutions

Aligning cylindrical lenses requires precision, as any rotational error around the optical axis will tilt the resulting laser line. Our engineering team can work closely with your CAD designs to supply custom rectangular or circular form factors, making mechanical registration and alignment in your optical barrels straightforward and secure.
