Product Overview
In the specialized world of laser optics, the AR Coated Cylindrical Concave Lens is a critical component designed to expand light along a single axis. Unlike spherical lenses, a Cylindrical Concave Lens possesses a plano-concave profile that acts only in one direction, transforming a circular laser beam into a precise, elongated line. The integration of high-efficiency coatings makes an AR Coated Cylindrical Concave Lens significantly superior to uncoated versions by maximizing light throughput and minimizing parasitic reflections.
Our AR Coated Cylindrical Concave Lens is engineered to meet the demands of high-accuracy imaging and scanning. By applying a Broadband Anti-Reflection (BBAR) or V-Coat to the Cylindrical Concave Lens, we reduce the surface reflectance from approximately 4% to less than 0.5%. This enhancement ensures that the AR Coated Cylindrical Concave Lens maintains peak energy efficiency, which is vital for applications where signal-to-noise ratio and laser power retention are paramount. Every AR Coated Cylindrical Concave Lens we produce undergoes rigorous optical testing to ensure the curvature and coating uniformity meet global industrial standards.
Applications & Advantages
The AR Coated Cylindrical Concave Lens is a cornerstone in modern photonics. Below, we outline the functional advantages and real-world implementations:
- Optimized Laser Line Generation: The primary role of an AR Coated Cylindrical Concave Lens is to generate high-quality laser lines for 3D scanning and alignment.
- Minimized Ghost Images: The specialized coating eliminates internal reflections that often plague standard cylindrical concave lenses, ensuring a clean, ghost-free output.
- Anamorphic Beam Shaping: In diode laser systems, an AR Coated Cylindrical Concave Lens is used to correct the inherent astigmatism of the source, creating a symmetrical beam profile.
- Widespread Application Fields:
- 3D Vision & Metrology: Utilizing the lens for structured light patterns in industrial inspection
- Optical Data Storage: Implementing precision cylindrical lenses to manage laser diodes in read/write heads
- Spectroscopy: The lens helps in spreading light across linear sensor arrays without losing intensity
- Life Sciences: Using cylindrical lenses to create thin "light sheets" for fluorescence microscopy
Frequently Asked Questions
Q1: Why is "AR Coating" specifically important for a Cylindrical Concave Lens?
Answer: Because a Cylindrical Concave Lens is often used in high-precision laser setups, reflections can cause back-feed into the laser diode or create interference patterns. An AR Coated Cylindrical Concave Lens virtually eliminates these issues, increasing the total transmission of the lens system to over 99%.
Q2: How does the ±0.005mm tolerance impact the AR Coated Cylindrical Concave Lens?
Answer: In compact laser modules, the AR Coated Cylindrical Concave Lens must be perfectly aligned. A ±0.005 mm diameter tolerance ensures that the lens fits securely in its mount, preventing mechanical drift that could tilt the laser line.
Q3: What wavelength ranges are available for an AR Coated Cylindrical Concave Lens?
Answer: We offer custom coatings for the AR Coated Cylindrical Concave Lens ranging from UV (266nm) to IR (10.6μm). Each lens is optimized for its specific operating band to ensure the lowest possible reflectance.
Q4: Can I get a 40/20 surface quality on a Fused Silica AR Coated Cylindrical Concave Lens?
Answer: Yes. We specialize in high-precision polishing for cylindrical lenses. For UV applications, an AR Coated Cylindrical Concave Lens made of Fused Silica with a 40/20 or even 20-10 scratch-dig is standard for our production line.
Q5: How do you check the axis alignment of an AR Coated Cylindrical Concave Lens?
Answer: Every AR Coated Cylindrical Concave Lens is inspected using an optical centration gauge to verify that the cylinder axis is perfectly parallel to the lens edges, ensuring the lens projects a straight, non-deviated line.
