Description
Plano-Concave Cylindrical Lenses are specialized optical components designed to manipulate light in one dimension. Unlike spherical lenses, which affect light in all directions, these lenses focus on altering the light path along a single axis. This unique characteristic makes them invaluable in applications where precise control of light shaping is necessary, such as in line generation for laser systems. By converting a collimated laser beam into a line, these lenses enable more efficient and targeted illumination, which is crucial in various optical systems.
The design of Plano-Concave Cylindrical Lenses involves a flat surface on one side and a concave curve on the other. This structure helps in diverging light beams efficiently. When using these lenses to diverge a beam, it is recommended that the curved surface faces the light source to minimize aberrations. This configuration ensures optimal performance and maintains the integrity of the light path, which is essential for high-precision tasks.
These lenses are available in a range of focal lengths from -5.0 to -1000.0 mm, with a tolerance of ±1%. The dimensions vary from 1.0 mm to 200.0 mm, and they are crafted to high-quality standards with scratch and dig specifications ranging from 80/50 to 40/20. Additionally, the center error is maintained between 5 arc minutes to 3 arc minutes, ensuring precise optical performance.
For enhanced durability and performance, Plano-Concave Cylindrical Lenses can be coated with MgF2 to protect their surfaces or with anti-reflective (AR) coatings to increase light transmission. These coatings are particularly beneficial in applications where maximizing light throughput and minimizing reflection losses are critical.
