Description
The Plano-Concave Lens is an essential component in optical systems, known for its distinctive design where the lens is thicker at the edges and thinner at the center. This unique structure, combined with its flat surface on one side, makes it an ideal choice for applications requiring the expansion of light beams or the increase of focal lengths. The lens is particularly effective in systems utilizing high peak power pulsed lasers, as it can efficiently manage and manipulate light paths.
When a beam of light encounters the concave surface of this lens, it is directed to a focal point outside the instrument, allowing for precise control over the beam's trajectory. This characteristic is crucial for various scientific and industrial applications where beam expansion and focal length adjustments are necessary for optimal performance.
Constructed from high-quality materials such as BK7, UV FS, and CaF2, the Plano-Concave Lens ensures exceptional durability and performance. Its surface flatness, measured at λ/10@632.8nm, and superior surface quality of 10/5, guarantee minimal aberrations and high precision in optical tasks. Furthermore, the lens is crafted with tight tolerances, including a diameter tolerance of +0.0/-0.05mm and a thickness tolerance of ±0.05mm, ensuring consistent and reliable results in demanding optical systems.
With a clear aperture exceeding 90% of its diameter, the Plano-Concave Lens maximizes light throughput, making it a versatile component in various optical configurations. The protective chamfering further enhances its durability, while the option for custom coatings allows for tailored solutions to meet specific customer requirements. This lens is an indispensable tool for professionals seeking precision and efficiency in their optical applications.
