L-PCC032 18 mm Dia. Plano-Concave Lens; EFL=-29mm Uncoated
The L-PCC032 is a plano-concave lens with a diameter of 18 mm, making it suitable for applications requiring a compact optical component. The lens features a center thickness of 2 mm and an effective focal length (EFL) of -29 mm, indicating its diverging nature. This type of lens is often used in applications where beam expansion or divergence is required.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The refractive index of this material at the specified wavelength of 587.6 nm is 1.5168, which contributes to the lens's optical performance.
Notably, the lens is uncoated. While coatings can enhance the performance of lenses by reducing surface reflections, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
This lens is sourced from Ross Optical, a reputable vendor known for their extensive catalog of optical elements. The vendor's website indicates that the lens is in stock, ensuring prompt delivery for your optical project needs.
