LP11-38-300 38 mm Dia. N-BK7 Plano-Concave Lens; EFL=-300mm Uncoated
The LP11-38-300 is a 38 mm diameter Plano-Concave Spherical Lens, sourced from CeNing Optics. This lens is designed for use in optical systems that require negative focal lengths, with an effective focal length (EFL) of -300mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transmission range. The lens has a center thickness of 2mm, providing a robust and stable platform for optical systems.
The LP11-38-300 is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where the user does not require additional coatings, or where cost is a significant factor.
The lens's geometry is defined by its inner and outer radii. In this case, the inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface. The concave surface has a radius of -155.6mm.
This lens is designed for use at a wavelength of 546.1nm. It is important to note that the performance of the lens can vary depending on the wavelength of light used.
