LP11-25-200 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm Uncoated
This is a Plano-Concave Spherical Lens, sourced from CeNing Optics, with a diameter of 25.4 mm and a center thickness of 2 mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and wide transparency range.
The lens has a negative focal length (EFL) of -200mm, making it suitable for applications that require light to be diverged or spread out, such as in collimators or beam expanders. The inner and outer radii are 0, indicating a plano-concave geometry, where one surface is flat and the other is curved inward.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This might make it more susceptible to environmental factors like dust, moisture, or scratches, but it also means that it can be easily integrated into various systems without worrying about coating compatibility.
