This is the PLCX-25.4-36.1-C, a Plano-Convex Laser Grade Spherical Lens, offered by CVI Laser Optics. The lens has a diameter of 25.4 mm and a center thickness of 4.5 mm, with an edge thickness of 2.2 mm. The lens's effective focal length (EFL) is 70 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens's curvature is defined by a radius of 36.1 mm on the convex side, with the concave side having an infinite radius, hence the term 'plano'.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may be suitable for applications where the light is already within the range of total internal reflection (TIR) for the lens material, or where the user prefers to apply their own coating.
The lens is in stock and more information about it can be found in the provided weblink. This lens is a part of our extensive catalog of optical elements, designed to provide users with a wide range of options for their optical systems.
