This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa. The lens has a base shape of a circle and is designed for use in various optical systems. The lens is made from the material n-bk7 schott, a common choice in the industry due to its excellent optical properties.
The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm. The thickness at the center is 3 mm, providing a solid structure for various applications. The effective focal length (EFL) of this lens is 150 mm, a long focal length that can be used in various applications requiring a narrow field of view or high magnification.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in certain applications where the natural properties of the lens material are desired. However, it may also mean that the lens is more susceptible to environmental factors such as dust, dirt, and moisture.
The lens's geometry is defined by its inner and outer radii, both of which are 0 in this case. This indicates that the lens is a simple plano-convex design, with one flat surface and one curved surface. The curvature of the curved surface is defined by a radius of 77.505 mm.
This lens is designed to work with light of a wavelength of 546 nm. This wavelength falls within the visible light spectrum, making this lens suitable for use in various applications involving visible light.
