45-589 1.0mm Dia. x 1.0mm FL; Uncoated; Plano-Convex Lens

The 45-589 is a 1.0mm diameter, 1.0mm focal length Plano-Convex lens, sourced from the reputable optical components vendor, Edmund Optics. This uncoated lens boasts a base shape of a circle, with a thickness of 0.64mm at the edge and 0.8mm at the center, making it an ideal choice for applications requiring a compact, lightweight lens.

The lens's geometry is characterized by an effective focal length (EFL) of 1.0mm, a radius of curvature (R1) of 0.85mm, and a back focal length (BFL) of 0.57mm. The inner and outer radii are 0mm each, indicating a plano surface on one side and a curved surface on the other. This particular lens is made from the high-quality glass material, n-lasf9 schott, and is designed to work optimally with a wavelength of 587.6nm.

The Plano-Convex lens shape is a common choice in various applications due to its simplicity and versatility. The convex surface refracts and focuses light, while the plano surface allows for easy coupling with other optical components. This lens is offered without any coating, providing users with the bare glass substrate, which may be suitable for applications where coating is not required or preferred.
