89-044 20.0mm Dia. x 70.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm

This is a 20.0mm diameter, plano-convex lens with a focal length of 70.0mm, specifically designed for use with a wavelength of 1064nm. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The plano-convex geometry, where one side is flat and the other curved, is ideal for a variety of applications, particularly where a collimated beam is required.

The lens features a laser V-coat coating on both the front and back surfaces. This coating is specifically designed for use with 1064nm lasers, enhancing the lens's performance and durability in such environments. The coating ensures high transmission and low reflection at the specified wavelength, making it ideal for laser applications.

The lens has a thickness of 1.59mm at the edge and 3mm at the center. The inner and outer radii are not specified, indicating that the lens is a simple plano-convex design. The back focal length (BFL) is 68.03mm, and the effective focal length (EFL) is 70mm.

The item data also indicates that this lens is in stock, making it readily available for immediate use. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
