84-222 9.0mm Dia. x 18.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm

This is a 9.0mm diameter, plano-convex lens with a focal length of 18.0mm, specifically designed for use with a 1550nm wavelength. 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 wide transparency range. The plano-convex geometry, where one side is flat and the other is curved, is ideal for collimating or focusing light. The lens has a center thickness of 2.41mm and an edge thickness of 1.25mm, providing a good balance between weight and optical performance.

The lens features a laser V-coat coating on both the front and back surfaces. This coating is specifically designed for use with 1550nm lasers, ensuring high transmission and low reflection. The coating also provides excellent environmental stability, ensuring the lens maintains its performance over time.

The lens has a spherical shape, with a radius of curvature of 9.32mm on the curved side. This shape is ideal for general-purpose optical systems, providing a good compromise between complexity and performance. The lens also has a large clear aperture, allowing it to handle high optical power without significant deterioration in performance.
