34-165 25mm Dia. x 75mm FL UV Plano-Convex Lens Laser V-Coat 1550nm

The 34-165 is a 25mm diameter, plano-convex lens designed for use with a 1550nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. The lens features a fused silica material (fused sil mal-1965) which is renowned for its excellent transmission properties and chemical resistance.

The lens has a 75mm focal length (FL), making it suitable for a wide range of applications that require moderate magnification. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a 2.08mm edge thickness and a 4.43mm center thickness, providing robustness and stability.

The 34-156 lens is coated with Edmund Optics' Laser V-Coat, designed specifically for 1550nm. This coating enhances the lens' performance by reducing surface reflections and improving transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
