22-936 15mm Dia. N-SF6 Precision NIR Aspheric Lens; EFL=15mm; NA=0.5 Laser V-Coat 1550nm
This is a high-precision NIR (Near-InfraRed) Aspheric Lens, model number 22-936, manufactured by the renowned optical vendor, Edmund Optics. The lens is designed for use with a wavelength of 1550nm and features a laser V-coat, ensuring optimal performance and durability.
The lens is constructed from N-SF6 Schott, a high-quality optical glass known for its excellent transmission properties in the NIR spectrum. The lens has a base shape of a circle, with a diameter of 15mm, making it suitable for a wide range of optical applications.
The lens geometry is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 2.45mm. The Effective Focal Length (EFL) is 15mm, and the numerical aperture (NA) is 0.5. The lens features a precise aspheric surface, with a conic constant of -1.009, ensuring superior image quality and minimal distortion.
The lens is coated with Edmund Optics' proprietary laser V-coat, designed specifically for 1550nm. This coating ensures high transmission and low reflection, making it ideal for use in laser applications. The coating is applied to both the front and back surfaces of the lens.
