17-004 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=22.5mm; NA=0.66 SWIR-Plus 900-1700nm
The 17-004 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 30mm diameter and a numerical aperture (NA) of 0.66, specifically designed for use in the shortwave infrared (SWIR) spectrum, between 900 and 1700nm.
The lens is made from N-SF5 Schott, a material known for its excellent transmission properties in the SWIR range. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, which can lead to distorted images. This makes the 17-004 an ideal choice for applications that require high resolution and accuracy, such as scientific research, machine vision, and medical imaging.
The lens has an effective focal length (EFL) of 22.5mm, which determines the distance between the lens and the image sensor to achieve a focused image. The lens also features a high thickness at the edge (6.62mm) and a center thickness of 15mm, providing structural rigidity and resistance to deformation.
The 17-004 is coated with Edmund Optics' SWIR-Plus coating, which is specifically designed for the 900-1700nm range. This coating enhances the lens's transmission capabilities, reducing light loss and improving overall image quality. The coating is applied to both the front and back surfaces of the lens.
