67-259 25 mm Dia. N-SF5 Precision Aspheric Lens; EFL=15mm; NA=0.83 BBAR 600-1050nm

This is a high-quality 25 mm diameter aspheric lens, catalog number 67-259, offered by Edmund Optics. The lens boasts an impressive numerical aperture (NA) of 0.83, indicating its ability to gather and focus light efficiently. The lens is made from N-SF5 Schott, a material known for its excellent optical properties, particularly in the near-infrared region.

The lens has an effective focal length (EFL) of 15mm, making it suitable for a variety of applications where compact, high-performance optics are required. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.

The lens features broadband anti-reflection (BBAR) coatings, specifically designed for the 600-1050nm wavelength range. This coating helps to minimize surface reflections, thereby increasing the amount of light transmitted through the lens. The coating also helps to reduce ghosting and flare, further enhancing the overall image quality.

The lens has a thickness of 1.64mm at the edge and 11mm at the center. The front and back surfaces of the lens are coated with the same BBAR coating, ensuring optimal performance from both sides.

This lens is available for purchase directly from the Edmund Optics website, and as of the time of data collection, it is in stock. For more detailed information, including technical drawings and performance data, please refer to the product webpage linked in the item data.
