67-275 25mm Dia. UVFS Aspheric Lens; EFL=20mm; NA=0.63 VIS 425-675nm
The 67-275 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25mm, is constructed from HPFS7980 Corning, a material known for its exceptional optical properties. The lens is specifically designed for use within the visible light spectrum, between 425 and 675nm.
The lens boasts an effective focal length (EFL) of 20mm, making it suitable for a wide range of optical applications. The numerical aperture (NA) of this lens is 0.63, indicating a high light-gathering capability and a shallow depth of field. This makes it ideal for use in high-resolution imaging systems.
The lens features a unique aspheric design, with a first radius of curvature (R1) of 9.17mm and a second radius of curvature (R2) of 0mm. This design helps to minimize spherical aberration, coma, and other optical aberrations, resulting in superior image quality. The lens has a center thickness of 14mm and an edge thickness of 2.27mm, providing excellent structural integrity.
The 67-275 lens is coated with a broadband anti-reflection coating, specifically designed for the visible light spectrum (VIS 425-675nm). This coating reduces surface reflections, enhancing the transmission of light through the lens and improving overall system performance.
