67-253 30 mm Dia. N-SF5 Precision Aspheric Lens; EFL=17.5mm; NA=0.86 BBAR 425-675nm
This is the 67-253 model from Edmund Optics, a high-precision aspheric lens with a 30 mm diameter and a numerical aperture of 0.86. The lens is made from N-SF5 Schott, a high-refractive index glass, and features broadband anti-reflection (BBAR) coating for the 425-675nm wavelength range.
The lens has an effective focal length (EFL) of 17.5mm, making it suitable for applications that require a long focal length in a compact package. The aspheric design helps to reduce spherical aberration, improving the overall image quality. The lens has a center thickness of 13.5mm and an edge thickness of 1.78mm, providing structural rigidity and resistance to deformation.
The BBAR coating on both the front and back surfaces of the lens reduces reflective losses, enhancing the transmission of light. This is particularly beneficial in applications where high light throughput is required, such as in imaging systems, beam shaping, and laser applications.
The 67-253 model is currently in stock and available for immediate shipping. For more information, please refer to the vendor's website or contact their customer service.
