66-335 50 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=37.5mm; NA=0.66 BBAR 600-1050nm
The 66-335 is a high-precision aspheric lens offered by Edmund Optics, boasting a 50 mm diameter and a numerical aperture of 0.66. This lens is designed for use in the near-infrared spectrum, with a wavelength of 587.6 nm.
The lens is constructed from L-BAL35, a material specifically engineered by Ohara for exceptional optical performance. The aspheric design of the lens helps to minimize spherical aberration, delivering sharp, clear images even at wide apertures.
The lens features a effective focal length (EFL) of 37.5 mm, making it suitable for a variety of optical applications. The front and back surfaces of the lens are coated with BBAR 600-1050, a broadband anti-reflection coating that enhances transmission in the 600-1050 nm range.
The lens has a thickness of 3.23 mm at the edge and 19.4 mm at the center. The inner and outer radii are 0, and the front and back focal lengths are 0 and 25.74 mm, respectively. The lens's shape is defined by its conic constant (k1) of -0.632106.
