66-332 30 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=30mm; NA=0.5 BBAR 600-1050nm
The 66-332 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 0.5, making it suitable for a wide range of optical applications.
The lens is made from L-BAL35, a material from Ohara's comprehensive catalog of optical glass. This material is known for its excellent transmittance in the near-infrared region, making the lens ideal for use in applications where light in this region is prevalent.
The lens's geometry is carefully crafted, with an inner radius of 0mm and an outer radius of 0mm. The effective focal length (EFL) is 30mm, and the back focal length (BFL) is 22.99mm. The lens has a center thickness of 11.7mm and an edge thickness of 4.81mm, providing robustness and durability.
The 66-332 lens features a BBAR coating on both the front and back surfaces, enhancing its performance in the 600-1050nm wavelength range. This coating reduces reflection, thereby increasing the amount of light transmitted through the lens, and improving overall system efficiency.
