49-103 25 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=31.25mm; NA=0.4 BBAR 425-675nm
The 49-103 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 25 mm, is constructed from L-BAL35, a material specifically engineered by Ohara for exceptional optical performance.
The lens boasts a numerical aperture (NA) of 0.4, which is a measure of the light-gathering ability of the lens. A higher NA allows for greater light collection, making this lens ideal for applications that require high light transmission.
The lens's effective focal length (EFL) is 31.25mm, which is the distance over which the lens focuses light. This EFL, combined with the lens's diameter, allows for a wide field of view while maintaining a compact form factor.
The lens is coated with BBAR 425-675nm, a broadband anti-reflection coating that reduces surface reflections across the visible spectrum. This coating enhances the lens's light transmission, thereby improving the overall system performance.
The lens's geometry is defined by its inner and outer radii, thickness at the edge and center, and the radii of curvature of its surfaces. These parameters are carefully controlled during manufacturing to ensure the lens meets the stringent requirements of precision optics.
