HO-BVL50-03B 50mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm BBAR 400-700nm
This is a HO-BVL50-03B 50mm diameter N-BK7 double-concave lens, featuring an effective focal length (EFL) of -150mm and broadband anti-reflection (BBAR) coating for the 400-700nm wavelength range. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for its high-quality optical components.
The lens is a spherical type, with a base shape of a circle. Its geometry includes a 50mm diameter, a 2.5mm center thickness, and radii of curvature of -157.589616mm for the first surface and 157.589616mm for the second surface. The lens does not have an inner or outer radius.
The lens material is N-BK7, a popular choice for optical applications due to its excellent optical properties. The BBAR coating on both the front and back surfaces enhances the lens' performance by minimizing surface reflections, thereby increasing transmission in the specified wavelength range.
The lens's EFL of -150mm indicates that it is a diverging lens, which spreads out light rays. This can be useful in various applications, such as beam expansion or image reduction.
