HO-PVL25-1.2 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm Uncoated
This is a Plano-Concave Lens from Holmarc Opto-Mechatronics, with a diameter of 25mm and a center thickness of 2.5mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The effective focal length (EFL) of this lens is -30mm, making it a diverging lens that spreads out light rays.
The lens's geometry is defined by its inner and outer radii, which are both 0 in this case, and its first radius of curvature (R1), which is -15.648mm. This specific curvature contributes to the lens's diverging properties. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance or protect it from environmental factors.
This lens is suitable for applications that require light divergence, such as in imaging systems, beam expanders, or other optical instruments. However, due to its uncoated nature, it may not perform optimally in high-intensity light applications or environments with high humidity or temperature fluctuations.
