HO-PVL12.5-2.4B 12.5mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm BBAR 400-700nm
This is a Plano-Concave Spherical Lens, sourced from Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. The lens has a diameter of 12.5mm and a center thickness of 2.5mm, making it a compact and efficient optical component.
The lens's focal length (EFL) is -30mm, indicating that it is a diverging lens, which spreads out light rays. This can be useful in various applications where beam expansion is required.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties and wide transparency range. The glass type is identified as "n-bk7 schott" in the item data, suggesting that it is a high-quality Schott glass.
The lens features Broadband Anti-Reflection (BBAR) coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission across the spectral range of 400-700nm. This makes the lens ideal for use in applications where high transmission and low loss are critical, such as in imaging systems, beam delivery systems, and laser applications.
