LA4647-1064 12.7 mm Dia. UVFS Plano-Convex Lens; EFL=20mm 1064nm V-Coat
The LA4647-1064 is a plano-convex lens with a diameter of 12.7 mm, designed for use with a wavelength of 587.6 nm. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens is made from UVFS material with the Mal-1965 identification, ensuring durability and reliability.
The lens geometry is characterized by its edge thickness of 2 mm and center thickness of 4.3 mm. The effective focal length (EFL) is 20.1 mm, making it suitable for a wide range of optical applications. The lens has a spherical shape, with a radius of curvature (R1) of 9.2 mm for the curved face. The inner and outer radii are both 0 mm, indicating a uniform curvature.
The LA4647-1064 is coated with Thorlabs' V-AR-1064 coating on both the front and back surfaces. This coating is specifically designed for use with a 1064 nm wavelength, enhancing the lens' performance in this range. The coating helps to reduce reflection and increase transmission, making the lens more efficient in its function.
