LD4269-UV 12.7 mm Dia. UVFS Double-Concave Lens; EFL=-30.1mm 245-400nm

The LD4269-UV is a high-quality spherical lens from Thorlabs, designed for use in ultraviolet (UV) applications. This double-concave lens features a diameter of 12.7 mm and a center thickness of 3 mm, making it a compact and efficient option for a variety of setups.

The lens has an effective focal length (EFL) of -30.1 mm, which is a key factor in determining its optical properties. This negative EFL indicates that the lens is a diverging lens, meaning it spreads out light rays that pass through it. This can be useful in a variety of applications where light needs to be spread out over a larger area.

The LD4269-UV is made from UVFS, a material specifically designed for use in the UV spectrum. It has a wavelength of 588 nm, which falls within the UV range. The lens is coated with THo UVFS UV BAR on both the front and back surfaces, which enhances its performance in UV applications.

This lens is part of Thorlabs' extensive catalog of optical elements, and it is currently in stock on their website. The link to the product page is provided for your convenience. With its high-quality construction, specific UV design, and excellent optical properties, the LD4269-UV is an excellent choice for any UV optical setup.
