LUK-25.0-70.4-UV 25 mm Dia. UVFS Image Grade Plano-Concave Lens; EFL=-150mm Uncoated

The LUK-25.0-70.4-UV is a high-quality Spherical Lens (Plano-Concave) with a diameter of 25 mm, sourced from the reputable vendor CVI Laser Optics. This lens is designed for use in the ultraviolet spectrum, specifically at a wavelength of 404.7 nm.

The lens features a significant negative focal length (EFL) of -150 mm, making it suitable for applications that require strong converging or diverging light. The plano-concave design, where one surface is flat and the other is curved, contributes to its light-bending properties.

The lens is made from UVFS material, identified as MAL-1965 in the material database. This material is known for its transparency in the UV spectrum, ensuring optimal light transmission in its designated wavelength range.

Notably, this lens is uncoated. While coatings can enhance certain optical properties, such as reducing reflectance or increasing durability, an uncoated lens can offer advantages in specific applications, such as cost-effectiveness or simplicity.

The lens's geometry includes a center thickness of 5 mm, with both the inner and outer radii being zero. This suggests a symmetrical design, which can be beneficial for certain optical systems.
