33-960 15mm Dia. UVFS Aspheric Lens; EFL=25mm; NA=0.3 VIS 425-675nm

This is the 33-960 model from Edmund Optics, a 15mm diameter UV Fused Silica Aspheric Lens, designed for use within the visible light spectrum, specifically between 425-675nm. The lens boasts an effective focal length of 25mm and a numerical aperture of 0.3, making it suitable for a variety of optical applications.

The lens is made from high-quality UV Fused Silica, a material known for its excellent transmission properties across a wide range of wavelengths. This makes the lens particularly versatile, able to handle both ultraviolet and visible light with ease.

The aspheric design of the lens is a notable feature, offering superior optical performance compared to traditional spherical lenses. This is achieved through the precise shaping of the lens, which reduces spherical aberration and distortion, resulting in sharper images and more accurate light transmission.

The lens is coated with a Visible (VIS) coating, specifically designed for the 425-675nm range. This coating enhances the lens's performance by reducing surface reflections, thereby improving light transmission and reducing light loss.

The lens has a center thickness of 4.36mm and an edge thickness of 1.79mm, providing a robust and durable construction. The front and back surfaces of the lens are coated with the same VIS coating, ensuring optimal performance from both sides.
