Both sides of a biconcave lens are concave and have the same curvature radius. Double concave lenses with negative focal length are commonly used for beam collimation, increasing (decreasing) focal length, or enlarging (reducing) images. N-BK7 is the most common lens material
Introducing our Double Concave Spherical Lens, a versatile optical component designed for various applications such as beam expansion, collimation, projection, and focal length enlargement.
Crafted with precision and expertise, this lens offers exceptional performance and reliability in optical systems. Its double concave shape allows for the divergence of light rays, making it ideal for applications that require beam expansion or collimation.
With its ability to project and enlarge optical systems' focal lengths, this lens proves to be an indispensable tool in industries such as imaging, microscopy, and laser technology. Whether you need to enhance the beam diameter, achieve parallel light rays, or extend the focal length, our Double Concave Spherical Lens is the perfect solution.
Manufactured using high-quality materials, this lens ensures excellent optical clarity and minimal aberrations, resulting in crisp and accurate imaging. Its professional-grade construction guarantees long-lasting performance, making it suitable for both research and industrial applications.
Experience the precision and efficiency of our Double Concave Spherical Lens, a reliable choice for professionals seeking optimal beam control, collimation, and focal length adjustment.
