32-995 25mm Dia. x -100mm FL; MgF2 Coated; Double-Concave Lens 400-700nm

This is a 25mm diameter, double-concave lens with a focal length of -100mm, making it a powerful tool for a variety of optical applications. The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties.

The lens features a front and back coating of MgF2, a material known for its low refractive index and high transmission in the visible spectrum. This coating helps to reduce surface reflections, improving the overall efficiency and quality of the lens.

The lens is designed for use in the 400-700nm wavelength range, making it suitable for a wide range of applications, including but not limited to, fluorescence microscopy, spectroscopy, and laser systems.

The geometry of the lens includes an inner radius of 0 and an outer radius of 0, with a thickness at the edge of 6.43mm and a thickness at the center of 5mm. This gives the lens a robust and durable construction, while also maintaining a high level of optical performance.

The lens is sourced from Edmund Optics, a leading manufacturer of optical components, ensuring a high level of quality and reliability. The lens is currently in stock, ready for immediate dispatch.
