Need to purchase this item?
The LD1613-A by ThorLabs is an exceptional bi-concave lens that is utilized for precise optical applications. Made from high-quality N-BK7 substrate, the LD1613-A features a negative focal length of -100.0 mm and a spherical surface irregularity of λ/4, delivering unparalleled accuracy in beam manipulation.
The LD1613-A comes equipped with a broadband antireflection (AR) coating, deposited on both sides of the lens, specifically designed to reduce the amount of light reflected from its surface. This coating is ideal for the 350 nm - 700 nm range, providing superior performance in a wide range of applications. The LD1613-A can diverge a collimated beam to a virtual focus, much like a Galilean-type beam expander. Furthermore, this lens is best suited for applications where a plano-concave lens would typically be used. This lens offers higher dispersion compared to its N-BK7 counterparts due to its lower Abbe Number, making it a versatile solution for precision optical applications.
