LA1978-YAG N-BK7 Plano-Convex Lens; Dia:1 in; f=750.0 mm YAG V-Coat 532/1064nm

This LA1978-YAG N-BK7 Plano-Convex Lens, sourced from Thorlabs, is a high-quality optical component designed for a wide range of applications. The lens features a plano-convex geometry, which means one side is flat (plano), and the other side is curved (convex). This design is particularly useful in focusing or collimating light beams.

The lens has a diameter of 1 inch (25.4 mm) and a center thickness of 2.2 mm, ensuring robustness and durability. The edge thickness is 2 mm, providing additional strength and resistance to edge chipping. The effective focal length (EFL) of this lens is 750 mm, which is the distance from the lens center to the focal point when the lens is imaging an object at infinity.

The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transmission range. The lens's inner and outer radii are 0, indicating a sharp curvature on the convex side.

The lens is coated with a YAG V-Coat, designed for 532/1064 nm. This coating enhances the lens's performance by reducing reflection and increasing transmission at these wavelengths. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
