This is the PLCC-15.0-77.3-UV, a Plano-Concave Spherical Lens with a 15 mm diameter, sourced from CVI Laser Optics. The lens is designed for use with a wavelength of 588 nm and is uncoated.
The lens's geometry is characterized by its center thickness of 2.3 mm, a focal length (EFL) of -150 mm, and a radius of curvature (R1) of -77.3 mm. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a concave surface on the other.
The material of the lens is UVFS, specifically identified as UVFS MAL-1965 in the item data. This material is suitable for use in laser applications, as indicated by the item's "Laser Grade" designation.
The lens is uncoated, meaning it does not have any additional layers applied to its surfaces to alter its optical properties. This can be beneficial in certain applications where a specific coating is not required or desired.
The item data also indicates that this lens is in stock and available for immediate purchase. The vendor's website provides a detailed PDF with more information about this lens and other similar optical elements.
