PLCX-FS28 38 mm Dia. x 500 mm FL; Uncoated; Double-Concave Lens
The PLCX-FS28 is a high-precision double-concave lens, measuring 38 mm in diameter and offering a focal length of 500 mm. Manufactured by WTS Photonics, this lens boasts a base shape of a circle and is constructed from fused silica (Mal-1965) material, ensuring high-quality performance and durability.
The lens features a double-concave geometry, with radii of curvature R1 and R2 set at -230.1 mm and 230.1 mm, respectively. This configuration results in an effective focal length (EFL) of -500 mm and a back focal length (BFL) of 497.54 mm. The edge thickness of the lens measures 3 mm, while the center thickness is 3.79 mm, providing a well-balanced structure for various applications.
The PLCX-FS28 lens does not come with any coating, offering a bare, uncoated surface. This may be suitable for applications where coating is not required or preferred. The lens is currently in stock and available for immediate purchase through the provided weblink.
