38-629 25.4mm Dia. x 200mm FL; Uncoated; Laser Grade PCX Lens
The 38-629 is a 25.4mm diameter, 200mm focal length plano-convex spherical lens, sourced from Edmund Optics. This uncoated lens is designed for laser grade applications, making it an ideal choice for high-precision optical systems.
The lens's geometry includes a 3.08mm edge thickness and a 4mm center thickness, ensuring structural integrity and minimal distortion. The base shape is circular, providing a wide field of view and uniform illumination. The effective focal length (EFL) is 200mm, which, combined with the lens's diameter, offers a substantial light-gathering capability.
The lens is made from UVFS Mal-1965, a material known for its excellent optical properties and resistance to environmental factors. The wavelength of 587.6nm suggests this lens is designed for use in the visible light spectrum.
Notably, this lens is uncoated, which may be advantageous in certain applications where a specific reflection or transmission profile is required. However, for applications where high transmission and low reflection are critical, a coated version of this lens may be more suitable.
