36-726 25mm Dia x 40mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm

The 36-726 is a 25mm diameter, 40mm focal length plano-convex lens, designed for visible light applications with a wavelength of 587.6nm. Sourced from Edmund Optics, this lens boasts a high-quality fused silica material (fused sil mal-1965) known for its excellent transparency and resistance to thermal shock.

The lens features a standard antireflection coating on both the front and back surfaces, specifically the EDM VIS-0 coating, which is optimized for the visible light spectrum (425-675nm). This coating significantly reduces surface reflections, thereby increasing light transmission and improving overall system performance.

The plano-convex geometry of this lens, where one surface is flat and the other is curved, provides a number of benefits. It minimizes spherical aberration, a common issue in optical systems, and offers a large, flat field of view. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across its surface.

The lens's geometry also includes a 2.58mm edge thickness and a 7.5mm center thickness. The edge thickness is crucial for maintaining the lens's structural integrity, while the center thickness influences the lens's optical power. The back focal length (BFL) is 34.86mm, and the effective focal length (EFL) is 40mm, which are important parameters for designing and integrating this lens into optical systems.
