The 63-480 15.0mm Dia. x 20.0mm FL is a plano-convex lens sourced from Edmund Optics. This lens, with a diameter of 15.0mm and a focal length of 20.0mm, is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens's geometry is characterized by a thickness of 1.52mm at the edge and 3.8mm at the center. The radius of curvature (R1) is 13.46mm, and the back focal length (BFL) is 17.74mm. The lens is made of n-SF5 Schott, a high-quality optical glass known for its excellent transmittance and low autofluorescence.
This lens is designed to work with a wavelength of 587.6nm, making it suitable for applications that require high precision and clarity in the yellow-green part of the spectrum. The lens's spherical shape ensures minimal distortion and high image quality.
Please note that the lens is uncoated, which means it may be more susceptible to environmental factors such as dust, moisture, and scratches. However, this also means that the lens does not have any additional layers that could potentially introduce chromatic aberration or other optical distortions.
