G-lens
GRIN lenses, also known as gradient-index lenses, are cylindrical optical lenses whose refractive index varies gradually along the radial direction, with focusing and imaging functions. With end-face collimation, coupling and imaging characteristics plus a compact cylindrical shape, they are convenient for use in various micro optical systems. The official website gives ordering specifications in a coding table of diameter/wavelength/angle/pitch/coating/bandwidth.
