Unlike conventional optical glass, with its abnormal partial dispersion properties, Gadron boasts a refractive index (nd) of 1.56907 nd, with an Abbe number (vd) of 7l.3. As a result, Gadron has extremely high abnormal dispensability in both the red and blue regions
Features: Can be molded with excellent polishing properties, chemical resistance, and transmittance
Applications: Correction of chromatic and spherical aberrations, removal of secondary spectra in the red and blue regions
