The original Volk 90D lens started the slit lamp examination revolution! It features a small 26mm diameter ring design which is outstanding for dynamic fundoscopy. Volk's exclusive Double Aspheric optical design expands the usable viewing field beyond that of competitive designs. The Volk 90D has good small pupil capabilities, making it ideal for a quick look at the posterior pole.
Available with SupraCoat (argon/AR) or LaserPlus (diode) laser coating.
