Volk Research Lenses provide high resolution views of the posterior pole and anterior chamber angle structures, as well as views of the optic nerve and posterior retina. With their small contact surfaces, these lenses do not require viscous coupling fluid. Available Research Lenses Include: 2mm Fundus Lens 2mm Gonio Lens 2mm Fundus Lens High resolution view of the posterior pole AR coating minimizes glare and reflections, while maximizing laser throughput Conically shaped contact surface No need for viscous coupling fluid Fixed handle angle of 45° 2mm Gonio Lens High resolution view of anterior chamber angle structures View the optic nerve and posterior retina through the center of the lens 4 equally angled mirrors Small contact surface No requirement of viscous coupling fluid Handle can be fixed either straight or at a 45° angle
