Volk & Ocular Lenses
Volk lens used with a slit lamp, a bright focal source of light with a slit of variable width and height A useful list of the most common slit-lamp condensing (Volk) lenses and their associated magnification factors.
Display: List / Grid
The Volk Area Centralis Lens is excellent for critically evaluating and treating sub-retinal neovascularisation and changes from macular degeneration, retinal vascular occlusions, diabetic macular edema, proliferative diabetic retinopathy and other r..
The Volk Digital 1.0x Imaging Lens has unique glass surface curves and coatings optimised for the visible spectrum to reduce glare and reflections during general diagnosis and slit lamp photography. This lens provides a high resolution view of t..
The double aspheric glass optics of this Volk lens provide enhanced imaging and the low dispersion glass reduces chromatic aberration for extremely high resolution retinal imaging. High magnification provides topographical views of the nerve fibre la..
The Volk Digital Wide Field Lens combines exceptional wide field views and magnification. The enhanced double aspheric design and multi layer coating provide high resolution stereo views of the retina through a small pupil, with minimal reflecti..
The Four Mirror Gonio Volk Lens features four precisely angled 64 degree mirrors to deliver complete view of the anterior chamber with slight rotation. This standard fluid design (flanged glass contact element) provides a stable platform during laser..
Designed specifically for Selective Laser Trabeculoplasty. 1.0x magnification maintains laser spot size for accurate laser energy delivery. Tilted anterior lens surface corrects astigmatism to maintain circular laser beam profile and give shar..
The Two Mirror Magna View gives unsurpassed image resolution and magnification of the anterior chamber angle. The 1.45x gonio magnification provides fine detailed viewing of the anterior chamber angle structures. The second mirror reduces the ..
Four mirrors plus a central axis view give a complete view of the interior of the eye. Unique "depth dots" mark each mirror at the base for easy orientation. One dot, 62° (anterior chamber angle); two dots, 67° (ora serrata); three dots, 76° ..
The 130 degree Quadraspheric Volk Lens has grown in popularity since its introduction in 1989 as the preferred wide field fundus laser lens. Its sleek 28.6 mm diameter housing provides a definite advantage over competitive wide field lenses for ..
This lens positioning instrument mounts directly on the slit lamp allowing your Volk lens to be universally positioned, tilted and angled with accuracy and ease for both left and right eye fundus viewing. Excellent for routine examinations as well as..
This stereo fundus volk lens is specifically designed for high resolution/high magnification viewing of the central retina. Its enhanced 3D stereoscopic design enables discernment of subtle macular and optic disc detail, making it ideal for dete..
The Superfield NC Volk Lens has become the standard for slit lamp fundus diagnosis by today's discriminating practitioner. It's 0.76x magnification and wide field of view make it perfect as the primary high resolution slit lamp fundus diagnostic..
The Superpupil XL NC Volk lens provides the widest pan equatorial fundus view of any non-contact lens available, with over a 100 degree field visible in a single view. The wide field/high resolution optics allow detailed inspection of the poster..
This Volk Gonio lens incorporates 3 mirrors angled at 60, 66 and 76 degrees and is ideal for anterior chamber as well as central and peripheral fundus viewing and treatment. The retinal viewing mirrors are accurately angled and spaced to eliminate "g..
The Transequator Volk Lens is designed for focal laser therapy and mid-to-far peripheral fundus diagnosis. Its unique optical design presents a realistic contour of the retinal concavity, offering an impressive wide-field view of the entire posterior..
This lens is perfectly corrected for field curvature, astigmatic aberrations and coma - delivering the best retinal image of any 20 dioptre lens on the market. Its advanced double Aspheric design further maintains linear image magnification and perfe..
This excellent mid-power lens provides median field magnification, with an ideal diameter for grip and manipulation within the orbital area. Field of view: 52/68 degrees Image magnification: 2.54x Working distance: 38mm Primary applicatio..
This lens provides exceptional resolution and fundus scanning capabilities. Excellent for small pupil diagnosis and treatment. Field of view: 53/69 degrees Image magnification: 2.27x Working distance: 33 mm Primary application: Smal..
This lens is designed to provide the practitioner with a wide field of view with a shorter working distance and is excellent for use with small pupils. Field of view: 58/75 degrees Image magnification: 2.15x Working distance: 30 mm Primar..
The 60D lens provides the highest magnification of the non-contact slit lamp lenses and is ideal for detailed disc and macular viewing. The 31mm ring diameter facilitates easy handling within the orbital area. Field of view: 68/81 degre..
This double aspheric 78D lens is an excellent general diagnostic and laser treatment lens offering an ideal 0.93x image magnification and wide 97 degree dynamic field of view. It is optimally designed for use within the range of motion of all sl..
This lens features a small 26 mm diameter ring design which is outstanding for dynamic fundoscopy. Its double aspheric optical design expands the usable viewing field beyond that of competitive designs. This lens has good small pupil capabilities, ma..
The Pan Retinal 2.2 Volk Lens combines magnification similar to that of the 20D lens with a field of view approaching that of the 30D lens. Ideal for almost all examination procedures, including small pupil examinations. Field of v..
