The aspherical surface corrects the deviations that occur in simpler, spherical lenses, thus helping to improve the field of view for diagnostics. Volk dual aspherical loupes provide linear magnification of the image, providing a better overall image.
Dioptric Power
Ophthalmoscopic loupes with a higher dioptric power provide a smaller field of view and higher magnification, which provides the best performance in animals with small pupils. Ophthalmoscopic loupes with a lower dioptric power have a larger field of view and lower magnification, so they are well suited for animals with larger pupils. Direction of the loupe
Dual aspherical loupes are not always symmetrical. Depending on which side of the loupe you look through, a loupe with asymmetric aspheres will give different optical results. The letter "V" resembles an arrow and is directed toward the patient. Some loupes have a silver border on one side, which should always be directed toward the patient. Features
Combines the advantages of a 20D magnifier with a larger field of view and higher image resolution, as well as minimal reflection thanks to special glass.
