The Zeiss DiaScope Vario 15-45x/20-60x Eyepiece provides variable magnification to enhance the viewing capabilities of the Zeiss Victory DiaScope spotting scope. With a 65 mm DiaScope this ocular offers 15-45x magnification and a 3.2-1.5° FOV. When it’s installed upon an 85 mm DiaScope, the magnification is 20-60x with a 2.5-1.2° FOV.
Optically, the Vario 15-45x/20-60x eyepiece has been engineered to match the performance of the DiaScope T* FL spotters. Achromatic fluoride-glass lenses have been implemented for their exceedingly high level of visual acuity and accurate color rendition. The exterior lens surfaces have been graced with a protective LotuTec coating that sheds water, mist, fog, and oils. By minimizing the presence of these image-dispersing contaminants, the LotuTec coating maximizes the lens’ optical qualities. Every air-to-glass surface of each lens has been fully multicoated with Zeiss’ proprietary and legendary T* coating to ensure optimum light transmission, contrast, and color fidelity.
A simple yet robust bayonet mount ensures a secure fit to the DiaScope’s housing - a simple twist-to-attach operation puts the ocular into its working position. Eye/sunglass wearers will greatly appreciate the eyepiece’s generous 16 mm of eye relief along with the adjustable twist-up rubber eyecup.
