Eyepiece protector with protective glass for eyepieces that are compatible with the TSN-99/88/880/770 series spotting scopes. TE-11WZ / TE-80XW as well as with the TE-10Z (20-60x zoom eyepiece) and TE-17W (30x wide-angle eyepiece), which are no longer available. The eyepiece protector has a twist-up function which allows the exit pupil distance to be individually adjusted. The rear end of a spotting scope is also vulnerable. Just like the front lens, the eyepiece is often exposed to the risk of damage. The eyepiece lens or its coating can also be scratched by adverse conditions, but also by the user. This can be caused by improper handling or lack of protection during storage or transportation. Just like the condition of the objective lens, the condition of the eyepiece is also decisive for the performance of a spotting scope. Repairs caused by damage are usually very expensive due to the amount of work required. All you need to do is unscrew the eyecup on the eyepiece and replace it with this eyepiece protector. The eyepiece protector consists of a rubber eyecup which is also fitted with a protective glass. This provides the eyepiece lens with optimum protection against possible scratches and damage.
