OPTOLYTH® Eyepieces



Diversity leads to success

The right magnification for any distance

For any purpose, any eye, any magnification. The various interchangeable eyepieces let you adapt your fixed scope to the job at hand. The eyepieces on your fixed spotting scopes can be switched quickly and easily.


Eyepiece 20x WW

The 20xWW is highly suitable for counting birds on large expanses of water or to determine the size of an entire flock. The computer calculated wide angle lens (WW) makes a field of view of 54 metres possible and gives you the necessary overview for these tasks. For quick observations in between other tasks the scope can be used without a tripod at a 20x magnification – it’s enough to simply rest the scope on any surface.

Eyepiece 70x WW

Real professionals who need to be able to distinguish even the smallest detail sometimes choose this rather exotic magnification. It requires, however, quite some experience in handling spotting scopes and tripods, an indispensable tool when working with the 70xWW. This eyepiece frequently appeals to users in astronomy as well, where it can be used to gain a quick overview. Please note that this eyepiece was specifically designed to fit our 80 mm scopes.

Zoom-eyepiece 20-60x (80 mm) / 30-60x (100 mm)

The zoom eyepiece from OPTOLYTH® lets you handle each situation with the required flexibility. The variable magnification of between 20x and 60x offers the user images that are superbly true to detail at maximum resolution. No matter if your focus lies in gaining a quick overview or noticing the smallest difference, this eyepiece easily adapts to your personal needs. The most popular among OPTOLYTH®’s eyepieces renders diverging initial magnifications due to the differing focal lengths of the 80 mm and 100 mm scopes.
