Inimitable — how this hummingbird excitedly whirrs around the blossoms. Phenomenal — to move through the galaxy of stars as if you were on board a spaceship.

 

Breath-taking — how a formula one pilot still manages to win the race on the last couple of metres … ASPECTEM observation binoculars set new limits between the definition of merely watching and feeling the action.

  • Sturdy and splash-proof
  • Climate-resistant
  • Versatile
  • Unique optical performance

 

 

At first glance, the aluminium die cast body reveals binoculars manufactured in a high-quality and sturdy manner.The use of high-quality lenses and a special multi-coating of all glass/air surfaces additionally guarantee highest optical standards as far as brilliance and image quality are concerned.

To set the correct eye relief it is only necessary to move one side of the prism housing. A sophisticated coupling likewise moves the opposite housing.

Flat knurled clamping rings facilitate an easy setting of the desired attenuation and locking for both swivelling axes.

Furthermore, the line of sight integrated in the carrying handle makes it possible to conveniently preset the ASPECTEM to far away targets.

With its medium magnification, its large field of vision and its suitability for spectacle wearers, the standard eyepiece is an all-purpose eyepiece.

The standard eyepiece is the economic alternative within the ASPECTEM range of eyepieces.

DOCTER offers as "standard" what others describe as "wide angle"!

Enjoy the possibility of gradually changing the magnification of your ASPECTEM.

This offers you a choice between a large field of vision or a particularly large magnification, thus enabling you to optimally combine a panoramic view with detail magnification.

Thanks to its special patented design, this eyepiece is one of the few variable eyepieces where the subjective field of vision is to a large extent independent of the set magnification.

The DOCTER® Vario eyepiece does not present you with a keyhole view. The low magnification offers you the necessary overview to locate details and to get your bearings, while the large magnification provides a good resolution for interesting details.

 

By changing the focal distance of the eyepiece and thus also the magnification and the size of the exit pupil, it is possible to optimally adjust the binoculars to varying observation conditions during the day or night and also to visibility conditions.

In most cases, no subsequent zooming-in is necessary when the magnification is changed.

We are the only manufacturer to offer variable eyepieces in observation binoculars.

This ultra wide angle eyepiece is a newly developed state-of-the-art eyepiece, superseding the reliable and highly commended 90° eyepiece.

With its aid it is possible to overview an enormous field of vision, at the same time enjoying a large magnification. Apart from the unparalleled panoramic impression, it is characterised by an exceedingly good ease of view and suitability for spectacle wearers.

The image is crisp and clear up to the margin. This is achieved with the unique optical design, integrating modern lens engineering features in the eyepiece.

In addition, the UWA eyepiece is available in a special design as slide-on eyepiece for astronomical applications.

The appeal of the ultra wide angle anastigmatic eyepiece lies in its stigmatic (stigma=dot) imaging across the entire field of vision. Even stars at the image margin are still point-shaped and visible as an incomparably clear image.

This characteristic and highest transmission values are ensured by the use of special lenses produced by leading lens manufacturers.

 

Compared to the precursor model, it was possible to reduce the distortion without having to cut back on the actual field of vision. Thus, the field of vision is still clear during relaxed viewing and invites to longer observation sessions.

This is additionally supported by the large eye relief, which by folding back the eyecup even facilitates observations wearing spectacles.

In addition, the rubber eyecup cushions the transmission of disturbing vibrations to the system.
