Teleloupe Spectacles G 2.5 TTL

The G 2.5 TTL teleloupe spectacles are head-worn binocular loupes that are fitted individually by eyecare professionals. They are used for binocular, stereoscopic near vision by professional users, e.g. in medicine and technology.

The Galilean-type teleloupe systems offer 2.5x magnification and are available in three different working distances. The optical systems are mounted in the carrier lens (TTL = through the lens).

Either the proven system carrier STMS or a fashionable sports frame can be used as a system carrier. For maximum comfort, the system carrier is equipped with sides and a strap.

The plastic carrier lenses of the STMS system carrier can be with or without prescription. If required, the eyepieces of the optical systems combined with STMS can also contain prescription power.

For the sports frame, a clip-on for prescription lenses is available to be fitted instead of the nose pads.

Please mind the respective production range. The G 2.5 TTL teleloupe spectacles can be combined with the Saphiro² LED illumination. This results in an ideal combination of magnification and illumination.

Notes on the ordering and fitting of the Teleloupe Spectacles G 2.5 TTL

The following data is required in the order for mounting of the optical systems in the carrier lenses:

  • 1. Single PD for distance. (The nasal inset for near is calculated by Carl Zeiss Vision as a function of the centering data.)
  • 2. Viewing height for distance
  • 3. Vertex distance (corneal vertex to front lens vertex)
  • 4. Working distance of the optical systems
  • 5. Prescription powers for the eyepieces of the optical systems if required
  • 6. Prescription powers of the carrier lenses/clip-on prescription lenses, if required
  • 7. System carrier (variant and size)
