Description

This is an extremely high quality 2x barlow lens, made in Jena, Germany, by Carl Zeiss. The Carl Zeiss Abbe Barlow lens consists of two parts:

  • A front barlow section ending with a photographic T-2 thread suitable to directly connect onto standard DSLR T-rings.
  • A T-2 photo thread with a Baader ClickLock eyepiece clamp with the known rotary clamping locking system (direct T-2 adaptation is possible).

On the first T-2 thread you can connect normal T-rings, so you have a 2x Barlow lens - with 1¼ " barrel - in front of a CCD/CMOS camera, webcam or a DSLR.

With this barlow, an image amplification up to three times (3x) is possible without any loss of quality by adding T-2 extension tubes. Baader recommend using their T-2 Varilock clamps for stepless adjusting of the optical length: Varilock 20-29mm (# 2956929) or Varilock 29-46mm (# 2956946)

Zeiss Abbe 2x Barlow Lens in 3x configuration with Vario Extension Tube

Example 3x set up with 2" BBHS Prism and the 29-46mm T-2 Varilock, 2" to 1.25" ClickLock reducer and 17.5mm Baader Morpheus eyepiece.

Optical Performance

This (german) document attests to the exceptional performance of the multi-layer anti-reflection coating applied onto the new 2016 Carl Zeiss Abbe-Barlow-Lens made in Jena / Germany. Carl Zeiss has chosen to develop and apply the very best coating ever made available to the most discriminating visual observer. The coatings feature a 0.2% loss over the exact spectral region where the night-adapted human eye is most sensitive. This extremely high efficiency also translates to near-zero coating scatter for the highest contrast ever seen. No lens-system has ever been coated to more stringent requirements for visual observation and for visual-photography as well.
