Baader Carl Zeiss 1¼" Abbe Barlow lense 2x 1603321
With 31.7mm Baader ClickLock clamp. The latest version of one of the finest astronomical barlows ever made has been manufactured exclusively for Baader Planetarium by Carl Zeiss.
One of the finest optical Barlow lenses ever made has now been fitted with Baaders Clicklock clamp, this genius move now means that changing eyepieces can be done speedily and effectively, even in the dark.
Even for non visual use, the top of the eyepiece clamp can be removed to expose T-threads, this enable the lens to be used for projection imaging or with an eyepiece for higher magnifications by adding T-2 extension tube (such as #2958130), or attach to a DSLR camera for 2.3x magnification using T-threads and T-adapter
The Carl Zeiss Abbe Barlow lens consists of two parts. The front barlow section ends with a photographic T-2 thread suitable to directly connect onto standard DSLR T-rings. , at the separation level a T-2 photo thread - mounted with our Baader ClickLock eyepiece clamp with the known rotary clamping system. A direct T-2 adaptation is possible.
An enlargement of the imaging scale up to three times is possible without loss of quality. 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 every camera, webcam or DSLR camera housing. If you add T-2 extensions the magnification can be extended by up to 3x. We recommend using our T-2 Varilock clamps for stepless adjusting of the optical length: Varilock 20-29mm (# 2956929) or Varilock 29-46mm (# 2956946)
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 VIS-photography as well.
