Product Description
Direct T-2 Adaption Possible - Extends Magnification up to 3x - Without Quality Loss
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)
The Baader Barlow Lenses at a Glance
With currently five different barlow lenses in Baader Planetarium's product range, it is not easy to keep track of which model fulfils which function best.
 Fluorite Flatfield Converter (FFC) / 3x-8x (#2458200) |
90mm field of view also for medium format cameras - uncompromising quality even for extreme enlargements. Focus gain: depending on configuration about 1.5-2.6cm |
 Carl Zeiss 1¼" Abbe Barlow lens 2x (#1603321) |
Legendary Zeiss quality for the common magnification range between 2x and 3x (with additional T-2 extensions). With T-2 connection for cameras or eyepiece clamps. The qualitatively equivalent solution to the Fluorite FFC when smaller field size and smaller post-magnification are desired. Focus gain: About 3 cm |
 VIP 2x modular barlow lens, visual and photographic (#2406101) |
Versatile barlow lens for magnifications from 2x, for use with cameras (via T-2 thread) and eyepieces. Calculated for 35mm image diagonal (full format). With additional T-2 extensions it can also be used for slightly higher magnification factors. Focus gain at 2x: Approx. 3.3 cm |
 Baader Q-Barlow 1.3x/ 2.25x (#2956185) |
Inexpensive and amazingly high quality Barlow lens for the lower magnification range: In addition to being used as a normal Barlow lens with eyepiece clamp (with factor 2.25x), the Barlow element can also be used as a negative lens group when screwed directly into (almost) all eyepiece sleeves or directly in front of a camera with 1.25" filter thread and then provides a lower magnification of approximately 1.3x. Ideal for adapting a modern planetary camera to the resolution of an already long focal length telescope. Prerequisite: There must be no other elements in the nose piece that would prevent the approximeately 13 mm long Q-Barlow lens group from being screwed in. Focus gain at 2.25x: About 0.4 cm |
 Hyperion Zoom 2.25x Barlow lens (#2956180) |
Specially designed for the Hyperion Zoom eyepiece, also fits the filter thread of other eyepieces.
With the included T-2 adapter, it can also be used directly on cameras; provides about 2.7x at 55mm working distance and about 2.3x at 25mm. Focus gain: About 1.1 cm |
