CaF2 Fluorit Flatfield Converter... the sharpest Barlow which we know!

We are happy to offer this product to you: The CaF2 Fluorit Flatfield converter! This interesting accessory has been designed by one of the Zeiss APQ engineers together with Baader Planetarium.

The FFC is nothing less than one of the best projective that has ever been developed. It is by the factor of 10 more precise than the best projection eyepieces. Not only on the optical axis but also in the field that illuminates up to 6x6 format.

Visual use:

The Fluorit Flattfield Converter (briefly FFC) is the most versatile and highest quality Barlow which we know. It offers the possibility of raising magnificationi by the factor of 3 to 8 with no visible loss of optical performance. For instance, turn your 30mm 2" eyepiece with comfortable eye relief to a 4mm planetary eyepiece without changing the viewing position.

Photographical use:

The FFC has a female T2 thread on the telescope side and a male T2 thread on the camera side. With these standard connections, the FFC is very versatile to use and fits to any tele objective with T2 thread. Via the adaptations we offer in the "accessories" section you can adapt the FFC to nearly any telescope. In photographical use, the FFC offers prolonging the focal length by a factor from 3 to 8.

What differenciates between a FFC of a Barlow lens or a photo converter?

With correct adaptations, the FFC allows extreme conversion factors with no loss of optical performance (neither on-axis nor in the field). It offers flexible conversion factors of 3x to 8x with pinpoint star pictures whereas normal Barlow lenses only allow 2x, 3x or 5x, according to their individual design.

In any field the FFC is better than any Barlow or converter we know.

Solar observing and photography:

The FFC may not be used for projection tasks in direct solar light - same as with standard eyepieces, filters and Barlows. Otherwise it could be damaged by heat. On the other hand, the usage with objective solar filters and Herschel prisms is no problem.

Connection to the telescope:

On the telescope side, the FFC has a female T2 thread. Find all necessary accessories below, e.g.:

Adaptor to 1.25" focusers: article BA 2458105
Adaptor to 2" focuser: article BA 2408150
Adaptor to male SC thread: TS SC-T2

Connection of eyepieces and cameras:

Here, the FFC has a male T2 thread. Find all necessary accessories below, e.g.:

SLR cameras: many T2 rings
1.25" eyepieces: article TS T2-1-T2
2" eyepieces: article TS T2 - 2
Connection of accessories with SC thread: BA 2408135

How do I reach the desired extension factor?

The longer the distance between the FFC and the eyepiece / camera is, the longer the extension factor will be. You can set this factor by placing T2 extension tubes between FFC and eyepiece / camera. The same effect can be reached by using diagonal prisms or -mirrors for visual use.

For instance, if you attach the FFC directly to a SLR camera, you reach an extension factor of 3. Same, if you have a distance of 55mm between FFC and the eyepiece's field stop.

If you go 40mm further (e.g. with the 40mm T2 extension tube), the extension factor is 4. If you add a second 40mm extension, the factor is 5 and so on.
