FLI 5 Position Color Filter Wheel (for 2" or 50mm diameter filters) [FLI-CFW1-5]

FLI-CFW1-5

Availability: usually ships within 10-14 days
Flight Lakes Instrumentation: FLI 5 Position Color Filter Wheel (for 2" or 50mm diameter filters)
At less than 7/8 of an inch thick, the CFW-1 color filter wheel is designed to closely and rigidly couple to any CCD camera. The homing device of the CFW is highly accurate and repeatable. The recessed opening of the color filter wheel securely clamps to an IMG, MaxCam, or "AD" adapter mounting flange. This setup adds a minimum distance to the light path and avoids the vignetting issues common with other designs.
The T-mount system was introduced by Tamron in 1957 as a universal lens mount for 35mm cameras. The idea was that each lens would have a standard threaded rear flange. A camera specific adapter would then be attached at the point of sale, as needed. This greatly reduced costs since only the T-mount adapters needed to be stocked, rather than different versions of every lens.
With T-mounts readily available for most camera bodies, it was natural for astronomy buffs to settle on it as the standard adapter for 35mm astrophotography. Without this inexpensive and easy to use adapter, astrophotography might have gotten off to a far slower start than it did. On the downside, the T-mount was designed to solve a very specific optical coupling problem in 35mm cameras. Progress in telescope design and CCD array size is revealing the T-mount as a potential bottleneck in the light path.
Color Filter Wheels
Our color filter wheel’s robust mechanical design provides the basis for stunning, uncompromising images. Each FLI color filter wheel is precision engineered with a highly accurate no-slip drive chain and stepper motor. The large diameter pivot pin and bushings are precision ground and matched for smooth, quiet no-fuss operation night after night. FLI color filter wheels do not use internal lights for homing, so your images are protected from stray light interference.
FLI's proprietary Zero Tilt Adapter (ZTA™)
The ZTA™ is an FLI adapter design that eliminates the common deficiencies found in most astronomical adapters. When you use the ZTA™ you will never experience tilted components, marred adapters, or wobbly interfaces!
 
The ZTA™ adapter system employs a circular spring that evenly distributes the pressure of three set screws against the ZTA™ dovetailed surface. The resulting clamping force between the two machined surfaces results in zero tilt, zero adapter marring and a complete elimination of problems associated with loose connections. The ZTA™ adapter can be machined to fit nearly any type of camera, color filter wheel or telescope.
 
ZTA™ - featured in the Atlas focuser and the CenterLine color filter wheel.
