Optec TCF-S3i 3" Focuser

The TCF-S has a new big brother - the TCF-S3i. This 5 pound focuser has all the same features of the TCF-S but is just bigger and stronger. With the every increasing size of CCD cameras and associated instruments, the need for a precision digital focuser that can take the weight and is compatible with most of the camera control software available is now met. Focuser control is now accomplished via direct serial connection between the focuser and computer.

No corners were cut with this model. The massive drawtube has a 3.00-inch I.D. and is made from 7075, the strongest of the commercial aluminum alloys. To prevent any slippage common to Crayford style focusers, the drive rod is pressed onto the drawtube with a force of about 500 pounds. The TCF-S3i can take this extreme pressure because the drive rod is made from a ground bar of high speed steel with a diameter of 0.375 inch. Hardened rails of stainless steel are embedded in the drawtube to engage the drive rod and take the strain.

The total linear travel of the drawtube is 1.00-inch with a resolution of 0.0001-inch. Like the TCF-Si, serial computer interface and digital display control all functions of the TCF-S3i. All other features of the TCF-S3i are similar to the TCF-S. It uses the same cables, temperature probe, but focuser control is now accomplished via direct serial connection between the focuser and computer. It is also compatible with the current Optec control software TCF-S.exe. This focuser is only intended for large scope with massive mounts.
