  • M68 VariLock Extension – 15-20 mm

    The M68 VariLock Extension provides a continuous adjustment range from 15mm to 20mm, replacing an entire set of fixed M68 spacer rings within its range. This component is essential for achieving the exact back focus required by field flatteners and reducers, with a millimeter scale for repeatable settings.

    Precise M68 Spacing: Dial in 15mm to 20mm of Back Focus

    Achieving perfect star correction across the field depends on hitting a precise back focus distance, often to within a fraction of a millimeter. The M68 VariLock allows you to dial in any spacing between 15mm and 20mm, providing the fine control that fixed-length spacers cannot. This eliminates the trial-and-error of stacking shims and ensures your optical corrector performs exactly as designed.

  • What is the primary use for the M68 VariLock 15-20mm Extension?

    The M68 VariLock is designed for fine-tuning the back focus distance in an M68-threaded imaging train. It is crucial when using field flatteners or focal reducers that require a very specific distance to the sensor for optimal performance, allowing you to achieve any spacing between 15mm and 20mm.

    Can I use the M68 VariLock to set a back focus of 17.5mm for my reducer?

    Yes, absolutely. The M68 VariLock's continuous 15mm to 20mm adjustment range covers 17.5mm perfectly. You can set it to that exact distance, lock it down, and be confident your spacing is correct without needing to stack multiple fixed-length spacers.

    Is the M68 VariLock compatible with accessories from other brands?

    The M68 VariLock uses the standard M68x1 thread pitch. It is designed to integrate with other components that use this common large-format thread, making it a versatile tool for building robust imaging trains with parts from various manufacturers.
