Stackrail RS-90 P Focus Stacking Machines for USB and Bluetooth

  • RS-90P precision (400 step/rev motor), capable of up to 50x magnification work. 0.625 um per step

This is a focus stacking kit using our motion control RS90 p. We have 4 sets available, for USB and BLUETOOTH, android and iphone....This is our motion control rail with minimum 80mm travel distance. The rail can be controlled by either our USB based (for PC only) or our Bluetooth BLE based motion/time lapse controller for PC or Bluetooth BLE capable phones, such as iPhone, Android Phone. Smallest step on SR-90 is 0.625um.

NEW : Precision RS-90 P SET & Remote Controller No need for a PC, Laptop, Phone or Tablet.

Focus Stacking ?
Focus stacking is a powerful method to extend depth of field by taking a series of images at different focal plane and use computer software to pick the sharpest part of each image for the final result. One way to acquire such series of images is by moving the camera towards or away from the subject (or by moving subject towards or away from the camera) so that different part of the subject will be in focus in each image. Then by applying computer algorithm, these images will be combined into one sharp image.

In order to move the camera (or the subject for that matter) and automate the process of image captures, an automated rail system is preferred method.
However, current products on the market are extremely expensive and many macro photographers have to do it manually which is a tedious work to do. Besides expensive rail system, good stacking software are either expensive (but really good) or difficult to use (though free).

The goal of this project is to offer macro photographers with three solid solutions for focus stacking at affordable prices and ease of use.

This is a demonstration of focus stacking software and hardware.

This is a demonstration of using an iOS device (iPhone 4S in this case) to control our StackRail systems (SR-90, PR-18, PR-110, and other custom rails compatible with our motor drive box)

Just to show our rail in action. Lens is Laowa 60mm Macro Lens. This is exaggeration of actual stacking because there is no flash. Lens is Laowa 60mm Macro Lens.
