Product Detail
The Stand for Optical Bench Accessories, commonly known as a Carriage or Slider, is the mobile interface between the optical bench rail and the various components like lens holders, screens, and light sources. Its primary job is to provide a stable, vertically aligned base that can move smoothly along the bench.
Primary Function: To hold optical accessories at a fixed height and allow them to be positioned at specific distances along the graduated scale of the optical bench.
Design & Construction:
The Base: Usually made of cast iron or heavy aluminum alloy to ensure a low center of gravity and stability. The bottom is machined to fit perfectly over the specific profile of the bench (either twin rods or a triangular/rectangular rail).
Mounting Hole: A central vertical hole, typically 10mm in diameter, designed to receive the mounting rods (stems) of lens holders, needles, or screens.
Locking Screws: * Horizontal Lock: A thumb screw on the side that clamps the carriage to the bench rail once the desired position is reached.
Vertical Lock: A second screw that secures the accessory rod inside the mounting hole, allowing for height adjustment.
Index Mark: A small notch or "fiducial mark" on the side of the base that aligns with the bench's millimeter scale, allowing for precise readings of the component's position
