Optical Rails Guide
Elements required for configuring an optical system are often arranged along a straight line due to the linearity of light.
An optical rail is a basic unit for configuring optical systems and consists of the rail itself, a carrier for mounting components and feet for stabilizing and securing the assembly.
Optical rails simplify the adjustment of intervals between components because they allow adjustment by sliding a carrier while maintaining the optical axis.
