The F-number is only defined for objects at infinite distance. The sensor has according the definition of the focal length exactly the distance “focal loength” from the principal plane when the lens is focussed to infinity.

To keep the object focussed, the distance of lens and sensor must be increased. This is equivalent with adding distance rings reagrding the infinity position of the lens. As result the images gets darker the field of view gets smaller , the therefore the magnification changes.

The stage is comprised of a platform and base that are conjoined by a guide or linear bearing. This joining restricts the platform to linear motion. A linear stage also commonly utilizes a stepper motor. A stepper motor is a brushless, synchronous electric motor that can convert digital pulses into mechanical shaft rotations. A lead screw or worm gear drive are often accompany of a stepping motor to further linear motion control. For best results, a step motor can be used in conjunction with a stepping motor driver in microstep mode.

What exactly is a linear stage? It’s a positioning devices that increases high-precision motion while decreasing runout. More simply, this stage is used to restrict an object to a single axis of motion. The level of precision a linear stage provides is crucial in industrial and scientific operations, from photonics instrumentation to semiconductor manufacturing. Your options when it comes to selecting a linear stage range from more cost-effective products to more complex, high-performance models with air-bearing capabilities.

Focusable Collimators consist of a fiber optic collimator with a fiber optic refocusing assembly. Focusable Collimators are available at Edmund Optics.

Typically, objects can rotate along any of three axes, giving the object six degrees of freedom: three rotational and three translational. The linear stage restricts five of these axes, allowing the object to move on only one translational axis. When used properly, the linear stage provides a superior finished product quickly and efficiently.
