To calculate the Objective Spot Size (S):
\[ S = \frac{\lambda \cdot F}{\pi \cdot D} \]
Where:
The objective spot size refers to the diameter of the focused spot of light produced by an optical system, such as a microscope or a laser. This spot size is crucial in determining the resolution and precision of the optical system. A smaller spot size allows for higher resolution and more precise measurements or cuts, making it essential in applications like microscopy, laser cutting, and optical data storage. The spot size is influenced by factors such as the wavelength of the light, the focal length of the lens, and the diameter of the incoming beam.
Let's assume the following values:
Using the formula:
\[ S = \frac{0.0005 \cdot 100}{\pi \cdot 10} = 0.00159 \]
The objective spot size is 0.00159 mm.
Let's assume the following values:
Using the formula:
\[ S = \frac{0.0006 \cdot 150}{\pi \cdot 15} = 0.00191 \]
The objective spot size is 0.00191 mm.
