confocal mirror的意思|示意

Confocal mirrors，sometimes referred to as a focusing mirror，are optical devices used to direct and converge light in order to focus it onto a single point. The mirror is often used in laser scanning microscopy and laser-based 3D imaging.

Confocal mirrors are typically used in two-photon laser scanning microscopy (TPLSM) systems, where more precise focusing is required than for single-photon systems. The mirrors are designed to focus the laser spot down to a smaller spot size, allowing for a more precise and higher-resolution image collection.

The mirror has a flat surface with precise concentric rings etched on its surface. These rings can be adjusted to focus the laser spot onto a single point. The mirror is mounted on a precision-controlled motor and can be adjusted separately in both the x- and y-axes.

When the laser beam hits the mirror, the concentric rings scatter the light on the lens, which then focuses it to the desired point. The focal distance and spot size of the focused laser are adjustable, allowing the user to customize the laser spot size as needed.

Confocal mirrors are also used in various laser-based 3D imaging systems. They can be used to focus the laser beam onto a 3D object, allowing the user to capture a 3D image. The mirror is again mounted on a motor to allow for adjustable scanning and focusing of the laser.

In conclusion, confocal mirrors are a useful optical device used for precision laser focusing and 3D imaging. They are typically used in laser scanning microscopy systems and laser-based 3D imaging systems. The mirrors are adjustable and provide the user with precise laser spot size control.
