Spacers for lens apparatuses are provided. In some embodiments, a spacer comprises: an inner circumference and an outer circumference; and one or more angled vertical components, each positioned along the outer circumference. The spacer may be configured to be positioned between two lenses of the lens apparatus. A region within the inner circumference may be configured to allow light to pass between the two lenses. An angled vertical component of the one or more angled vertical components may be positioned against an angled surface of at least one of the two lenses.

Lens spacers for lens stability

A measurement apparatus for measuring a laser focus spot size, which includes a two-dimensional image detector and an imaging system which forms a magnified image of a focus spot located an object plane onto the image detector. The imaging system includes at least an objective lens. A sealed liquid container is secured over a part of the objective lens such as the optical surface of the objective lens is immersed in the liquid (e.g. water) within the container. The liquid container has a window through which the laser beam enters. An image processing method is also disclosed which processes the image obtained by the image detector to obtain the focus spot size while implementing an algorithm that corrects for the effect of ambient vibration.
