Frequently Asked Questions

An optical aperture is a device used to limit or shape the incident light in a beam. Apertures can be fixed or adjustable and come in a variety of shapes and sizes.

Some common shapes of apertures include circular, square, rectangular, and slits. Other custom shapes are also possible.

Apertures are used to control the size and shape of a laser beam, which can affect the laser's performance and accuracy.

Adjustable apertures are typically controlled using a manual or motorized mechanism that changes the size of the aperture opening.

Apertures can be made from a variety of materials, including metal, glass, and plastic. The choice of material depends on the intended application and required durability.

Apertures can be mounted using a variety of holders and mounts, including kinematic mounts, post mounts, and clamp mounts. The mounting method used depends on the specific requirements of the optical setup.

Looking for mechanical apertures for your laser optics, spectroscopy, industrial or scientific applications?
