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? FindLight's selection of fixed or adjustable apertures can help limit or shape your incident light. Our vendors offer a variety of sizes and materials to suit your needs. Explore our range now.

Did You know?

Did you know that apertures play a critical role in many optical systems? Mechanical apertures are used to control the size, shape, and direction of light beams in applications ranging from laser systems to astronomical telescopes. They can be fixed or adjustable, and can be designed with various shapes and sizes depending on the specific requirements of the application. Apertures can also be used to remove unwanted background noise in imaging systems, and to improve contrast and resolution in microscopy and spectroscopy.
