30 mm Cage Plate with Female D4T Dovetail and M4 Mounting Hole

The 30 mm Cage Plate, offered by Thorlabs, is a versatile component designed for use in cage systems. Its primary function is to provide a stable platform for mounting optical elements, facilitating the creation of custom optical setups.

This cage plate features a female D4T dovetail, a type of mount that ensures secure and precise alignment with other cage system components. The D4T dovetail is a widely adopted standard in cage systems, promoting interoperability between different brands and models.

The plate is made from aluminum, a material known for its lightweight yet robust properties. It is black anodized, a finishing process that enhances its durability and resistance to wear. The plate's thickness is 12.7 mm, providing a sturdy base for mounted optics.

The cage plate has an inner bore of 30 mm, which matches the cage system's rod-to-rod spacing. This ensures a snug fit and prevents any misalignment due to play. The optics diameter size can range from 30 to 30 mm, making it suitable for a variety of optical elements. The optic thickness should be at least 5.08 mm for a secure fit.

The plate also features M4 mounting holes, allowing for the attachment of posts or other components using M4 screws. This provides additional flexibility in designing your optical setup.
