Silicon aperture frames are 3mm diameter discs of thickness 200µm containing square or rectangular apertures of three sizes. They are suitable for use as a support frame to attach TEM lamellae made with FIB instruments to allow for subsequent sample processing and TEM imaging. They are fully compatible with standard TEM holders. The aperture openings have a side window angle of 35.26° to allow for easy access.
