These pinhole cells are suitable for 25 mm dia. mounted pinholes. It can be used with rigid, kinematic, XY, XYZ and 5axis stages. The cell comes with standard RMS thread for fixing to various mounts.
These apertures are made in aluminium substrate and finished by black anodizing. The aperture can be mounted to our standard RLM-25 lens mount.
