Features

Optical Post Collars

Optical post collars provide an index point for a specific post height, allowing an optical post to be removed from an optical post holder and returned to the same height. They can also be used to rotate an optical post while keeping it's height constant. Newport's C-0.3 open-ring post collar for miniature optical posts allows it to be added without having to remove the post from the post holder.

The Miniature C-0.3 and Standard C-0.5 Optical Post Collars shown mounted to MSP and SP Series Optical Posts

Optical Post Clamps

MCA-1 Right-Angle Optical Post Clamps mount two MSP Series optical posts, respectively, at 90° to each other. The clamping screws permit fast, secure post mounting with only moderate finger pressure.
MCA-2 Adjustable-Angle Post Clamps hold two MSP Series Posts, respectively, at an arbitrary angle with respect to each other. Both posts are tightened simultaneously with the knurled knob.

Optical Filter Post Mounts

The MFC-1 Filter Clamp is convenient for holding thin objects such as optical filters, transparencies or even razor blades used as knife edges. An 8-32 (M4) set screw may be threaded into the Delrin clamp for attachment to the end of an MSP Series optical post.
