Right Angle Adapter (RAA)

The Right Angle Adapter (RAA) is a useful attachment for the Point Source Microscope (PSM) that adds flexibility in mounting the PSM by allowing the objective to be attached at right angles to the body of the PSM. This can help when there is not enough room in a setup for the full length of the PSM body but there is room if the objective is effectively looking out the side of the PSM. If the PSM is mounted on a CMM then the RAA can be rotated to different angles rather than re-mounting the PSM to look at an object from different angle.
The RAA replaces the objective adapter in the PSM and the objective adapter is mounted in the RAA.
Price / kg:

The RAA, green, fits into the PSM body in place of the objective adapter, the brown circular piece, while the objective adapter is then attached to the RAA. Then the objective can be pointed in any direction at right angles to the PSM body. 

This mounting of the objective shortens the “length” of the PSM in tight alignment situations, and makes using the PSM on a CMM or machine tool much easier because the direction of the pointing of the objective can be changed by loosening the 4 set screws holding the RAA, rotating the RAA to the desired pointing direction and retightening the set screws.

Case Studies & Testimonials

  • How small can the PSM be used for centering on a cylindrical axis?

    The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?

    The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.

  • Why is proper alignment so important?

    Here is a case of a very happy customer due to better optics.

    A few days ago an astronomer friend of mine commented that he had gotten the optics of his telescope improved and the improvement reduced the time it took to get data by a factor of 3. For an astronomer this is a dramatic improvement since observing time on large telescopes can cost thousands of dollars an hour.

    My friend did not say how the optics had been improved, but the important point is that better optics, whether due to figure errors, mounting or alignment mean more productive optics. I generally think of better optics as a better product leaving the manufacturing facility without thinking about how much the better optics mean to the productivity of the customer.
