beam dump  

Beam Dump

 

This beam dump is used in a laser angeoplasty unit.  A solenoid-driven semaphore mirror rotates into the beam path and diverts the beam into a beam dump.  The dump's incident surface is matte-finished copper with V grooves machined into the surface.   The energy of the incident beam not absorbed by the copper is thus reflected against the walls of the cylindrical light trap.  The dump is isolated from the surface of the optics mount by a thin bracket to reduce thermal distortion of the optics mount..

 

Laser Texturing Device For Rigid Disks

 

This is an execution of an optics schematic prepared by another consultant.  The beam from the main IR laser is split four ways to texture both sides of two disks simultaneously.  The beam from a diode laser is duplexed and retroreflected by the disk as feedback for focusing.  This prototype design is composed of off-the-shelf components.

Optics Head For Laser Texturing Device.

This design is part of a follow-on design of the unit shown above.  The optics head provides the adjustments necessary for final focus.  All adjustment is performed by elastic deformation of the mounts to eliminate all play in the mechanism.  A companion feature is a triangulation range finder  designed into the head to feed back the distance from the optics to  the disk surface.

CCD telescope

 

Telescope And Illumination System For Viewing Semiconductor Wafers.

This optics system was designed to view the surface of semiconductor wafers in a wafer prober using a CCD camera.  The optical axis is folded to reduce the footprint of the machine by allowing the path to fit within the ring carrier plate of the prober and to position the camera in the vertical plane at the outside edge of the machine.  The illumination system is composed of a ring of LED's with one located coaxial with the incident path.

 

Telescope With Zoom Feature

This telescope is designed with a sleeve containing a helical slot engaged with a pin holding the second optic.  Rotation of the sleeve changes the distance between the optics.  The application was used to adjust the divergence of a laser beam.
