Adjustable collimator for coupling a light guide to a microscope

A microscope comprising:

• an objective lens;
• a lamphouse mount;
• an optical train which transmits light from the lamphouse mount to the objective lens;
• and
• an adjustable collimator wherein the adjustable collimator includes,
• a housing secured to the lamphouse mount,
• a housing bore, in the housing, the housing bore having a longitudinal axis aligned with the optical train,
• a housing lens secured in the housing bore aligned with the longitudinal axis,
• a sleeve slidingly received in the housing bore,
• a sleeve bore aligned with the longitudinal axis,
• a sleeve lens secured in the sleeve bore aligned with the longitudinal axis,
• a sleeve fastener for adjustably securing the position of the sleeve within the housing bore such that a first distance between the housing lens and sleeve lens may be adjusted and fixed;
• and
• a light guide fastener for adjustably securing a light guide within the sleeve bore such that a second distance between an output aperture of a light guide and the sleeve lens may be adjusted and fixed.

An adjustable collimator comprising:

• a housing having a housing bore having a longitudinal axis;
• a housing flange adapted to mount the housing to a microscope;
• a first lens secured in the housing bore aligned with the longitudinal axis;
• a second lens aligned with the longitudinal axis;
• an adjustment mechanism for adjustably securing the second lens such that a first distance between the first lens and second lens may be adjusted and fixed;
• and
• a light guide mount for adjustably securing a light guide such that the light guide is aligned with the longitudinal axis and a second distance between an output aperture of a light guide and the second lens may be adjusted and fixed.
