摘要:
An optical system having at least one dichroic Mangin mirror. The optical system has a front-end optical sub-system or a light source operative to emit an optical beam. The optical beam is dispersed into at least a first color beam and a second color beam and has certain degree of monochromatic aberration. The dichroic Mangin mirror is disposed along the optical paths of both the first and second color beams. The dichroic Mangin mirror includes a first surface operative to transmit the first color beam only, but reflects the second color beam. Therefore, upon incident on the dichroic Mangin mirror, the second color beam is reflected, while the first color beam transmits through the first surface and is then reflected off from the second surface. Thereby, the first and second color beams can be focused at the same position, which is referred as an achromatic system focus. Thereby, the chromatic aberration caused by the dispersion can be eliminated.

摘要:
A laser module with integral cooling is disclosed. The module is intended for coupling to a fiber optic cable for various applications. The module is generally cylindrical and has a laser diode array mounted centrally therein. A cooling channel is in thermal relation with the array either directly or via a diamond substrate. A fiber optic coupler mates with the portion of the housing carrying the array and carries a lens subassembly. During assembly, the coupler is positioned to accurately focus the output of the array into a beam suitable for transmission to the fiber optic cable. Coolant is coupled to the channel with a removable coupling manifold or similar arrangement which may also carry electrical contacts for energizing the array.
