1. A light transformer comprising:

  • a first end that receives light from the light source;

    a second end that outputs the received light, the second end located on an opposite end of the transformer from the first end;

    a first member located on a third end of the transformer between the first end and the second end, wherein the first member has an outer wall comprising a total internal reflection surface that redirects and redistributes the received light in a direction of the second end;

    a first optical window located at an end of the first member;

    a second member located on a fourth end of device, the fourth end located on an opposite end of the transformer from the third end, between the first end and the second end, the second member having an outer wall comprising a total internal reflection surface which redirects and redistributes the received light in a direction of the second end;

    a second optical window located at an end of the second member, the second optical window further being symmetrical across the axis of light direction with the first optical window; and

    an aspheric lens located between the first and the second members, the aspheric lens having an input side on the first end of device and an output side on the second end of device, the output side of aspheric lens located between the first and the second optical windows.
