Abstract
The techniques described herein relate to an apparatus including: a primary reflector including an orifice and a first reflective surface, the first reflective surface including a first region and a second region; and a secondary reflector including a second reflective surface facing the first reflective surface; wherein the first region, the second regions and the second reflective surface are configured such that the apparatus provides a two-bounce beam path through the apparatus and an independent four-bounce beam path through the apparatus.

An apparatus comprising:
- a primary reflector comprising an orifice and a first reflective surface, the first reflective surface comprising a first region and a second region;
- and
- a secondary reflector comprising a second reflective surface facing the first reflective surface;
- wherein the first region and the second reflective surface are configured such that the apparatus provides a first beam path in which light of the first beam path reflects off the first region to the second reflective surface, and reflects off the second reflective surface through the orifice, and
- wherein the first region, the second region and the second reflective surface are configured such that the apparatus provides a second beam path in which light of the second beam path reflects off the first region to the second reflective surface, reflects of the second reflective surface onto the second region, reflects off the second region to the second reflective surface, and reflects off the second reflective surface through the orifice.

An apparatus comprising:
- a primary reflector comprising a first orifice and a first reflective surface;
- a secondary reflector comprising a second reflective surface facing the first reflective surface;
- and
- a third reflector comprising a second orifice and a third reflective surface facing the second reflective surface;
- wherein the primary reflector, secondary reflector and third reflector are configured such that the apparatus provides a first beam path in which light of the first beam path reflects off the first reflective surface to the second reflective surface and reflects off the second reflective surface through the first orifice and the second orifice, and
- wherein the primary reflector, the secondary reflector and the third reflector are configured such that the apparatus provides a second beam path in which light of the second beam path reflects off the first reflective surface to the second reflective surface, reflects off the second reflective surface to the third reflective surface, reflects off the third reflective surface to the second reflective surface, and reflects off the second reflective surface through the second orifice and the first orifice.

An apparatus comprising:
- a primary reflector comprising a first orifice and a first reflective surface;
- a secondary reflector comprising a second reflective surface facing the first reflective surface;
- a third reflector comprising a second orifice and a third reflective surface facing the second reflective surface;
- and
- a fourth reflector comprising a fourth reflective surface facing the third reflective surface;
- wherein the primary reflector, secondary reflector and third reflector are configured such that the apparatus provides a first beam path in which light of the first beam path reflects off the first reflective surface, to the second reflective surface and reflects off the second reflective surface through the first orifice and the second orifice, and
- wherein the primary reflector, the secondary reflector, the third reflector and the fourth reflector are configured such that the apparatus provides a second beam path in which light of the second beam path reflects off the first reflective surface to the second reflective surface, reflects off the second reflective surface to the third reflective surface, reflects off the third reflective surface to the fourth reflective surface, and reflects off the fourth reflective surface through the second orifice and the first orifice.
