Optical assembly

An optical assembly, comprising:

• a transparent substrate having substantially parallel first and second surfaces;
• a reflective portion on the transparent substrate;
• a plurality of filters filtering light beams incident thereon, the plurality of filters and the reflective portion forming a bounce cavity within the transparent substrate;
• an alignment mechanism accurately aligning the plurality of filters to a predetermined angle relative to the reflective portion;
• a tilt mechanism for introducing tilt to the light beams input to the bounce cavity;
• an
• input port adapted to receive light having a plurality of wavelengths;
• and
• a plurality of detectors adapted to receive a corresponding wavelength of the light received at the input port and incident on the bounce cavity.
