An optical system has a hollow mechanical body having first and second ends. An optical assembly has a plurality of optical components arranged in a stack configuration. Each of the optical components has a set of engagement configurations. For each pair of adjacent optical components in the stack configuration, at least some of the engagement configurations of a first optical component in the pair engage with at least some of the engagement configurations of a second optical component in the pair. Some of the engagement configurations of the optical component at a first end of the stack configuration engage with corresponding engagement configurations of the hollow mechanical body at the first end of the hollow mechanical body to position the other optical components of the stack configuration within the hollow mechanical body. An emissive display device is deployed at the second end of the hollow mechanical body.

An optical assembly a substrate having a first surface and a second surface that is opposite to and substantially parallel with the first surface. The first surface has a first curved profile and the second surface has a second curved profile. The optical assembly also includes a beam splitter on the first surface and a reflector on the second surface. The optical assembly is configured to transmit image light received at the first surface in an optical path that includes reflection at each of the reflector and the beam splitter before the image light is output from the second surface. The optical assembly is also configured to transmit ambient light received at the first surface such that the second light is output from the second surface without undergoing reflection at either the reflector or the beam splitter. A method of transmitting light through the optical assembly is also disclosed.
