Multiple afocal adaptor for mobile devices
In some aspects, an afocal adaptor for an optical device comprises a housing. The housing includes a first and a second optical channel. A divider is configured between the first optical channel and the second optical channel to prevent transmission of electromagnetic radiation between the first optical channel and the second optical channel. At least one lens is associated with each of the first optical channel and the second optical channel. A particular at least one lens is configured to provide a focal point for each of the first optical channel and the second optical channel and to guide a particular type of electromagnetic radiation through each of the first optical channel and the second optical channel. The electromagnetic radiation is guided into a corresponding first receiving optical channel and a second receiving optical channel associated with the optical device. A coupling mechanism is attached to the housing and configured to permit attachment of the housing to the optical device.
