Abstract
Abstract A housing for positioning a discrete optoelectronic emitter and a discrete optoelectronic sensor to function as a coupler. The same housing provides the option for either reflective or transmissive mode operation. The discrete devices are removable to permit substitutions of devices having differing characteristics.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
81 words
A housing for at least a pair of separately-packaged optoelectronic devices including an optical emitter and an optical sensor comprising: a body containing receptor cavities for holding said emitter and said sensor in predetermined positions and providing at least two optical paths between said emitter and said sensor devices; a first of said optical paths optically coupling said emitter and said sensor directly and a second of said optical paths being indirect and incomplete without reflective means external to said housing.
Claim 2
Dependent Claim
81 words
A housing for at least a pair of separately-packaged optoelectronic devices including an optical emitter and an optical sensor comprising: a body containing receptor cavities for holding said emitter and said sensor in predetermined positions and providing at least two optical paths between said emitter and said sensor devices; a first of said optical paths optically coupling said emitter and said sensor directly and a second of said optical paths being indirect and incomplete without reflective means external to said housing.
Claim 3
Dependent Claim
26 words
The housing of claim 1 further comprising channel means in said body generally transverse to said first optical path to permit interruption of said optical coupling.
