Abstract:
An improved transceiver system for sending and receiving infrared signals, comprising:a housing further defined by a substantially transparent aperture, said aperture including a primary lens unit inserted into said aperture, and said primary lens unit further defining a primary refractive power to refract said signals by a primary refraction angle;at least one emitter located within said housing adjacent to said aperture;at least one detector also located within said housing adjacent to said aperture; anda secondary lens located adjacent to said aperture, said secondary lens defining a secondary refractive power to refract said signals by a secondary refraction angle, said secondary refraction angle being greater than zero degrees, wherein said secondary lens further comprises a tertiary refractive power to refract said signals by a tertiary refraction angle, said tertiary refraction angle being greater than or less than said secondary refraction angle;whereby said system defines a total refraction angle of refraction of said signals, said total refraction angle consisting of the primary refraction angle plus the secondary refraction angle.
