Fibre-optic amplifier

For a fibre-optic amplifier the transmitter and receiver are incorporated into one housing. Depending on the version the transmitter emits an infrared or red light beam. A fibre-optic amplifier has no lens since fibre optics have to be connected to it.
Fibre optics

Fibre optics can be considered to be a prolongation of the optical components of the fibre-optic amplifier. Through-beam and diffuse reflection versions are available depending on the detection task. Fibre optics with glass fibres and metal sheath can be used in hot applications. For standard applications inexpensive fibre optics with acrylic fibres are available.
