Plastic fast axis collimating lenses
Laser Components offers plastic Fast Axis Collimating (FAC) lenses for use with its wide range of laser diode products. Most laser diodes emit a divergent elliptical beam due to the construction of the laser diode and its output aperture. FAC lenses are therefore required to create a parallel beam either for free space applications or for coupling efficiently into an optical fibre.
The company says the inexpensive price of plastic lenses makes them an ideal choice for high volume visible and NIR laser module manufacture, which are used in a variety of medical applications from alignment to spectroscopy. The plastic lenses have an operating temperature between 0 to +65 °C. Laser Components offers plastic lenses with diameters ranging from 4.0-7.4mm and with focal distance from 3.33mm to 18.33mm. They can be mounted using glue or via a sprung loaded mechanism to avoid possible distortions.
