Laser light can be delivered to any location with the use of fibre optics, however, one challenge is to efficiently couple the light into and out of the fibre. In general it is necessary to collimate the laser beam during output coupling.
To make this process as simple as possible, we have developed focusable fibre optic collimators, manufactured in Germany. Available in two diameters, Ø11.5 mm and Ø19 mm, these collimators are suitable for step-index fibres with 0.22 NA, with single-mode fibres, and CO2 fibres with Ø750 µm or Ø1000 µm core diameters.
These collimators consist of lens systems that are anti-reflection coated for different wavelength ranges. Choose any of the standard wavelengths 350-700 nm, 650-1050 nm, 1050-1060 nm, or 10.6 µm.
Furthermore, the focal length of the system can also be selected. Depending on the application, the beam diameter requirements are very different. The correlation between beam diameter and operating distance is shown on the product datasheet.
All collimators can include connectors, such as; SMA, FC wide key, FC small key, FC/APC wide key, and FC/APC small key. Other connectors are also available upon request.
