a|VariColl
Looking for a solution to easily change the EFL of your fiber collimator while easily connecting the FC/PC patch fiber to your setup? Discover a|VariColl – our latest fiber collimator/fiber coupler. With separate divergence and beam diameter adjustment capability, it’s perfect for illuminating beam-shaping optics such as a|TopShape, a|AiryShape, and a|SqAiryShape. Available in design wavelengths of 532 nm, 632 nm, 780 nm, and 1064 nm, the adjustable effective focal length allows compensation for manufacturing-related variations in fiber NA (numerical aperture). Thanks to its high-precision optics and the sophisticated optomechanical design, beam size and divergence angle can be easily and independently modified with the a|VariColl. The fiber collimator/fiber coupler generates collimated beams with a diameter of 10 mm for fiber NAs ranging from 0.055 to 0.12 and for a wide spectral range of 500–1,200 nm.
