   Mini Fiber Collimator

With unique fiber lensing technology and special processes, Sino Point is capable of supplying miniature fiber collimator with superior optical performances, such as extremely compact size, Gaussian beam output with small beam spot size, low coupling loss and high optical power handling capability, etc. These outstanding characteristics enable designs and manufacturing of valuable miniature fiber devices, such as FRM and EVOA, etc, especially for reducing the size and enhancing the reliability of fiber sensor head. The standard fiber pigtailing is with SMF28, but it can be customized and replaced with specialty fibers, according to customers’ requirements.
