Focus adjustable collimator

• Output light from collimated fibers
• Wavelength range (nm): 350-650, 650-1050, 1050-1600
• Focal length (mm): 6.2, 9.6, 11
• PC/FC fiber optic splices

Dimension-Labs Adjustable Focus Collimators are designed for collimation of fiber output light, and include an aspherical lens with a reflection enhancement coating, and three different sizes of aspherical lenses can be mounted in the same mechanical sleeve for collimating lasers with different beam diameters. By adjusting the distance between the aspherical lens and the fiber optic endface, it is possible to compensate for focal length changes or re-collimate at the desired wavelength and distance. It can also be used to adjust the divergence angle of the beam at the same wavelength, and apply the divergence and focus of space laser.

Application scenarios

• Fiber laser collimation is free space light
• Fiber laser collimation of different wavelengths
• Used to calibrate and test the performance of other optical components
• Optical fiber communication system to adjust the collimation of the beam to ensure the efficient transmission of optical signals
