Fixed focus large beam collimatorator

It can collimate and reshape the output light of the optical fiber, which is used for the laser emitted from different optical fiber connections, providing diffraction limit performance at the design wavelength, and the collimation distance can reach 200 meters.

Fiber optic collimator with FC/APC, FC/PC, or Sma905 connectors

Can be used in the wavelength range of 405 nm to 1.55 μ m

Simplify the coupling of free space laser to optical fibers

Dual lens design, with aberration cancelling performance

Non magnetic stainless steel casing

Beam waist spot diameter: take 1/e2 of the Gaussian beam, and select the theoretical calculation value of single-mode fiber at each wavelength.

Far field divergence angle of the beam: input single mode fiber of each wavelength, and calculate the value according to the Gaussian beam 1/e2 theory. Tolerance+0.01 °/0.0 °
