What is FAC?

FAC (FACFast-Axis-Collimator) is the Fast-Axis Collimator; FAC (Fast-Axis Collimator) lens has excellent collimation and transmittance, FAC lens is an important optical component on the semiconductor laser, which is very important for beam shaping and modification.

What is FAC Fast Axis Collimation and Compression Technology?

Semiconductor laser with FAC fast axis collimation and compression technology:
It can effectively reduce the divergence angle of the laser output; make the laser output more uniform and more concentrated energy; it can reduce the damage caused to the laser by optical path folding.

What are the advantages of the semiconductor laser handle with FAC collimated compression technology?

Semiconductor laser handles with FAC collimation and compression technology can effectively reduce the laser output dispersion angle, making the handles output more uniform laser light and more concentrated energy, resulting in better clinical hair removal;

Semiconductor laser handle with FAC collimation and compression technology can reduce the damage to the laser caused by optical path folding, thus effectively improving the service life of the handle laser;

The semiconductor laser handle with FAC collimation and compression technology can reduce the laser output dispersion angle and reduce the optical path folding loss, which can reduce the optical heat loss and effectively improve the cooling effect of the handle;

The use of FAC fast axis collimation technology of the laser, more stable performance, and lower return rate has become a mainstream product.
