In the world of laser hair removal, precision, power, and safety are non-negotiable. At Mico Aes, we integrate the latest optical innovations into our machines to deliver outstanding treatment results. One such game-changing feature in our 808nm diode laser hair removal machines est FAC technology, short for Fast Axis Collimation.
But what is FAC, and why does it matter so much? Let’s break it down.
What Is FAC Technology?
Every laser diode emits light beams that naturally spread out—especially in the fast axis direction, where divergence is strongest. This can result in an unfocused beam, lower energy density, and inefficient skin penetration.
FAC (Fast Axis Collimation) is a lens system that straightens the beam emitted by each diode. It collimates the fast axis of the laser beam, making the light more parallel, narrow, and precise.
FAC (Fast-Axis Collimation) technology improves the efficiency of the 808 nm diode laser primarily by enhancing the beam quality and energy transmission, which leads to better overall laser performance and output power.
Why FAC Technology Matters in 808nm Diode Lasers
À Mico Aes, our 808nm diode lasers equipped with FAC lenses deliver optimized performance in the following ways:
✅Superior Beam Collimation and Quality
FAC lenses are aspheric cylindrical lenses with a high numerical aperture (NA ~0.8) that collimate the fast-axis output of the laser diode. This collimation reduces the beam divergence in the fast axis, producing a beam with a smaller divergence angle and higher uniformity. This improved beam quality allows for more precise focusing and better coupling into optical fibers or delivery systems, which is critical for applications like hair removal.
✅Higher Transmission and Energy Conversion
With a collimated beam, more laser power is concentrated and directed exactly where it’s needed—at the hair follicle. This improves energy delivery per shot, leading to better clinical outcomes and less wasted energy.
FAC lenses have very high transmission rates (up to 99%) across the laser’s spectral range. This means less energy is lost inside the optical system, resulting in more efficient light delivery and higher output power from the diode laser.
✅ Improved Light Guide and Uniformity
Compared to traditional diode lasers without FAC, the light guide performance can increase by about 25%, and light uniformity improves by approximately 20%. This means the laser energy is distributed more evenly and efficiently, enhancing treatment effectiveness and reducing wasted energy.
✅ Stable and Reliable Output
The collimated beam from FAC technology maintains stable output power over a range of operating conditions, improving reliability and lifespan of the diode laser. Reduced thermal and optical losses also contribute to longer operational lifetimes and less maintenance.
✅Deeper and More Consistent Penetration
The collimated beam penetrates deeper into the dermis where hair follicles reside, ensuring more permanent hair reduction with fewer sessions.
✅ Faster Treatment Times
Because of higher precision and focused energy, the treatment area can be covered more effectively, reducing session duration. Clinics can serve more clients per day, boosting business efficiency.
