The field lens is a special focusing lens, which is characterized by that when the incident light is incident at different angles, the light output focus is on the same plane. With the scanning galvanometer and the corresponding control system, a high-precision, high-quality focus point can be achieved within the designed focal plane to meet the application needs of different industries.
1. All field lens optics and structural designs are specially optimized for different industry applications to ensure excellent processing effects and long-term stability.
2. Medium and high power use imported fused quartz, OH<200(ppm), with better optical uniformity and lower thermal drift.
3. Using ultra-low absorption coating technology, the single lens transmittance T>99.8%, the highest damage threshold reaches 40 J/cm² at 1064 nm, 10ns, 100Hz
