BH square diffusers (Broadband high Homogeniety diffusers) are special flat-top beam shaping micro-refractive line diffusers, based on double sided square packed micro lens arrays.
Useful for any laser application where shaping needs to be sharp, regardless of laser M2 , the BH square diffuser offers excellent efficiency and uniformity within the sharp square shape.
Typical applications include:
- UV laser curing, de bonding, annealing and other processing
- Semiconductor wafer defect. inspection
- Multi KW ~1um IR laser processing – plate welding, sintering , hardening
By combining precisely controlled diffusion into the surfaces of the lens arrays, our BH square diffuser offers several advantages over standard fly eye type diffusers:
- Excellent uniformity – the addition of random diffusion eliminates order artifacts that exist in standard double sided square lens arrays.
- High efficiency (>95%)
- UV fused silica material, optimal for high power and UV laser applications.
- Same performance for a wide wavelength spectrum from IR to UV.
