High Transmittance Filters (Anti-Reflection Windows)
High Transmittance Filters, also referred to as Anti-Reflection (AR) Filters or Laser Protective Windows, are high-precision optical components engineered to prevent dust and contaminant ingress while maintaining optimal beam performance.
Functions:
Featuring high throughput, minimal back-reflection, and extremely low optical absorption, these filters allow laser light to pass with less than 1% total energy loss and under 0.5% internal reflection back into the optical system.
Applications:
Blue, green, and red laser equipment
Automated Optical Inspection (AOI) systems
Optical sensor protection.

Information and Notes
1. Our color separation filters are manufactured using vacuum thin-film deposition with 24 to 48 dielectric layers, customizable to meet specific optical performance requirements.
2. Precision coating process utilizing Physical Vapor Deposition with Electron Beam Gun Evaporation (PVD-EBGE).
3. Spectral performance curves are measured at normal incidence (0° angle of incidence). Blocking efficiency in the rejection band is achieved through dielectric film reflection.
4. Spectral curves represent actual sample measurement data. Minor lot-to-lot variations may occur within standard manufacturing tolerances while fully adhering to specified optical definitions.
5. Website specifications are provided for reference only. Final production and delivery comply with mutually agreed engineering specifications.
