Raman Filters

• Using high purity optical substrates with low Raman effect (data available upon request)
• High OD laser-line blocking for maximum laser rejection (>6OD)
• Steep slopes to enable measuring the small Raman shifts (5OD slope: BPF: <4nm; LPF <10nm; 45deg dichroic: <10nm)
• High transmittance in the pass band (>90%)
• Typical 6OD Blocking Range: 0.85λ0 ~ 1.15λ0
• High laser damage threshold (>20J/cm2 @ 532nm)
• Superior environmental reliability
