– Using high purity optical substrateswith low Raman effect( data available upon request )

– High OD laser-line blocking for maximum laser rejection ( > 6 OD )

– Steep slopes to enable measuring the small Raman shifts ( 5 OD slope: BPF: < 4nm; LPF

< 10nm; 45 deg dichroic: < 10nm )- High transmittance in the pass band ( > 90% )

– Typical 6 OD Blocking Range: 0.85λ0 ~ 1.15λ0

– High laser damage threshold ( > 20J/cm2 @ 532nm )

– Superior environmental reliability
