Datasheet (PDF)
Lightwaves2020’s leading-edge Raman filters have the following
features:
 Features
- Using high purity optical substrates with low Raman effect;
- 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; 45deg dichroic: < 10nm);
- High transmittance in the pass band (> 90%);
- Typical 6 OD Blocking Range: 0.85l0~1.15l0;
- High laser damage threshold (> 20 J/cm2 @ 532nm);
- Superior environmental reliability
Available sizes (mm) :
-
25 dia., 12.5 dia.; 25x25, 16x16, 12.5x12.5, 8x6.5, or customer specific.
