Notes:
1) The diffuse window reduces the positioning accuracy requirements and increases the damage threshold at the cost of a reduced sensitivity by a factor of approx. three to five. Recommended for high peak power lasers only.
2) This model has negative output. All other models have positive output by default but may be ordered with negative output if required.
3) With TEC cooling module, non-standard housing.
4) Modified material with increased blue / UV sensitivity.
5) Not compatible with the optional filter holder.
6) Greatly improved performance.
