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.
