Two versions are available for each wavelength range:
- The high power versions have an active area of 40x52mm and can be used with laser powers of up to 120W/cm2 for 1.5-5µm and 50W/cm2 for 5-20µm.
- The high power/low power versions have two active areas, each of which measures 40x25mm. The high-power side is identical to that above, while the low-power side is designed for powers up to 8W/cm2.
