AFBR-S20SK-V2 is a slit evaluation kit for Qmini and Qwave with 50µm, 100µm, 150µm and 200µm. The slit evaluation kit includes four different slit diameters integrated in the SMA 905 connectors. With a hexagon socket screw key, you can easily switch the SMA connector with the integrated slit and adjust the optical performance to your application. A smaller slit leads to higher optical resolution but decreases the spectral sensitivity of the device. Changing from a 20µm diameter to a 50µm slit doubles your optical throughput and allows detecting weaker signals.
