Laser Controller C158 comes with integrated temperature driver and laser driver in one package. Temperature control is fully linear and has capability to use separate power supply for laser TEC. TEC control can be done via built-in PI loop or external signal. Laser driver has analog bandwidth of 250 kHz and separate fast TTL compatible switching provided via SMB connector. Laser current has a hardware limit of 250 mA which cannot be exceeded in any case.
