31 Jan 2006 OKO Technologies introduces 20-ch piezoelectric linear deformable mirror for femtosecond pulse shaping. OKO introduces 20-ch linear piezoelectric deformable mirror for femtosecond pulse shaping. The mirror has 10x50mm active area, controlled by two rows with 10 actuators each. Actuator pitch is 5 mm. Maximum surface deflection is 8 um, figure difference between adjacent actuators can reach 3 um. The initial figure is slightly spherical. The response time is better than 1 ms. The mirror can be custom coated with dielectrics and metal-dielectrics. The mirror can be supplied with a complete set of control electronics, including 20-ch 400 V amplifier unit and a 20 (40)-ch USB DAC unit (or a 24-ch 8-bit PCI DAC card) for interfacing to a PC.
