Until now, the company has been offering integrated mirror devices ranging from 0.8mm to 1.7mm in diameter, and bonded mirrors from 0.8mm to 3.6mm in diameter. Mirrorcle’s bonded MEMS mirror devices are modular in design, consisting of an actuator ‘engine’ and a mirror of customer-selected size. With a variety of different MEMS actuators, a selection of aluminum or gold mirror coating, and a selection of mirror sizes and shapes, customers are given a wide range of choices to match their varied application requirements.

Modular MEMS design allows devices to be tailored to customers’ application requirements.

Larger mirrors obtain slower characteristics than smaller ones. In addition to slower point to point responses, larger mirrors could be more susceptible to environmental shock and vibration. Because of the company’s insistence on providing high reliability products with adequate speeds, Mirrorcle Technologies has offered mirror sizes up to 3.6mm and strongly recommended that the largest mirrors be matched with largest actuators in customers’ applications. For applications that do not require large scan-angles, stiffer actuators are available in all sizes, offering greater speeds than those that offer larger tip/tilt angles.  Therefore good speed and immunity to shock and vibration can be obtained in all actuator and mirror sizes, provided proper matching of their properties. Based on customers’ demand for ever larger mirror sizes, and with continued improvements in actuator designs and performance, the company’s regular off-the-shelf offerings now also include a 4.2mm diameter mirror. All bonded mirrors of sizes 1.6mm, 2.0mm, 2.4mm, 3.0mm, 3.6mm, and 4.2mm are now available in any quantity and with either Gold or Aluminum coating. Just like the smaller bonded varieties, this mirror can be mounted on a variety of MTI actuators, and may be ordered in a selection of different packages, ranging from large 24-pin Dual-in-Line (DIP24) to LCCs of different sizes.

Mirrorcle Technologies has a track record of successfully realizing large mirror sizes upon customer demand, up to a 9.0mm diameter device that was showcased at the MTI booth at the recent SPIE Photonics West exhibition. Those, special sizes outside of the company’s regular offering, are suitable for use with lowest angle actuators of -1° to +1° of mechanical tip/tilt. With regular sizes of up to 4.2mm, standard mechanical tip/tilt angle range is up to -5° to +5° on both axis.
