Moving Mirrors for Tunable Lasers
The scanning two axis tilt mirror is an important technology that can be used in many industries. Two axis scanning allows these mirrors to have a full 360° of rotation at up to a 3° tilt angle. There are several major benefits of the MEMS Optical tilt mirror over competing products.

Benefits

  • The tilt angle is analog as opposed to on-off. In other words, if a tilt angle of 1.79° is required, it is simply a matter of applying the correct voltage and that angle (or any other angle) can be obtained.
  • There are no holes in the mirror surface. Most competing products have holes in the mirror surface as a result of processing requirements. Due to the advanced processing technology used, MEMS Optical tilt mirrors have no holes in the mirror surface, allowing for full reflection of all impinging light.
  • Low voltages are required for actuation. Many competing products require 200 volts or more for actuation. A total of less than 120 volts is required for the full 3° of tilt and less voltage is required for less tilt. Clearly, these mirrors have set a new standard in the industry.
