Custom Optical Mirrors

Surface Finish Gold, Aluminium; Mirror Size 2.5x3.6, 16x11 mm; Tilt Angle ±1.5°, ±5°; Reflectivity 95%, 98%; Max. Actuation Current 60, 200 mA Sercalo Microtechnology’s MM series of miniature MEMS magnetic actuated mirrors and deflection units are used for advanced optical beam steering and pointing. These MEMS micromirrors offer large surface areas and are best suited in applications requiring DC pointing together with dynamic scanning. Using magnetic actuation, the 2D micromirrors’ deflection angle is set linearly with the driving current. They are designed for DC operation as well as scanning and can be used for static or dynamic beam steering with a large surface area of up to 16 x 11 mm and up to ±5° deflection. MM2536-2 dual-axes MEMS magnetic micromirrors with gold or aluminium surface finish are operated in open loop and are currently available with a mirror that has a reflective surface of 2.5 x 3.6 mm. These MEMS micromirrors are best suited in beam steering and scanning applications where small size and low power consumption are important. MM-160110-2 fine-pointing dual-axes MEMS magnetic micromirrors have a large reflective surface of 16 mm x11 mm with gold or aluminium surface finish. As an option, the devices can include an internal optical feedback sensor for closed loop operation.

Max. Actuation Voltage 70 V; Package TO46, TO5; Reflectivity 95%; Mirror Size 1 mm to 2.5 mm; Tilt Angle ±2.5° to ±4.5° Electrostatic driven MEMS mirrors are used in applications where a high pointing stability is required. The electrostatic drive has superior DC performance and is the solution of choice for advanced fiber optic light processing such as in MEMS variable optical attenuators, fiber optic switches and tunable optical filters. Mirror diameters range from 0.8 mm up to 2.5 x 2.0 mm. The Sercalo MEMS 3D mirrors are used for precise optical beam steering. To avoid an optical feedback loop, the micromirror is designed to minimize effects such as drift, hysteresis and temperature dependent performance. The angle is set using electrostatic actuation. Key Features: Low Drift Two Independent Axes Continuous Tilting Single Mirror 1 mm Diameter Mirror High Fill Factor Applications: Optical Beam Steering; Reconfigurable Add-Drop Multiplexer; Vibration Control in Free Space Optics; Optical Processor
