These mirrors are not made for much of the visible spectrum, but you guys might like this for something. Good reflectivity for red and NIR-IR wavelengths.

Two Axis, Gimbaled Mirror ±5 Degrees Mechanical Rotation One Mirror, mm2 in Area Electromagnetic Actuation Low Voltage Operation Low Optical Insertion Loss (>95% Reflectivity, >5 m Radius of Curvature) High Precision Position Feedback (13-Bit Resolution) High Performance (<5 ms Switch Time) High Reliability Simple Drive Requirements * Tilt Angle Linear with Applied Current Windowless Package * Allows Use in Multiple Light Steering Applications
Trying to find the original price for these was difficult, but I did find this thread: https://www.eevblog.com/forum/chat/l...mirror-devices - Appears they were terribly expensive to buy new but still unable to find the old prices, I saw 150 dollars each at one web site, over 400 at another, so not sure. Greater than 95% reflectivity from 0.65 to 10 micron wavelength, 700 mw max laser input power. Maybe can be used in shorter vis with loss anyway?
