Large adjustable optical mount 5LAOM-600 is designed for heavy, large optics up to 600 mm in diameter. Minimum diameter is 500 mm (using additional clips). Angular travel range in azimuth and elevation is 360°, for precise object positioning ±4° adjustment range is provided. The spring loaded drive mechanism ensures smooth and backlash-free motion. To provide full angular travel range motion, position fixing mechanism must be unscrewed with handle, for precise positioning fixing mechanism must be tighten up. Optical mount design allows fixing and positioning optics or other objects with mass up to 150 kg. Vacuum version 5LAOMV-600 available on request.
