Collimators and Mounts

The new ranges of Tube Collimators and Precision Mounts from Optical Surfaces have been shown at the recent Laser 2003. Compact in design, the collimators are based on the company's ultra-high precision off-axis paraboloids using zero expansion to ensure long term stability. Constructed in aluminium with matt black walls, the units can be supplied athermalised to suit a wide variety of conditions. All optics are prealigned in stress-free mounts. The combined optical performance being better than lambda / 5 p-v at 633 nm wavefront in the field centre. The range is transportable from site to site whilst maintaining alignment. The new range of precision mounts provide a secure and stable platform for off-axis, spherical or flat mirrors up to 250 mm in diameter.
