The Ophir BeamStar CCD beam profiler provides all you need for beam profiles of both pulsed and CW lasers from mW to Watts. The system comes with the camera, filters, PC card, software and detailed instructions.

The BeamStar has hardware and software features so it can handle pulsed lasers seamlessly. Even slowly pulsing lasers which give most beam profilers problems are easily handled by the BeamStar which has a threshold function so only frames above the preset threshold will be displayed.

The BeamStar comes with a set of filters which can easily be mounted and dismounted from the camera. The filter combinations together with the built in gain and shutter control allow a dynamic range of > 10^11 : 1 It also has an exclusive feature where you can look at the center of the beam with low sensitivity and the edges of the beam with high sensitivity thus giving a much higher dynamic range than before.

The BeamStar is available with the BeamStar U range extender/beam reducer. This is a reducing telescope which both reduces the beam by 4x, allowing beams up to 30mm across to be viewed and sensitizes the camera to the UV spectral range from 193 to 266nm. The telescope can also be used for the spectral range 320 - 1100nm with additional filters.

The BeamStar-1500 has a phosphor coating which in addition to the regular spectral range of 350-1100nm, is also sensitive to 1500-1600nm and somewhat sensitive to 1300nm.

A 4X beam expander is available for the BeamStar and BeamStar-1500 enabling the user to image a source, such as a laser focal spot, from 8mm in front of the expander onto the CCD while at the same time expanding it 4X.
