New Spatial Filter Q-Set saves setup time-Image

The New Spatial Filter Q-Set from Qioptiq is a pre-configured assembly which provides streamlined integration into your optical breadboard setup to provide homogenized intensity distributiion and reduced aberation of laser beams. Laser light is focused by an achromatic lens and transmitted through a pinhole which partially removes  inhomogenities. At the same time, this Q-Set can also be used to generate a point source.

The pinhole with a diameter of 30 µm is mounted into a x-y-Precision Translation Stage with decoupled adjustment axes. The adjustment screws provide a 0.25 mm spindle pitch and a travel of ±1 mm. The lens can be aligned along the z-axis with an accuracy of 1 µm and almost without any play.

The Spatial Filter Q-Set is provided as a pre-configured assembly and contains the following LINOS optomechanical components:

  • (04) G061210000 - Rod 150mm
