Precision Spatial Filter 990-1000 filters the beam from any low power, visible to near infrared laser. The result – the output beam is delivered with a smooth, near ideal intensity profile. The Spatial Filter consists of two YZ Positioners 990-0100 and Translation Stage 860-0060-04SF (modification of 860-0060-04). YZ Positioners for Lens, Pinholes and Objectives 990-0100 provides adjustments of the pinhole and objective in two axes. Precision X axis motion is provided by Translation Stage 860-0060-04SF. The pinhole and the objective should be selected and ordered separately. Provided selection of interchangeable microscope objective lenses and precision pinholes, allow you to build the best spatial filter for your laser.
