spatial filter

A spatial filter can perform spatial filtering on an incident laser beam. Obtain a uniform emission spot. The microscope objective (see GCO-21) is used to focus laser beams. The adjustment in the z-direction is completed through a guide rail with a clearance reducing micro wire rod. The standard configuration includes four pinholes and a 40x/0.65 microscope objective. Special accessories can also be provided according to customers' needs for different magnifications of the objective (refer to GCO-21). Can be used in conjunction with the adjustable frame series.
