LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Used to eliminate spatial non-uniformity of the beam, improve beam quality, and generate standard fundamental mode Gaussian beams
Compatible with various models of precision pinholes, aspheric lenses, and collimating lenses
Compatible with 30 mm coaxial systems and free-space optical paths

The LBTEK spatial filtering system mainly consists of the Z-axis translation mount MFT, displacement adjustment stage TXY1S, and displacement adjustment stage TXY1: 1) The Z-axis translation mount MFT is used to install the focusing lens, which allows for precise focusing. The lens can be selected with the appropriate focal length based on experimental requirements. 2) The displacement adjustment stage TXY1S is used to align the precision pinhole. The pinhole diameter can be selected according to experimental needs. 3) The displacement adjustment stage TXY1 is used to mount the collimating lens, which can also be selected with the appropriate focal length based on experimental requirements. LBTEK offers various types of lenses, such as aspheric lenses and achromatic cemented lenses. Additionally, precision pinholes with diameters ranging from Ø2 μm to Ø100 μm are available. For more details about the system or consultation on component selection, please contact LBTEK technical support.

Spatial Filtering System Mechanical Components

Can generate standard fundamental mode Gaussian beams when combined with optical components and precision pinholes
Compatible with 30 mm coaxial systems and free-space optical paths
Includes optical component mounts and adjustment tools

The spatial filter is ideal for generating standard spatially distributed fundamental mode Gaussian beams. The input end features an MFT Z-axis translation mount that can accommodate a focusing lens. The beam is focused by the lens and passes through a pinhole mounted on the TXY1S displacement adjustment stage. The output end consists of a 1-inch optical component mounting frame TXY1, which allows for centered installation of collimating optical components. The system includes one 30 mm coaxial system alignment plate CT-1 for alignment purposes and one adjustable aperture CSD20 for adjusting the output spot. For detailed products included in the system, please refer to the component list tab. Device selection and calculations can be found in the technical specifications tab. Note: This component does not include optical elements or precision pinholes. You can purchase them separately in the LBTEK Mall.
