Spatial filters eliminate distorted laser wavefronts and noise to emit clean spherical waves for beams. Used in optical systems such as interferometers and holograms where wavefront quality is critical.

◦A well corrected achromat in the output beam of the spatial filter can be used to collimate the filtered beam.
◦The translation stage and two-axis pinhole allows the light through the objective lens to have good reproducibility..
◦Designed with an emphasis on stability, beam movement during adjustment is minimal.
◦A PA-25 (hole diameter 25μm) pinhole is included. Pinholes can be changed to match the diameter of the laser spot.
◦A Coarse/fine pinhole adjustment (SFB-16DMRO) is also available.
◦To meet a variety of requirements, the mounting position of the objective lens can be changed, allowing objective lenses with different magnifications to be used.

SFB-16RO-N and SFB-16DMRO-N (commonly called as M6 type) and SFB-16RO-UU and SFB-16DMRO-UU (commonly called as Inch type) are of the types in which rods are eliminated from SFB-16RO and SFB-16DMRO.
▶Pinholes can be replaced with different diameter pinholes. Pinhole diameters can be specified at the time of purchase. When changing pinhole diameter, change the number “-25” at the end of the part number to the desired pinhole size in microns.
▶Post length can be changed by specifying the post length when you place an order. We may charge the difference in price depending on the length. Contact our Sales Division for more information.

Attention

▶The type of objective lens and pin hole diameter depends on laser wavelength and incident beam diameter. Technical Note
▶Our Sales Division will gladly help you choose the correct combination also.
▶The unstamped side of the pinhole should touch the retaining ring side. The pinhole maybe not work correctly if mounted incorrectly.
▶We do not recommend using spatial filters for high-power lasers, pulsed lasers, or ultraviolet lasers. Lasers in the near infrared region will have poor transmittance.
▶Objectives should be unscrewed before swapping out pinholes.
