Description
Newport 900 Three-Axis Spatial Filter Micrometer Pinhole Optical Breadboard
The Newport 900 is a three-axis micrometer spatial filter designed for precision pinhole alignment and objective lens focusing on optical breadboards and laser tables. It provides independent micrometer-controlled X, Y, and Z adjustment, allowing accurate positioning of the pinhole and objective lens for effective laser beam spatial filtering and wavefront cleanup.
Specifications & What's Included
- Manufacturer: Newport Corporation
- Model: 900
- Type: Three-Axis Micrometer Spatial Filter
- X-Y axes: Non-rotating micrometer spindles with magnetic pinhole mount registration
- Pinhole mount: Magnetically registered against precision-machined spindle faces; slotted interface resists accidental displacement
- Z-axis (focus): Precision linear bearing drive — long travel, no jitter or side-play
- Long-travel Z-axis accommodates a wide range of objective lens focal lengths
- Open architecture body for easy pinhole and objective swapping
- Black anodized aluminum body with breadboard-compatible mounting base
- Includes: Spatial filter positioner only
- Not included: Pinholes and objective lenses (sold separately)
Applications
Spatial filters are standard components in laser optics setups where a clean, diffraction-limited Gaussian beam profile is needed. A focused laser beam is passed through a precision pinhole placed at the focal point of an objective lens; the pinhole blocks scattered light and spatial noise, and the diverging beam beyond the pinhole is recollimated to produce a smooth wavefront. The Newport 900 is well suited for use on optical breadboards and optical tables in research, interferometry, holography, fiber coupling, and laser beam characterization applications. The three-axis micrometer design makes it straightforward to walk the pinhole into alignment without disturbing the Z-focus, which is a common requirement in sensitive optical setups. Newport spatial filters of this type have been a fixture in university and industrial optics labs since the 1980s and remain in active use wherever beam cleanup or spatial mode filtering is required.
This Newport 900 Three-Axis Spatial Filter was removed from a working laboratory environment and is in good used condition. The anodized black body and micrometer spindles show normal handling wear consistent with lab use, with no signs of damage or missing components. The magnetic pinhole mount and all three micrometer adjusters are present and appear intact. Pinholes and objective lenses are not included and are sold separately.
