- Precision Optics
- Quality Mechanics
- User Friendly
- Simple Setup
- Low cost
Tower’s new BeamEx1000 provides a low cost solution to expanding the capability of a standard 4″ Fizeau Interferometer to measure up to 6″ optics. The BeamEx 1000 mounts to the front of a standard interferometer using the industry standard bayonet mount.
The combination of the BeamEx1000 and the interferometer provides for testing of very precise optical surfaces.
The BeamEx1000 also provides an adjustable tip and tilt capability incorporated with a 6″ bayonet mounting to accommodate a suitable transmission flat, a reference flat or a transmission sphere.
Tower offers as an option a 6″ Transmission Flat which snaps into the Beam Ex 1000.
The 6″ flat has a surface error of λ/20 and is AR coated for 632.8nm.
