NEW Transmission Spheres, 4-inch and 6-inch

These spheres, manufactured by a leading optical company in the USA, are available as Lambda/10 or Lambda/20. Some have an “extended” reference surface radius. All are in a metal mounting cell, just like a Zygo®, Veeco (Wyko), ESDI or ADE-PST transmission sphere. Includes storage box. Delivery is 10 – 12 weeks, possibly better if we are in a build cycle.

NEW  |  CaliBall™

If you check spherical surfaces using an interferometer you need a CaliBall™ in your shop. This calibration ball is used to determine the residual error in interferometer test optics. Email for detailed technical papers and procedure. CaliBall2 is $1,450 – includes fixture to hold CaliBall in a Zygo mount. Or, original CaliBall at $995.
