Transmission Sphere enhances interferometer operation.September 30, 2008 -
UltraSphere (λ/50) is designed to enable surface form metrology with uncertainty in RMS of less than or equal to 3.2 nm (λ/200 at 633 nm) when used with Zygo laser Fizeau interferometer systems. Suited for metrology of test optics with greater than 40% reflectivity, this uncoated transmission sphere is available in 4 in. aperture size with f/numbers of f/0.75, f/1.5, and f/3.3.

NEW Zygo Transmission Spheres
Zygo Corporation have introduced the NEW UltraSphere (λ/50) Transmission Sphere to enhance its range of transmission spheres for its laser Fizeau interferometer systems.
The range includes:
Standard Performance (λ/10) Transmission Spheres in 25mm, 4 inch and 6 inch Entrance Beam Diameters (interferometer apertures).
Standard Performance DynaFlect (λ/10) Transmission Spheres in 4 inch Entrance Beam Diameter (interferometer aperture).
DynaFlect Coated Transmission Spheres are best for metrology of test optics with > 40% reflectivity.
High Performance (λ/20) Transmission Spheres in 4 inch Entrance Beam Diameter (interferometer aperture).
The new Zygo UltraSphere (λ/50) Transmission Sphere product is designed to enable surface form metrology with an uncertainty in the RMS) of less than or equal to 3.2 nm (λ/200 at 633nm) when used with a Zygo interferometer. The UltraSphere is an uncoated transmission sphere. Like the Standard and High Performance transmission spheres, the UltraSphere range is best for metrology of test optics with less than or equal to 40% reflectivity.
The new Zygo UltraSphere (λ/50) is available in 4 inch aperture size with f/numbers of f/0.75, f/1.5 and f/3.3.
