Laser Interferometer Accessory Guide Transmission Flats (TF) Transmission flats measure surface quality or transmitted wavefront of flat surfaces or optics. The 4 and 6-inch flats mount directly onto the corresponding size interferometer or mount. A storage case is included with the 33 mm, 4 in. and 6 in. elements. A quality certificate is included with all elements. ZYGO Number Clear Aperture Operating Wavelength 4 inch, Dynaflect, Ultraflat 4 inch, long radius 6 inch, Dynaflect, Ultraflat Any – uncoated back surface Any – uncoated back surface Any – uncoated back surface Any – uncoated...

Laser Interferometer Accessory Guide Reference Spheres (RS) ZYGO Number 6024-0302-01 * The 25 mm RS has /20 PVr surface quality in the central f/0.65 subaperture. Use an RS with a TS when measuring the transmitted wavefront of spherical optics. Spheres mount onto the Adjustable Mount with a Self Centering Element Holder. A storage case and quality certificate are included with each element. Transmission Spheres (TS) ZYGO Number 6024-0454-11 Transmission spheres measure surface quality or transmitted wavefront of concave or convex surfaces or optics. The spheres mount directly on the...

Laser Interferometer Accessory Guide TS Part Coverage TS Diameter R1 is the radius of the TS reference optic. D1 is the TS clear aperture (R1f/#). D0 is the housing opening diameter. R2 is the maximum measurable convex part radius when part diameter is larger than D0. For best concave test part coverage use a TS with f/# faster (smaller) than part R/# (radius of curvature  diameter). For best convex test part coverage use a TS with f/# faster than part R/#; coverage is limited if the part diameter is larger than the TS clear aperture; if using an attenuation filter, the measurable part...
