Our optics have best-in-class surface roughness, whether we're talking flats, aspheres, or even freeforms.  That's right.  Super-polished freeforms.  

We've demonstrated exceptional quality using white-light interferometry, laser scanning confocal microscopy, and atomic force microscopy (AFM).   Fused silica (Corning 7980) has surface roughness as low as 0.25 nm RMS.  Other glasses such as N-BK7 (Schott), and newly demonstrated, high index,  Lanthanum flints also exhibit this same low roughness.

Non-rotationally symmetric optics are just one strength of laser-chemical fabrication.  We can fabricate novel shapes limited only by your imagination.  Options include:

• Freeforms
• Aspheres (large spherical departures and "gullwings")
• Cylinders
• Toroids
• Off-axis parabolas
• Lens arrays
• Diffusers
• Phase Masks

The designs can become more radical when we combine distinct optical functions into a single monolithic component—such as hybridizing a freeform surface with a diffuser, or engineering lens arrays with varying focal lengths for individual lenslets.   

By pairing traditional laser machining with chemical fabrication, we streamline downstream assembly. We can directly machine precision datums, fiducials, mounting holes, and alignment grooves into the substrate to simplify assembly. 

We are developing a body of research demonstrating exceptional laser damage resistance.   Independent tests by Spica Technologies and AmeriCOM show no laser damage for high fluences at low wavelengths (320 nm) or for continuous wave irradiation further out in the spectrum (1070 nm).
