Making optics with high laser damage threshold requires a comprehensive approach to process design and control. We invest into both R&D and special equipment to provide our customers with state of the art products.
Our unique capabilities derive from a core competency in aspheric optics and strategic relationships with Okamoto Optics Works of Yokohama Japan and Plymouth Grating Laboratory. We access special resources available at Okamoto Optics such as a 4.3m polishing machines and a 2-meter electron beam coating chamber with IAD (Ion Assisted Deposition).
We complement these special capabilities with robotic optics polishing plus systems design and integration. Our technology and insight enable us to optimize laser damage threshold while also controlling film stress and wavefront quality. This is critical to producing optics that maintain wavefront stability and film integrity in vacuum environments.
Our OAPs are used in the best laser labs around the world and we make more OAPs than any other product. What makes our OAPs special is our unique way to control quality – focused on the way you use optics! We’ve consulted with laser engineers and scientists all over the world to develop specifications that optimize focal spot density and diffraction in the image plane. We make this easy for you by defining three special quality grades; High Performance, Precision, and Standard.
High Performance Grade: This is the state of the art. Reflected wavefront error is controlled to λ/50 rms. Diffracted features in the image plane such as satellite focii rings and scatter are < 10-6 in intensity compared with the central focus maxima. We also provide and industry leading envelope fuction over the PSD to control amplitudes of mid-spatial frequency errors. The result is a focusing performance that will optimize the results of your beam line.
Precision Grade: This is the most popular grade. Reflected wavefront error is controlled to λ/20 rms. We also provide and industry leading envelope function over the PSD to control amplitudes of mid-spatial frequency errors. Precision grade is the best combination of great performance and affordable price.
Standard Grade: Standard grade provides you with reflected wavefront error < λ/10 rms. We make standard grade OAPs with the same production equipment and staff as Precision and High Performance – but the emphasis is on affordability.
Critical dimensions and specifications may include: Geometry, Focal Length, Conic Constant, and off-Axis Angle.

Our coatings have been tested by Osaka University Institute of Laser Engineering, SPICA, Sandia National Laboratory, Laboratory for Applied Optics (France), Ohio State University, and CEA.
Coatings are available for 526-nm, 1054-nm and broadband coatings for center wavelengths at either 800 or 900 nm. Our OOW-HRV-800-45 design provides nearly 200-nm of bandwidth.
