PixeLINK USB 3.0. USB 2.0, FireWire, and GigE industrial cameras can be adapted to fit OEM application requirements whether they are simple or complex.

Our diffractive test lenses are particularly suitable for testing large surfaces with large radii of curvature. For precision measurement of cylindrical and spherical surfaces, we offer CGHs with an integrated Fizeau reference surface named diffractive transmission cylinders (DTC), or diffractive transmission spheres (DTS), respectively. Testing of concave and convex surfaces is equally possible. This allows cylindrical and spherical lenses to be tested with high precision.

Simple adjustment, installation, and measurement in just a few steps: Our alignment holograms and focus beams facilitate quick and easy alignment of the test specimen. Our alignment beams can also be used to probe markers and fiducials on the optomechanics.

Optical Meters are benchtop or handheld instruments used to measure properties of light like power, energy, or wavelength.

Our CGHs are individually designed for your testing application and manufactured to the highest quality standards (ISO 9001:2015). This means that almost any optical surface can be tested. Testing of aspherical diffractive optics is also possible.

The innovative method of interferometric precision alignment allows optical system alignment to be adjusted with an accuracy of a few micrometers. The individual optical components are aligned with pinpoint accuracy based on the multi-zone CGHs calculated individually for each system. Even systems whose detection spectrum lies far outside of the visible regime (e.g., radio telescopes) or whose operating conditions cannot be easily reproduced during production (e.g., temperature in space telescopes) can be adjusted with the same accuracy.

Our diffractive null lenses (DNL) are ideal reference optics for measuring aspherical or cylindrical optical surfaces. Testing free-form surfaces or aspheric-diffractive lenses is also no problem. By combining the CGHs with a spherical interferometer objective (transmission sphere, TS), almost any surface geometry and the overall performance of optical systems can be tested. Based on CGHs, we offer you test lenses for spherical and aspherical metrology.

Coherent power meter

We have more than 20 years of experience in the field of computer-generated holograms (CGHs) . We calculate diffractive optics for the metrology of aspheres, spheres, cylinders or free-form surfaces. We create CGHs for a wide range of applications and all types of optical glasses, metals and crystals. The more demanding your project, the more interesting it is for us.

CGHs generate almost any wavefront and expand the possibilities of the interferometer for testing form deviations of any optical surface. They also provide optimum results for the alignment of optical elements and testing of lens centration. Our experts calculate the diffractive optics of the CGHs so specifically that the plane wave emitted by the interferometer is converted into a wavefront that is individually adapted to the test task.

Our designs undergo a comprehensive review process. From the initial concept to completion, feasibility, ghost images of other diffraction orders, tolerance analysis, and “as-built” performance are considered at every stage. Each CGH is assigned a unique design and manufacturing report.
