Biomedical

Ophthalmic

4D has custom engineered systems to aid in the production measurement of contact lenses and lens molds.

Accurate measurement of radius of curvature and optical thickness ensures adherence to prescription for proper fit and correction.

in vivo Measurement

4D PhaseCam interferometers aid in the measurement of the corneal surface and the thickness and variation in the tear film. The unique instruments aid researchers in studying eye responses to help improve vision correction and to understand complex eye mechanisms.

Added Technical Resources

Measurement of Space Optics and Structures

This paper presents an overview of the techniques and configurations used to build dynamic interferometers and measurement results for a variety of space-based optical components.

Vibrational Characteristics of Light-weight Mirrors

We present a technique to characterize and quantitatively measure the vibrational mode shapes and amplitudes of mirrors concurrently with surface figure testing..

Products for Semiconductor

AccuFiz SIS

Measures both sides of transparent, parallel optics as thin as 200 microns, surfaces in multi-surface optical systems, remote cavity test setups, and solid cavities such as etalons (laser rods).

Optical Profilers

NanoCam Sq  systems measure surface roughness on coated and uncoated flats to ensure the quality of polishing processes.
