High-Quality Applications for Precise Measurements

Measuring Binocular Quality

This application note describes measurement results of two commercially available 8X/32 sport optics. After measuring with a 530 nanometer (green) light RL (Return Loss) module, we report the transmitted wavefront error and achieved Strehl ratio.

Assembled Lens Testing

This application presents advantages of Shack-Hartmann technology in optimizing and measuring assembled lenses. Featuring a choice of several operating wavelengths within a single instrument, the 2X Pass offers wavelength agility unmatched by interferometers and autocollimator products. Fast measurement speed of 1 to 50 Hz and a large dynamic range of more than 100 waves enables rapid convergence of lens optimization using Modular Transfer Function (MTF), Zernike bar plots, and Seidel aberration polar plots through 360-degree rotation and off-axis measurement up to 50 degrees.

Camera Lens Testing

This application describes measurement of a 50 mm focal length camera lens at various lens speeds. An example of an infinity corrected configuration, wavefront, MTF, and Strehl ratios are reported at several apertures ranging from f/1.8 to f/4. Standard wavefront sensors are available for the UV visible-NIR, and infrared spectrum.

Qualifying Optical Tooling

Single-point diamond turning is heavily utilized when manufacturing contact and intraocular lenses (IOL) either directly or in the successive processes of producing tools, molds, and lenses. This application note describe instruments for measurement of spherical, toric, and aspheric surfaces.
