MTF Measurement Station
ImageMaster PRO 10
As a result of various improvements the ImageMaster® PRO 10 enables customers to significantally increase their yield. It is the fastest and most accurate MTF measurement system on the market for qualifying mobile phone lenses and other miniature lenses. Besides the new software architecture and functions, the more precise mechanical components lead to best performance in accuracy, reliability and measurement speed. Faster MTF algorithms reduce the test cycle time so that an outstanding throughput is achieved. The ImageMaster® PRO 10 features a 15% increased productivity compared to the ImageMaster® PRO 9.The new ImageMaster® PRO 10 also provides additional measurement functions. For example, measurements at different frequencies and RGB measurements can be performed to determine chromatic aberration. An upgrade of four additional cameras allows the measurement of relative illumination for testing the homogeneous illumination of lenses in the field.

Optical Test Instruments
OptiSpheric® & Spherometer
TRIOPTICS' OptiSpheric® and Spherometer are the classic optical test systems for spherical lenses that can be found in virtually any optical manufacturing process. While the Spherometer is used for the tactile determination of lens radii, OptiSpheric® systems provide contactless measurement of effective focal length, back focal length, flange focal length, MTF on axis and the radius of lenses. Specific upgrades allow determining centration errors and angles on plane surfaces. Systems for testing IOLs in compliance with EN/ISO 11979 form a class of their own. OptiSpheric® IOL R&D is preferably used for measuring single lenses while OptiSpheric® IOL PRO 2 is designed for the fully automated IOL measurement in serial production.

SINE Sinusoidal Vision Demonstration Array
The Sinusoidal Visual Demonstration Array is designed to demonstrate the Modulation Transfer Function (MTF) of the human eye. Its transmittance varies sinusoidally and increases in spatial frequency from 0.2 to 20 c/mm, following a logrithmic scale. The modulation increases linearly from top to bottom. One can see, in the image, where the visual contrast contour disappears which is the MTF of the eye. Ideally suited for teaching and demonstration, the Array is available on film mounted in glass (-G), or mounted in a 2″x 2″ projection slide.(-SL)

wavefront sensor
HASO3 FAST
Our HASO3 Fast Shack-Hartmann wavefront sensors provide fast accurate and reliable measurements by uniting the standard HASO family's standard functionalities that customers have come to rely on, including absolute measurement, unequalled accuracy and insensitivity to vibration, with an acquisition speed of 905 Hz and a spatial resolution of 14 x 14 microlenses.When coupled with our HASOv3 software package, you can perform both zonal and modal wavefront reconstruction; calculate the PSF*, MTF* and Strehl ratio*; visualize the spot diagram; and obtain the M* parameter. Adaptive optics users can take advantage of our CASAO software package to control adaptive optics loops to compensate for atmospheric turbulence, optimize the focal spots of laser beams and Freespace communications.

SINE Sinusoidal Single Frequency Gratings
Our SINE Sinusoidal Single Frequency transmittance patterns have proved to be very useful for specialized MTF Measurement as well as for such applications as moirè contouring. They are made on film base material with a nominal thickness of 0.175mm. This material is polyester and tends to be somewhat birefringent. The harmonic modulation values are generally 3% or less.

SINE (Sinusoidal) Targets & Arrays
Sinusoidal Target Arrays have been recognized as a superior test method for a variety of applications, from moiré contouring to reliable MTF Evaluation of materials, lenses, cameras, and electro-optical systems (Follow the hyperlink to learn about using Sinusoids for MTF eval). Sinusoidal Pattern Arrays are manufactured on two different materials for both reflective and transmissive applications. Because of the inherent limitations of reflective materials, the maximum spatial frequency of the reflective pattern arrays is limited to 20 cycles per mm, while the transmission film arrays are offered in various sizes up to 256 cycles per mm. In addition, the sinusoidal arrays are available in a Single Frequency Grating or with Multi-Frequency Gratings. If instead of continuous sinusoidal frequency, you are looking for a square wave frequency design, then look to the Ronchi Gratings page. Should you need to alter the size of the pattern or the substrate, fill out our Custom Test Targets and Charts form and start the conversation.

SINE FBI Charts
There are two SINE Sinusoidal arrays designed for FBI applications: the SINE M-13-60-S-RM and the SINE M-13-60-FBI Kit.The SINE M-13-60-S-RM was designed jointly by the Federal Bureau of Investigation, of Washington DC, and MITRE, of Bedford MA. The primary function of this Target is for computing Modulation Transfer Function (MTF) evaluation in live scanner fingerprint systems for conformance to Integrated Automated Fingerprint Identification Systems (AFIS) image quality requirements. The array is on reflective material measuring 16mm x 16mm with sinusoidal arrays ranging in frequency from 1.0 to 10.0 cycles per mm; with nominal modulation of the sinusoidal areas at 60%. The top and bottom rows are density scales, from 0.20 to 1.20 densities.The SINE M-13-60-FBI Kit consist of two individual components, the SINE M-13-60-1X-RM and the RR1-N-RM Ronchi Ruling grating.
