Description
ImageMaster®Universal Line
The preferred choice of R&D labs around the word
ImageMaster® Universal has been designed to measure a wide range of optical parameters related to almost all typical optical components and lens systems.
Virtually any existing lens systems ranging from high performance photographic lenses to military sighting devices can be accurately measured.
ImageMaster® Universal is modular and upgradeable to allow for custom configuration as test requirements change. The instrument can be configured for testing optical systems with:
object at infinity
object and image at finite conjugates
afocal systems
ImageMaster® Universal is designed to work in different spectral ranges from UV to far IR. High quality optics include specially designed high definition lens collimators and mirror collimators with surface quality up to l/15.

Relay Optics free of residual aberrations
The long co operation of Trioptics with world known companies as Zeiss and Leica resulted in specially selected, high performance objectives manufactured by these companies and used in Trioptics instruments as relay optics.
ImageMaster® Universal incorporates only relay optics with insignificant residual aberrations and with large numerical aperture. The selection of the relay optics is continuously improved, however, some examples often used relay optics:
Zeiss 50XNA0.7, Zeiss 50XNA0.8, Zeiss Apo 50XNA0.95, Leica PL Apo 50XNA0.9.
Perfectly aligned optical heads
An important error source in MTF-Measurement is related to the adjustment and alignment of the measuring head. To avoid any conceivable misalignment or focus error, Trioptics developed a proprietary procedure to perfectly locate the CCD Chip in the focal plane of the tube lens. In a second step the centration of the relay and the tube lens is optimized so that the residual errors of the relay optics are negligible. This highly accurate alignment of the optical head is an essential and distinctive feature of the ImageMaster® Series, ensuring excellent accuracy and repeatability.

Colllimators
TRIOPTICS is offering worldwide the largest range of collimators, autocollimators and accessories. A careful selection of the best collimators and an accurate focus alignment deliver aberration free collimators with a nearly zero departure from collimation. A certificate of calibration of infinity position can be supplied with the collimator.
Depending on the spectral range required for the MTF-Measurement, the ImageMaster® Series are equipped with refractive or mirror collimators.
The TRIOPTICS refractive collimators are mounted in a hard chrome plated tube in order to ensure long term mechanical and thermal stability. The mirror collimators feature highest surface quality, typically λ/10 to λ/15, are made of Zerodur and mounted in a rugged, lightweight Aluminium structure. All collimators provide diffraction-limited performance on-axis

ImageMaster® Compact Line
Fully automated, ultra-accurate, multifunctional MTF-Test Station
ImageMaster® HR is the top instrument of our Compact Line series. It is a modular, upgradeable instrument line able to measure a wide range of optical parameters related to almost all typical optical components and lens systems. Almost unlimited applications and use in laboratory, production or quality control are the outstanding features of ImageMaster® HR.
In order to ensure the most convenient and accurate positioning of the lens mounts, the ImageMaster HR is set up vertically. Moreover, the focusing and field stages are mounted in the bottom side of the instrument. The reference mechanical surface of the sample holder is horizontal, the lenses to be measured can be simply mounted on the holder in a stable position due to the own weight of the samples. Since the large majority of the lenses have the mechanical reference surface on the bottom side, the ImageMaster-HR offers the ideal conditions for easy, stable and accurate positioning of the lenses to be tested.
The motorized rotateable arm is equipped with backlash free transmission gear and an ultra-accurate rotary encoder. The rotateable arm allows for measurement of lenses at large off axis angles: +/-90° and if necessary up to 120°. |

ImageMaster® PRO Line
The leading instrument for testing mobile phone camera lenses.
ImageMaster® PRO is not only the fastest instrument but also the most accurate and the only one providing direct traceability to international standards. In a very short time the ImageMaster® PRO became the industry standard for measurement of mobile phone camera lenses. Over 60 systems installed worldwide prove TRIOPTICS leadership in testing mobile phone and digital camera lenses.
Accurate
The accuracy and repeatability of the measurement depend decisively on the precise alignment of the illuminated target with the sample holder. This chief requirement is optimally solved in the ImageMaster® PRO line by an integrated optical alignment tool for quick alignment and parallel setting of the reticle plane and stages. This alignment tool can be used for initial alignment, periodical check and after exchange of the reticle. The accurate adjustment of the relay lenses mounted on the CCD-cameras of the measuring head is directly influencing the accuracy and repeatability of the system. An ultra accurate proprietary procedure allows to optimize directly the wavefront of the relay lenses and thus ensuring the best and most reliable performance.

Universal
The specific measurement field positions can be continuously adjusted in an extra wide range from 10° to 60°. The field test configuration changes can be accomplished easily, fast and without tools. Provisions are made for measurement of zoom lenses at position WIDE, TELE or BOTH. Not only can the angle field positions be easily set up but the field ratio configuration as well. Field ratio of 1:1, 3:4, 120° and other are covering almost all of the customer requirements.
Fully Automated Operation
Once a lens tray with 30 to 60 lens seats is kinematically placed on an open frame with two translation precision stages the Image-Master® PRO positions each lens on the optical axis of the instruments, performs an accurate focussing, calculates and displays the measurement data and produces a Pass/Fail result.
User oriented design
The instrument is compact and ergonomic, self contained and easily transportable so that can be moved into the production line or in the lab for analysis and optimization. A reduced keyboard - 4 buttons (START, STOP, MEASURE, CUSTOM) or foot switch allows a PC independent operation. The cover of the detection dome with the cameras can be simply swivelled in order to obtain access to the adjustable camera holders. The quick and easy changing of the measurement set up makes the ImageMaster® PRO the ideal measurement tool not only for high volume production but also for laboratory analysis and optimi-sation. |
