OptiSpheric Multi-Wave with special reticle changer and multiple relay lenses
OPTISPHERIC®THE INDSTRY'S STANDARD FOR LENS TESTING
OptiSpheric® is a PC-based Optical Test Station designed to accurately measure
the optical parameters of lenses and optical assemblies.
OptiSpheric® is modular and upgradeable. It covers a large range of applications and
provides fast and reliable test results of almost all optical parameters:
* Effective Focal Length (EFL)
* Modulation Transfer Function (MTF)
* Back Focal Length (BFL)
* Radius of Curvature (R)
* Flange Focal Length (FFL)
Being a part of OptiTest® - the world most comprehensive line of optical test instruments -
OptiSpheric® can be easily extended to cover more applications.
The measurement of plano optics, for example, can be achieved by simply adding
some mechanical fixtures and a software module. In this way the wedge angle, mirror tilt angle,
parallelism of windows, filters and plates and many other parameters of plano optics can be
measured quickly and accurately.
MEASUREMENT OF PLANO OPTICS
The addition of a software module-belonging to OptiAngle® (another subsystem of OptiTest)-
and the use of specific mechanical fixtures converts the OptiSpheric to a powerful tool for
angle measurement of:
* wedges and filters
* 90°-prisms
* parallelism of plane plates
* deviation angle through wedges and prisms
* mirror tilt
* alignment of CD-optical heads
* wobble of rotating glass disks
MULTI-WAVELENGTH CAPABILITIES
To respond to industry requirements for providing measurement capabilities at different wavelengths,
TRIOPTICS developed the OptiSpheric® Multi-Wave able to measure almost
all of the optical parameters at different wavelengths. Normally several wavelengths in
visible spectral range are offered, e.g. 400nm, 546nm, 650nm and 780nm.
On request measurement capabilities in near-infrared (NIR) or ultra violet(UV) spectral range are
provided. The multi-wavelength capabilities require a complex instrument design,
a specific adjustment of the instrument and an individual matching of
all instrument components to the wavelengths requested.
Unlike other suppliers TRIOPTICS is providing a real multi-wavelength design and
is offering real multi-wavelength measuring capabilities:
* A special collimator is adjusted such that the reticle for a certain wavelength is
accurately set at the BFL corresponding to the wavelength
* Narrow interference filters are used to precisely select the required wavelength
* The relay lens of the measuring head is selected to optimally cover
the wavelength range requested.
NIR or UV corrected rely lenses are used for regions of
the spectral range outside the visible range
* Special CCD-Cameras, enhanced for the intended spectral range,
provide optimal measurement capabilities
OPTISPHERIC®T透鏡測試的產業標準
OptiSpheric® 是電腦操控的透鏡測試平台, 設計準確的量測透鏡和光學系統的光學特性 . OptiSpheric® 可以模組化和升級. 它包含了廣泛應用範圍和提供各種光學參數快速可靠的測試結果:
* 有效焦距 (EFL)

多波長性能
針對產業需求提供不同波長之量測功能, TRIOPTICS 發展的OptiSpheric® Multi-Wave 不同波長下的所有光學參數. 一般而言提供可見光的數個波長 , e.g. 400nm, 546nm, 650nm 和 780nm. 近紅外 (NIR) 或紫外(UV) 波段依需求提供。
多波長量測功能需要複雜的儀器設計, 特別的儀器調整和個別元件對波長的配合度. 不像其他供應商, TRIOPTICS 提供實際的多波長設計和量測能力：
* 調整特別的準直器讓適用於特定波長的細十字線光罩準確架設在此波長的BFL位置上
* 使用窄頻濾波器來準確選擇波長
* 選擇量測頭的中繼透鏡來最佳化以涵蓋需求波長. 使用校正過的近紅外或紫外中繼透鏡來試用可見光範圍外需求
* 特殊的CCD-Cameras適用延伸的光譜範圍, 提供最佳的量測功能
