Inspection of electronic / precision components High-speed imaging 350 μ m Components Circuit board 240 μ m 0 μ m Eliminates the need for focus adjustment, thus achieving effective inspection. Example: Semiconductor flaw inspection Printed circuitry ・ Inspection time for electronic and precision parts, etc., needs to be reduced. ・ Equipment costs need to be reduced. P r o b l e m ・ A large depth of focus even in a high-magnification observat i on e l iminates the need for focus adjustment, improving the inspection efficiency. ・ Eliminates the use of a mechanical auto focus drive unit, achieving cost saving of inspection devices. S o l u t i o n ・EDOF・Auto Focus ・Multi Focus・Focus Stacking・TAGLENS-3D Proposed Functions The high-speed shooting of a costly crash test is successfully completed at one try thanks to a large depth of focus. Example: Crash test ・ Instantaneous shooting of a crash test results in defocusing of scattered chips. ・ Completion with a single trial is needed because of destructive test. P r o b l e m ・ Allows shooting of deep images at a time, thus capturing all scattered chips. S o l u t i o n ・EDOF・Focus Stacking Proposed Functions

P r o b l e m ・E xcellent focus expansion effects and long scan range. ・ Wide field of view ・ Realizes reduced system costs. S o l u t i o n Machine vision Distant observation is possible with a machine vision lens Example: Inspection of large parts for defects Allows inspection of a workpiece with the camera mounted on a robot arm. Example: Inspection using a robot. ・ It takes time to observe a workpiece from various angles with the camera mounted on a robot arm. P r o b l e m ・ The large depth of focus eliminates the need for focus adjustment and allows observation from various angles, thus contributing to time-saving of observation. S o l u t i o n ・EDOF・Multi Focus・Mixed Image Proposed Functions Absolutely allows observation of target objects with a large depth of focus. Example: Observation of minute bubbles in glass / liquid ・ The 3D positions of particles cannot be captured. ・ The deeply-located particles cannot be focused sharply. ・ Focus on floating matter in liquids is not possible. P r o b l e m ・ Allows all the particles spread in a wide range to come into focus. ・ Enables the 3D positions of spatially-moving particles to be determined from each focusing position. ・TAGLENS can be used in microfluidic channels.

C a p t u r i n g v a r i o u s Z p l a n e s i s n o w p o s s i b l e w i t h o u t m o v i n g p a r t s Up to 20 cross-sectional images at arbitrary heights can be captured simultaneously Until now, imaging of objects with differing heights and depths was performed by taking multiple photographs while moving the camera vertically (Z-axis motion). In contrast, TAGLENS allows simultaneous probing of multiple heights or depths. Moreover, a captured image is displayed in real time. The focus range is variable without changing the camera position D u r i n g n o r m a l f o c u s i n g W h e n u s i n g T A G L E N S Multi Focus EDOF (Extended Depth of Focus) Improve inspection efficiency using TAGLENS with its ultra-wide focus range
