QIs it possible to fabricate user's sample brought to Pulstec?[ NEO-500 ]
AThe system can draw nano-dot on photo-resist or thermal-resist applied surface of the substrate such as Si, glass and polycarbonate. NEO-500 uses the laser lithography technology.
 
QWhat kind of the shape of substrate is supported?[ NEO-500 ]
A Maximum size is up to φ12cm optical disc shape. The system uses air absorption rotational stage to hold the substrate and draw nano-dot in spiral.
 
QHow fast is the processing speed?[ NEO-500 ]
AThe spindle can rotate at 10,000 rpm. For example, it takes 10 minutes to draw nano-dot pattern, with 1.5um interval which is similar to photonic crystal structure, on the 2 inches wafer.
 
QWhat kind of application is the system used for?[ NEO-500 ]
AOptical device such as anti-reflective structure and wavelength plate, next-generation hard disc, next-generation memory, and element sensing chip.
 
QWhat are the features of TDS?[ 3D Scanner ]
ATDS series is implemented with FPC (field power control) function.
Without spraying, TDS series can obtain the data from the black colored and burnish objects which are generally difficult to be measured with laser.
Data can be obtained even if there are many colors in the measurement area.
Because it can be used outside, it is used for archaeological dig.
 
QHow wide is the the scanning area?[ 3D Scanner ]
AField of view and resolution level depend on a scanner type.
We have several types of scanners designed for various application purpose.
Our product lineup starts with the narrow range type (for the cm order area), up to the wide range type (covers the angle of 360 degree).
Our product lineup covers from high resolution measurement with close-up focus to wide range measurement at distant view.
 
QWhat kind of data can be scanned?[ 3D Scanner ]
AMany kinds of materials can be scanned. For example, automotive parts (such as sheet metal product, metal foundry), plastic, rubber, papers, human skins, plants, dirt, rocks, wood, concrete, glass, potteries, iron, etc.
High resolution model can obtain the data from fingerprint, wrinkle on the skin, concavity and convexity of words on the coins, etc.
 
QIs there any object the data cannot be measured?[ 3D Scanner ]
AHigh reflectivity objects such as mirrors cannot be measured because TDS analyzes the scattered beam.
It is also difficult to scan the transparent materials such as glass, water surface, etc.
 
QIs data accuracy checked?[ 3D Scanner ]
AWe inspect the accuracy of all scanners before the shipment.
Each scanner is inspected by the test equipment certified by the Japan Quality Assurance Organization (JQA). e.g.) variation of weighted center and flat surface tolerance.
 
QWhat is the speed of scanning? [ 3D Scanner ]
A•TDS series
Area scan typically takes from 2.4 to 15.4sec, while line scan takes from 0.024 to 0.055sec. Multiple scanning mode is available from ''high speed scanning'' to ''high density scanning''.
•FCAN
It takes only about 1second to obtain high-accuracy 3D data.
 
QIs it possible to obtain color data with 3D data?[ 3D Scanner ]
AFSCAN can obtain 3D data and color data at the same time.
However, it is impossible to do the same thing with TDS series, because TDS uses laser scanning method.
So, it is necessary to obtain the color data independently and apply to the 3D data by image processing.
 
QWhat is the method and feature?[ Wavefront Sensor ]
AShack-Hartmann method is used for PWS-1000. The features of this method are as following; compact in size, real time measurement, high dynamic range, and strong to vibration. It does not have any influence from the interferometer and is able to measure with more than one wavelength.
 
 
QWhat is the system structure? [ Wavefront Sensor ]
APWS-1000 is consisted of wavefront sensor, measurement software, IEEE 1394 cable for connection. If you have PC with IEEE 1394 interface (6 pins), you can start measuring right away. You can also purchase PC from us.
 
 
QHow do you calibrate? [ Wavefront Sensor ]
AWe recommend our LD Reference Diode Laser Source (Wavelength:405nm/655nm/780nm) which is proven calibration laser source for interferometer.
We will attach a calibration data in your desired wavelength on sending. Also, on-site calibration service is available for regular check.
 
 
QWhat is your recommended PC specification? [ Wavefront Sensor ]
A
