Retardation Measurement System RE-100 -OTSUKA ELECTRONICS CO.,LTD.

HOME>Product>Retardation Measurement System RE-100

For low-retardation and optical axis RETS-100

0(zero)nm to low-retardation.

Optical axis and retardation are simultaneously measured.( Less than 0.1sec)

Motor-less system increases repeatability.

Easy-setup, Quick result.

Measure wavelength selectable other than 550nm

Rth, Azimuth angle measurement (Optional)

Using tensile testing machine polarization and photoelasticity are simultaneously measured

Retardation Inspection System RETS-100　　Cell Gap Inspection System RETS series

RE-100 can measure low-retardation and optical axis speedy and accurately with the configured polarizing measure module and transmissive optics. Thanks to its simple optics system and compact size, RE-100 can keep stable performance for durable usage.

ε and γ are calculated with fitting and Fourier transform.
