This product has made targeted improvements to traditional dial-type strain gauges and digital display strain gauges, improving measurement accuracy and application experience. It has outstanding features such as high measurement accuracy, no need for zero calibration, and green energy saving:
High-precision measurement: This product uses a high-precision absolute angle encoder for measurement, and the measurement accuracy is better than 2nm.
Dual numerical display of LED display: The display window of this product adopts high-definition LED display, which can display the measurement angle and optical path difference value at the same time, and the user can obtain the required data intuitively, making the measurement intuitive and easy to read.
No calibration required for dark field: This product has been precisely calibrated for dark field before leaving the factory. Due to the use of an absolute encoder, the dark field of polarization field is always at the zero angle point, so there is no need for the user to correct the zero point, avoiding the error caused by artificial correction of the dark field.
Green and energy-saving: This product uses a more energy-saving and environmentally friendly LED light source, which can save energy by more than 80% compared with traditional light sources.
Product modular design, ergonomic operation, easy maintenance and repair.
