LPT-4 Experimental System for LC Electro-Optic Effect

Short Description:

Advantages
1. The instrument guide rail, slider, turntable, etc. are all made of high-strength aluminum alloy, and the upright material is stainless steel. It has the advantages of small size, light weight, and no rust. The turntable is specially designed and can be finely adjusted. The guide rail adopts a dovetail structure, which is well positioned in a straight line during movement and firmly and reliably fixed.
2. Fix the LCD sample with a frame structure, which is firm and aesthetically pleasing; Using terminal posts to power on the sample is convenient and safe.
3. All device accessories used are optical universal accessories (including commonly used optical power meters). In addition to being used for liquid crystal electro-optic effect experiments, they can also be used for optical experiments such as polarization or for measuring the relationship between the operating current and the output light intensity of semiconductor lasers.

Experiments

1. Measure the electro-optic curve of the liquid crystal sample and obtain the electro-optic parameters such as threshold voltage, saturation voltage, contrast, and steepness of the sample.
2. The self equipped digital storage oscilloscope can measure the electro-optical response curve of the liquid crystal sample and obtain the response time of the liquid crystal sample.
3. Used to demonstrate the display principle of the simplest liquid crystal display device (TN-LCD).
4. Partial components can be used for polarized light experiments to verify optical experiments such as Marius’ law.
