Contact Angle Measurement Device (Tensiometer)
Brand / Model: Biolin Scientific Attension Theta Lite
Description: The Biolin Scientific Attension Theta Lite is a high-precision analytical instrument designed for the measurement of contact angle, surface tension, and surface free energy of solid and liquid surfaces. The system is widely used for surface characterization and evaluation of wettability properties of materials.
Operating Principle: The device operates based on the controlled deposition of a liquid droplet onto a solid surface and the acquisition of droplet images using a high-speed digital camera. Contact angle values are calculated from the captured images, while surface tension and surface free energy analyses are performed using different test liquids.

Photoresponse Characterization System
Brand: Fytronix
Description: The Fytronix Photoresponse Characterization System is an advanced measurement system developed for the electrical characterization of photodiodes, photosensors, photodetectors, solar cells, and similar optoelectronic devices. The system enables automatic measurement of current–voltage (I–V) characteristics under dark conditions and various controlled illumination environments.
Operating Principle: The system operates based on the precise application of controlled voltage and current to the test sample and the accurate measurement of the resulting electrical response. Measurements are automatically performed under dark conditions and with light sources of different wavelengths to analyze the photoresponse behavior of the device.
