Spectrophotometer
ME-UVN2800
UVN2800 Spectrophotometer is a detection instrument used to measure the transmittance, reflectance and absorbance of substances. It supports the determination of the solar light transmittance in the wavelength range from the ultraviolet region to the near infrared region, and the wavelength range is 190-2800 nm.
UVN2800 adopts a unique dual-beam optical design, which can perfectly correct the absorbance change of different sample matrices, so that the sample can be measured stably. It has the advantages of wide testing range, high precision and good stability.

FPP230A
FPP230A is a scanning four-probe resistance tester specially designed for photovoltaic applications. It can quickly and automatically scan samples up to 230mm in size to obtain square resistance/resistivity distribution information at different positions of the sample. The probe head uses ruby bearings to guide the tungsten carbide probe, ensuring high precision and long life. The dynamic test repeatability (close to the real scene) can reach 0.2%, which is the leading level in the industry. The ultra-wide measurement range of 1mΩ~100MΩ can cover most application scenarios, and can be widely used in many fields such as photovoltaics, semiconductors, alloys, and ceramics.
Stylus Profiler
SP200
Adopts contact surface topography measurement, which is a breakthrough development of traditional surface topography measurement. The minimum contact force can reach 1mg, and no special requirements for the reflective properties of the test surface, material type, and material hardness.
Contact Resistance Tester
TLM-STD
Contact resistance is an important aspect to be considered in the optimization of solar cell electrode. The contact resistance is not only related to the contact pattern, but also to the diffusion process and PN Junction formation process. The measurement of contact resistivity can reflect the problems existing in the process of diffusion, electrode formation and PN Junction formation.
There are two test functions can be switched: 1. Contact resistivity test; 2.Finger line resistance.
