2d0bb5108c309315d965a9c8cbe8019c_1564637350_4755.jpg


This versatile, customized optical instrument enables one to measure the response time of PDLC(polymer dispersed liquid crystal) at a designated wavelength, transmission spectra and reflection spectra, while the electric field is being applied on the PDLC cell. Sample holder as well as the detector module can be rotated such that the angle of incidence can be adjusted from 0 to +-90 degrees. Contrast ratio is easily derived.




◈ PERFORMANCE


     1.Wavelength range : 380 – 850 nm
     2.Beam spot size : 4 mm
     3.Response time (at single Wavelength) : 0.1 ms
     4.Detector : Multichannel Spectrophotometer
     5.Rotation stage : 0 ~ 180°
     6.Angle of light receive : 0 ~ ±90°




◈ APPLICATION

Response time of PDLC, Contrast ratio, Incident Angle Resolved Transmittance and Reflectance Spectrum, LCD & PDP panel characterization.
