Model : 09OTA-NM

Description :

The Optical Transmittance Analyzer contain a spectrometer and a light source. The 09OTA-NM use to measure the filter's transmittance. In addition to measure the full range transmission spectrum, you also can set up a range or single wavelength for analysis.

• Glass or plastic material products
• Optical thin film. i.e. Window film, ITO, Filter (IR-cut, Band Pass etc.)

Software Function

•   Transmission spectrum graph
•   Auto save with auto sequence number function
•   Monitor point setup (up to 10 points)
•   Average transmission calculation (Tavg)
•   Wavelength of T10%、T50% and T90%
•   GO/NG function (single wavelength)
•   Transmission spectrum calibration function
