Double-beam, double monochromator with PMT detector for high photometric linearity and wavelength range 187 to 900 nm.
The new V-760 series double beam, double monochromator optical design with lowest stray light offers a high absorbance linearity across the wide photometric range. JASCO V-760 can measure up to 6 Abs across UV-Visible region. Variable slit widths provide spectral bandwidth settings down to 0.1 nm with special height slits to further reduce stray light.
Step-scan is a very useful tool for accurate measurement of samples such as bandpass filters for which the transmittance changes significantly over a narrow wavelength range.
