The KV-202 Bench top vacuum ultraviolet spectrophotometer has achieved compactness, high resolution and high stability compared to the conventional vacuum compatible type by using our original nitrogen purge type monochromator (KV-200). Light from a deuterium lamp that emits ultraviolet light is incident on a monochromator via a condensing system, is separated by a diffraction grating, and monochromatic light is extracted. The extracted monochromatic light is split into two light paths, one of which is detected as a monitor for compensating for changes in the light source, and the other is used for a semi-double beam method that irrdiates the sample, enabling highly stable transmittance spectrum measurement.
