The "KV-202" is a tabletop vacuum ultraviolet spectrophotometer that uses our proprietary nitrogen purge type spectrometer (KV-200). Light from a deuterium lamp that emits ultraviolet radiation enters the spectrometer through a focusing system, is dispersed by a diffraction grating, and monochromatic light is extracted. The extracted monochromatic light is split into two optical paths; one is detected for monitoring to compensate for changes in the light source. The other employs a semi-double beam method to irradiate the sample, enabling highly stable transmittance spectrum measurements. 【Features】 ■ Transmittance spectrum measurement in the wavelength range of 120 to 300 nm (vacuum ultraviolet region) ■ Achieves high resolution and high stability with the nitrogen purge type spectrometer ■ Suitable for the evaluation of special films and substrates *For more details, please refer to the PDF materials or feel free to contact us.

The "MK-300" is a polychromator that excels in spatial resolution across the entire CCD detection surface, thanks to its newly designed aberration-correcting optical system. By attaching a CCD detector (sold separately), it is suitable for multi-point simultaneous spectral measurements using branched bundle optical fibers, as well as spectral measurements connected to a microscope. It can accommodate up to three diffraction gratings and is equipped with an electronic controller, allowing connection to a PC via USB cable to perform wavelength shifting and diffraction grating switching using the included dedicated software. 【Features】 ■ Imaging spectrometer with a newly designed optical system ■ Can accommodate up to three diffraction gratings ■ Suitable for multi-point simultaneous spectral measurements ■ Ideal for spectral measurements of observed images ■ Also available in a dual detector switching type *For more details, please refer to the PDF document or feel free to contact us.

The "NRI Series" is a device that measures the refractive index of a sample by irradiating it with monochromatic light of arbitrary wavelengths (1 to 14 μm) based on the minimum angle method and measuring the angle of transmitted light relative to the incident light. It can measure a refractive index accuracy of 0.0001, which cannot be obtained by conventional measurement methods. It is suitable for evaluating Ge, Si, ZnSe, KRS-5, chalcogenide glass, and infrared optical thin films used in infrared windows and lenses. 【Features】 ■ High-precision measurement of refractive index (0.0001) in the wavelength range of 1 to 14 μm ■ Equipped with temperature control functionality, allowing measurement of refractive index variations due to temperature changes *For more details, please refer to the PDF document or feel free to contact us.

The "OD-10" is a spectrophotometer capable of measuring optical densities up to OD10, which could not be measured with conventional spectrophotometers. It is suitable for measuring various low transmittance samples such as multilayer membrane filters, high-concentration filters, light-shielding films, and high-concentration solutions. By combining the lock-in amplifier method and photon counting method, high-precision measurements have become possible. 【Features】 ■ Capable of measuring optical densities up to OD10 in the visible light range (wavelengths 350–700nm) ■ Reduces multiple reflected light from the sample and stray light from the device ■ Incident light on the sample is pseudo-parallel light ■ Reduces interference spectra originating from the device *For more details, please refer to the PDF document or feel free to contact us.

The "VC-250" is a device used to measure the spectral characteristics (spectral sensitivity and spectral response) of photoelectric conversion elements such as photodiodes and CCD/CMOS image sensors. It monitors the light intensity at each wavelength in real-time and, through our unique control mechanism, allows for the irradiation of monochromatic light at a constant energy (W/cm²) and photon count (photon/cm²) for each wavelength. It has a proven track record under the name of spectral response measurement device and is recognized as an industry standard. 【Features】 ■ Well-suited for evaluating the spectral characteristics of photodiodes and CCD/CMOS image sensors ■ Capable of varying the intensity of monochromatic light by up to three digits ■ Easily measure spectral characteristics (spectral sensitivity and spectral response) by simply selecting the set energy or photon count through software ■ Supports external control mode *For more details, please refer to the PDF document or feel free to contact us.
