Спектрофотометр UV-3600 Plus
Incorporating the latest technology to achieve high sensitivity, high resolution, and an ultra-low stray light level, leading the way to new solutions
Shimadzu developed the world’s first UV-VIS-NIR spectrophotometer with three detectors, consisting of a PMT (photomultiplier tube) for the ultraviolet and visible regions and InGaAs and cooled PbS detectors for the near-infrared region. With conventional instruments that use only PMT and PbS detectors, there is a drop in sensitivity in the crossover region between those detectors. Using an InGaAs detector to cover this crossover region, however, ensures high sensitivity across the entire measured wavelength range, and gives a noise level of 0.00003 Abs at 1500 nm. In addition to the main UV-3600 Plus unit, the Multi-purpose large-sample compartment and the Integrating sphere attachment also feature three detector, enabling the high-sensitivity measurement of solid samples.
High Resolution, Ultra-Low Stray-Light, and Wide Wavelength Range
A high-performance double monochromator makes it possible to attain an ultra-low stray-light level (0.00005 % max. at 340 nm) with a high resolution (maximum resolution: 0.1 nm). The wide wavelength range of 185 to 3,300 nm enables measurement across the ultraviolet, visible, and near-infrared regions. This instrument can perform spectrophotometry for a variety of applications.
Wide Range of Optional Accessories
The three-detector Multi-purpose large-sample compartment or Integrating sphere options enable high-sensitivity measurement of solid samples. Use the ASR Series of absolute specular reflectance accessories to perform high-accuracy absolute reflectance measurements. In addition, temperature-controlled cell holders and micro cell holders are available to handle a wide range of measurement applications.
A Wealth of Applications
Transmittance Measurement of Lenses
Imaging devices, such as mobile phones, digital cameras, and security cameras, are all equipped with lenses. The transmittance of a lens is one factor that determines lens performance. However, because the lens itself focuses light, it is an especially difficult type of sample to measure accurately.
Because of the focal capability of lenses, the total light passing through the spectrophotometer during the measurement of the baseline can be different than that after passing through the lens during measurement due to refraction. In such cases, the use of an integrating sphere can be used to collect all the light passing through the lens and provide for more accurate measurements. In addition, using the transmission-type integrating sphere included with the BIS-603 can reduce measurement errors.
Furthermore, using the V stage, provided as standard on the MPC-603 multi-purpose large-sample compartment, allows measuring the transmittance of lenses of various lengths and sizes. The MPC-603 and BIS-603 are an ideal combination for measuring lenses.
