Expandable UV-2600i for reflectance measurements to near-infrared
Bright optics support measuring a wide variety of samples, from liquids to solids.
Optional ISR-2600Plus integrating sphere enables even near-infrared measurements from 220 to 1400 nm.
High-accuracy UV-2700i captures even 0.000001 % (8 Abs) levels.
UV-2700i double-monochromator design with ultra-low stray light diffraction grating enables measurements to high 8 Abs absorbance levels.
Measures samples ranging from highly concentrated samples to thin films, even capturing extremely slight light levels from samples with low transmittance characteristics.
Highest sensitivity in class with three detectors
In addition to PMT and PbS detectors, also includes an InGaAs detector for the near-infrared region to achieve high sensitivity in all wavelength regions. Large sample compartment and integrating sphere unit with three-detector capability enable high-sensitivity measurements of even solid samples.
High resolution, ultra-low stray light, and wide measurement wavelength range
Achieves high resolution (max. 0.1 nm) and ultra-low stray light (max. 0.00005 % at 340 nm)

High sensitivity and wide measurement wavelength range
Achieves high-sensitivity measurements in deep UV region below 190 nm or in near-infrared region.
Enables measurements over a wide range, as wide as 165 to 3300 nm (using optional product).
Large sample compartment accommodates a wide variety of samples
Large samples up to 700 × 560 mm can be placed horizontally for each measurement.
An absolute reflection measuring device and a variable angle measuring device are installed in the sample chamber for various measurements.
In solid state measurement, a unique confocal optical system allows the selection of collimated and focused light.
