Generally, the irradiation light source configured with a xenon lamp and band pass filter is cheaper while it is not convenient since the irradiation wavelength cannot be selected without any restriction and different filters have to be prepared to use different wavelengths.

The NIJI-3 has been developed to irradiate approx. 2 times higher light intensity ( in the wavelength range from 300 to 400nm ) than that of the conventional model, NIJI-2 by optimizing the light source part for high intensity in the UV region and employing high efficiency grating. Selecting the UV range wavelength, the NIJI-2 is ideal for the deterioration test , excitation light source for fluorescence measurement, the UV light reaction and etc..

Major application

Photocatalysis / Photochemical reaction

As a strong light source for photocatalyst and photochromic

compound, any wavelength in the range of 300~1150nm can

be selected and its monochromatic light can be irradiated.

Evaluation of spectral characteristic of the solar cells

Evaluation of spectral characteristic the CCD and photo sensors

As a light source for a photoelectric conversion

device, any wavelength in the range of 300~1150nm

can be selected and its monochromatic light can be irradiated.

Photo simulation / Photosynthetic reaction

Cell activation by light illumination can be analyzed and also

effective wavelength for photosynthetic reaction can be

selected and irradiated.

Light source for illumination / Light source for a microscope

As a light source for monochromatic illumination and

fluorescence excitation light source for a microscope, the

Model NIJI as a light source is very effective.

Achieve High UV light irradiation with more than 1mW

High intensity monochromatic light (300~400nm) can be irradiated. Using a bundle optical fiber for the irradiation head as a outlet of the system, irradiation area (size) can be adjusted to meet various applications.

 

Turning the dial, irradiation wavelength can be selected

By turning the dial, you can choose the wavelength with 0.1nm step for irradiation.

Wavelength indicator makes the operation easy and comfortable

When selecting the wavelength at 600nm for an example, the wavelength indicator lights if there is any problem on the system.

Turning the dial, irradiation wavelength can be selected

Conventional system consists of a xenon lamp, optical system and monochoromator separately. The NIJI-2 is an integrated system which require minimum installation space. The system is stand-alone so that no PC is required. Compact and light weight design allow the customer to transport the system easily with a handle.
