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 Model NIJI 2 Variable Wavelength Light Source is capable to perform irradiation at any wavelength in the range of 300~1150nm using the monochromator instead of the band pass filter. In the past, the light source with the monochromator had a disadvantage over that with band pass filter since it reduce intensity of the light. Development of our new optical system in the monochromator for the model NIJI 2 has overcome such technical problem and has been successful in generated monochromatic light with high output of intensity such as more than 1mW ( at 480nm).

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.

High output monochromatic light irradiation with more than 1mW

When wavelength purity was selected at 20nm with Φ3mm bundle fiber and total luminous flux entered.

Monochromatic light in the range of ultraviolet , visible , and Infrared (300~1150nm) can be

irradiated with high output intensity. Using a bundle fiber on the outlet of the system,

irradiation area can be adjusted for 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.
