Spot light sources(2)

RF electric discharge type excimer lamp(3)

With conventional dielectric barrier discharge, a needle-shaped microplasma discharge occurs at 10 kHz operation, which results in uneven illumination. By contrast, high-frequency RF discharge produces a cloudlike glow discharge at 2 MHz operation, which results in highly uniform illumination. This feature enables the excimer lamp to provide stable output with minimal flickering.

Opto-Spectrum Generator (OSG)(1)

With just one OSG you can freely select any desired wavelength in 1 nm steps with wavelength tuning at 50 nm per second. Product lineup gives a light emission spectrum ranging from 340 to 540 nm, 390 to 700 nm and 430 to 790 nm as a standard product feature. Emits light at any desired wavelength with high reproducibility by delivering a spectral bandwidth of approximately 20 nm. This featuremakes the OSG the ideal light source for evaluations and tests that demand higher accuracy than ever.

Flash light sources(2)

Selecting the desired optical system components such as the lightguide allows the flash light source to emit a variety of different types of light.

Despite a compact body, the S2D2 lamp has the same high stability as conventional deuterium lamps and a unique electrode structure that delivers high luminance. This compact size of the S2D2 module makes it easy to install in all types of equipment. The dedicated lamp housing and power supply are designed to extract maximum performance from the S2D2 lamp.

Xenon flash lamp modules(9)

Despite its high brightness, the H2D2 is highly stable, has a long service life, and allows air-cooled operation by a specially designed housing.

Electrostatic removers(5)

The Photoionizer is a completely new type of electrostatic remover using "photoionization" for clean, easy, yet effective generation of ions. The Photoionizer provides big advantages over the corona discharge method which is generally used.

VUV ionizer(1)

The L12542 is a newly developed electrostatic charge remover that makes use of VUV (vacuum ultraviolet) light. Due to its wide irradiation angle about 3 times larger than our current VUV light source, the L12542 efficiently removes electrostatic charges over large areas in depressurized or vacuum environments. Up until now two or more VUV light sources were needed to neutralize electrostatic charges in large areas due to their limited irradiation angle. The L12542 solves this problem and efficiently neutralizes large areas in a vacuum.

Terahertz photoconductive switch(2)

Terahertz wave generator / detector

The spectral region between light and electrical wave is known as terahertz(THz) region from the viewpoint of its frequency. This far-infrared spectral region has recentry attracted considerable attention for its potential application in spectrscopy, imaging, telecommunications, medical analysis, and so on. Terahertz photoconductive switch can generate/detect terahertz electromagnetic wave with femtosecond pulse laser as an excitation light source. When constructing terahertz time domain spectroscopy, two modules are required for emission and detection.
