The Electron Tube Division strives to support progress in most advanced photonics technologies involving low-light-level and ultra-high speed measurements.

These photosensors have both high sensitivity and high-speed response and offer optimal performance even for special applications.

These photosensor products are developed for particular applications while retaining the outstanding features of photosensors.

Light captured in two dimensions can be conveyed to us as visual information through images.

These are image sensor products with enhanced features such as shutter functions that boost the inherent value of high-performance image sensors.

Utilizing the high-precision glass processing technology essential for manufacturing electron tube devices, we have developed optical elements.

The light output stability and service life of a lamp greatly affect the measurement precision, equipment maintenance and running costs.

Our light source products incorporate high-performance lamps developed based on our long years of research on "light", and are capable of efficiently extracting the required light.

Non-destructive inspection using X-rays is being applied in many areas in industrial fields where demands for higher quality are always on the increase.

The Photoionizer is a completely new type of electrostatic remover using "photoionization" for clean, easy, yet effective generation of ions.

In Stealth Dicing, a laser beam at a wavelength capable of transmitting through the material is condensed on an internal point in that material.
