Devices for Spectrophotometer (UV to VIS).

PMT (photomultiplier tubes)

In the photosensor field, photomultiplier tubes (or PMT) are known to have particularly high sensitivity. PMT also have dozens of other advantages such as high-speed response time.

PMT modules

The PMT module is basically comprised of a photomultiplier tube to convert light into electrical signals, a high-voltage power supply circuit, and a voltage divider circuit to distribute the optimum voltage to each dynode, all assembled into a single compact case. In addition to these basic PMT modules, Hamamatsu also provides modules having various additional functions such as signal processing, cooling and interface to PC.

Xenon lamps / mercury-xenon lamps

Xenon lamps emit a continuous spectrum with high luminance and high color temperature, ranging from the UV to visible to infrared range.

Deuterium lamps

These are the next generation of deuterium lamps that deliver the high stability, high output and long service life required in deuterium lamps for spectrophotometry.

Xenon flash lamps

Xenon flash lamps are more compact than continuous mode lamps and build up less heat. They provide a high-intensity continuous spectrum from deep ultraviolet light to ultraviolet light to visible light to infrared light.

Xenon flash lamp modules

Xenon flash lamp modules are compact devices that integrate a xenon flash lamp (2W or 5W), power supply, and trigger socket. They provide high intensity, high repetition flashes across a broad spectrum from ultraviolet to infrared.

UV-VIS fiber light sources

This is UV-Visible fiber light source for complete range of portable systems. There are two types, L10671 and L10290. The L10671 contains S2D2 (Stable & Small Deuterium) lamp and tungsten lamp which emits range of 200nm to 1600nm. The L10290 contains high brightness deuterium lamp and tungsten halogen lamp which emits range of 200nm to 1600nm.

Compact D2 lamp modules

The S2D2 compact deuterium lamp is a UV point light source with a drastically reduced size compared to ordinary deuterium lamps. 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.

Si photodiodes

CCD image sensors suitable for high-precision spectrophotometry.
Back-thinned type CCD are designed to deliver high quantum efficiency (90% or more at peak sensitivity wavelength).

Mini-spectrometers

HAMAMATSU mini-spectrometers are polychromators integrated with optical elements, an image sensor and a circuit. Light to be measured is guided into the entrance port of ï½”hrough an optical fiber and the spectrum measured with the built-in image sensor is output from the USB port to a PC for data acquisition.
