Diffuse reflection light source L16462-01

L16462-01 is a module with built-in lamps and an optical fiber for doing diffuse reflection measurement in near-infrared spectrophotometry. This module irradiates a sample with light from lamp, allowing the light to enter the sample.
This light is then diffused and reflected, and guided to an optical fiber.
The L16462-01 is connected to a near-infrared spectrometer etc. to perform spectroscopic analysis. With this product, in which plural lamps and an optical fiber are arranged close to each other, the weak diffused light emitted from the sample can be detected efficiently.



- Compact: Φ28.0 mm × 35.5 mm

- Long life: 7000 hr (average)

- High detection efficiency (built-in multipul lamps)

- Wide wavelength range: 400 to 2500 nm

5W xenon flash lamp module

Hamamatsu offers xenon flash lamp modules containing a 5 W xenon flash lamp along with its power supply and trigger socket. Up to 5 W of energy can be input, which is the maximum among lamp modules of this size. These xenon flash lamp modules also deliver high stability and long service life, making them ideal as a light source for water quality and atmospheric analyzers.
Different types of lamp modules are provided: side-on type, head-on type, and twice higher light output type than the other lamp modules currently in use.
Also offered are the SMA fiber adapter type, silent type, and high precision type.


L9455series (High stability type)

L11316series (High output type)

- High stability : 1.5 % CV or less

- Long life : 1 × 109 flashes or more

- Repetitive emission frequency : 530 Hz Max.

2W xenon flash lamp module

The L13651 series is a 2 W xenon flash lamp module that has achieved miniaturization by integrating the illumination operating circuit. This product is not only an ideal light source for compact analysis equipment used in environmental analysis, sampling tests, and the like but also can be incorporated in portable analysis equipment used in high accuracy environment monitoring, POCT, and the like with operation on a 5 V mobile battery, whose development is expected in the future.



- Compact size: 42 × 42 × 37 mm

- Long life: 1 × 109 flashes

- Repetition rate: 1250 Hz Max.

- Broad spectrum: UV to middle IR
