Diffuse reflection light source L16462-01

An ever-increasing market demand in near-infrared spectroscopy has led Hamamatsu Photonics to design and develop a diffuse reflection light source (L16462-01). The new light source irradiates near-infrared light at wavelengths up to 2,500 nm onto samples and collects the diffuse reflection light (*1) with high efficiency.

This diffuse reflection light source increases the light utilization efficiency in wavelengths ranging from 1,700 nm to 2,500 nm, where light intensity was up to now usually too weak for performing real-time component analysis using near-infrared spectroscopy. Combining this with our high-sensitivity FTIR (*2) spectrometer engine allows for a compact portable FTIR analyzer that is easily installable on production lines for food, pharmaceutical and plastic products. This not only automates the quality control process, but also improves production efficiency and quality control reliability. The L16462-01 also delivers higher accuracy in analyzing samples that contain fats and proteins, etc. Moreover, using it in applications to screen and sort plastics will promote plastic recycling.

Sales of this diffuse reflection light source will start on Wednesday, February 1, 2023 for domestic and overseas manufacturers of food, pharmaceutical and plastic product manufacturing equipment. We will also have this light source on exhibit at the “SPIE Photonics West 2023”, which is an international conference on photonics and related technologies held in San Francisco, California, USA from Tuesday, January 31 to Thursday, February 2, 2023.


*1: Diffuse reflection light is light emitted from the surface of a sample after being repeatedly diffused through refraction and transmission inside the sample when irradiated with light. Diffuse reflection light is used to analyze opaque samples with irregular surfaces such as food and powder products.

*2: FTIR stands for Fourier transform infrared and is one of the most popular types of infrared spectroscopy. FTIR spectroscopy can analyze and identify the type and quantity of chemical components contained in a sample by irradiating infrared light onto it and then measuring the intensity of the transmitted or reflected light at each wavelength.
