产品介绍

OPRex-MMS 宏观采样显微光谱仪是一款模块化光纤耦合显微光谱平台，专为原位催化表征和材料分析设计。采用约100 μm的宏观采样光斑，在保持空间分辨能力的同时确保对非均质样品（如粉末催化剂床层）的代表性采样，有效避免传统共聚焦显微镜因采样点过小导致的局部偏差。平台采用模块化光谱盒子设计，每个模块集成独立的光源、光栅与探测器，可根据需求同时安装多个模块，实现拉曼、漫反射等多种光谱的同步或切换测量。可与谱迅全系列原位反应池联用，在高温高压真实反应条件下进行原位光谱测量。

Macro-Sampling Micro-Spectrometer

OPRex-MMS

PRODUCT INTRO

The OPRex-MMS is a modular fiber-coupled micro-spectroscopy platform designed for in-situ catalysis characterization and materials analysis. A ~100 μm macro sampling spot preserves spatial resolution while ensuring representative sampling of heterogeneous samples such as powder catalyst beds, avoiding the local bias inherent to conventional confocal microscopes. Each modular spectroscopy box integrates its own light source, grating and detector, and multiple modules can be installed simultaneously to enable synchronous or switchable Raman and diffuse reflectance measurements. The platform couples with the full Puxun range of in-situ cells for spectroscopic studies under realistic high-temperature, high-pressure reaction conditions.

PRODUCT ADVANTAGES

Modular design: each spectroscopy module is a self-contained box, freely combinable, and multiple modules can share the same microscope platform
Macro sampling: the 100 μm spot balances spatial resolution with sample representativeness, particularly suited to heterogeneous powder catalysts
High-performance spectrograph: 120 mm Czerny-Turner optical path with a back-illuminated CCD (200-1100 nm response)
In-situ coupling: seamless integration with the full Puxun range of in-situ reaction cells
Anti-reflection (diffuse module): static off-axis deflection eliminates specular reflection and delivers clean diffuse-reflectance spectra

NOTE

Product codes follow the installed module combination; e.g. OPRex-MMS-R532-DV denotes a unit configured with both the 532 nm Raman module and the visible diffuse reflectance module. The DV module uses Puxun's proprietary light source (Chinese patent CN202610287518.0), and the DUV module integrates deuterium and LED sources losslessly via a dichroic mirror. Changes to grating or slit will affect spectral resolution and coverage — please consult technical staff when selecting options.
