What are the key performance specifications of the Atomfair-LRS-837 Raman spectrometer, specifically resolution and stray light levels?
The LRS-837 achieves a spectral resolution of ≤0.1 nm at 500 nm and stray light ≤10⁻³, with a scanning range from 0 to 1200 nm. These performance metrics are supported by a monochromator featuring a relative aperture D/F=1/5.5, a 1200 L/mm grating, and a slit width continuously adjustable from 0 to 2 mm with 0.01 mm precision.
What sample types and optical components can be used with the LRS-837 Raman spectrometer?
The instrument supports liquid and solid samples via multiple dedicated stages: a 5‑dimensional adjustable vertical sample stage, horizontal liquid sample stage, transparent solid sample stage, oblique incidence solid sample stage, and a backscattering sample stage. The external optical path system is compatible with polarizers, analyzers, waveplates, and Raman filters for advanced experimental configurations.
What are the physical dimensions, weight, and laser safety considerations for installing the LRS-837?
The unit measures 700 mm × 500 mm × 450 mm and weighs 70 kg. It uses a 532 nm semiconductor laser with output power ≥100 mW, requiring standard Class 3B laser safety practices (laser‑safe eyewear, enclosure, and warning signs). The instrument should be placed on a stable optical table within a controlled laboratory environment to minimize vibration and ambient light interference.
The Atomfair-LRS-837 Educational Laser Raman Spectrometer is a compact, fully computer-controlled instrument designed for academic Raman and fluorescence spectroscopy, featuring a 532 nm semiconductor laser, a high-resolution monochromator (≤0.1 nm at 500 nm), and a single-photon counting system for sensitive detection. Its 5-dimensional sample stage and external optical path compatibility with polarizers and waveplates make it versatile for liquid and solid samples, though its 70 kg weight and 0–1200 nm scanning range require dedicated lab space and careful optical alignment.
Positive
- High-sensitivity single-photon detection: The photon-counting photomultiplier tube with a signal discrimination circuit provides low-noise detection, enabling measurement of weak Raman and fluorescence signals typical of academic samples.
- Versatile sample stage configurations: The 5-dimensional adjustable vertical stage, horizontal liquid stage, and backscattering stage support diverse liquid and solid sample geometries, enhancing experimental flexibility in teaching and research.
Trade-offs
- Heavy benchtop footprint: At 70 kg and 700×500×450 mm, the instrument requires a reinforced, dedicated lab bench and sufficient clearance for operation and maintenance, which may limit portability or placement in crowded teaching labs.
- Manual slit adjustment required: The continuously adjustable slit (0–2 mm, 0.01 mm precision) demands manual calibration and operator expertise to maintain resolution and repeatability, adding complexity for novice users.
