Product Overview
The PS-100 Visible-NIR Spectrometer is a high-performance laboratory instrument designed for spectral analysis within 350-1000nm wavelength range. Featuring integrated packaging, it enables instant computer connectivity for immediate measurements, making it suitable for scientific research, agricultural studies, and environmental monitoring applications. Its rugged aluminum housing combined with precision optical components ensures reliable spectral data acquisition with high repeatability.117
Technical Features
Equipped with a 2048-pixel CCD detector and holographic grating (600 grooves/mm), the PS-100 achieves 1nm wavelength resolution with >1000:1 signal-to-noise ratio. The integrated APOGEE cosine corrector ensures accurate measurement of low-angle incident light, maintaining ±5% directional response accuracy within 300-1000nm calibrated range. With 16-bit digitization and adjustable exposure time (1ms-65s), it adapts to various light intensity conditions. Standard package includes 2m optical fiber, leveling base, and dedicated analysis software supporting USB plug-and-play operation.613
Applications
This spectrometer is typically employed for plant lighting spectrum analysis (measuring photon flux density/energy flux density), material reflectance/transmittance testing (e.g., plant leaf canopy analysis), and artificial light source characterization. The software system outputs radiometric data in W/m²/nm or mol/m²/s/nm units, supporting CIE 1931 chromaticity diagram analysis for color measurement and chemical composition analysis.15
Standard Configuration
Complete package includes spectrometer main unit, cosine-corrected irradiance head (with black cap), Apogee bubble level, 2GB USB drive (containing collection software and calibration files), blue USB cable, carrying case, and handheld extension rod. The instrument operates within 0-60℃ environment, with compact dimensions of 25×75×125mm and 500g weight, suitable for both laboratory and field applications.317
