The grating diffracts incoming light by the equation mλ = d(sin α + sin β), distributing it across 2048 detector pixels — each pixel resolving ~0.4 nm. This enables real-time absorption spectroscopy (Beer-Lambert law: A = εcl), fluorescence emission mapping, and transmission measurements. Applications include plasma emission analysis, UV-LED characterization, mineral identification, solar irradiance measurement, and teaching Beer's law directly.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWavelength range: 200–1000 nm; 2048-pixel CCD array, 0.5 nm optical resolution\u003c\/li\u003e\n\u003cli\u003e5 ms minimum integration time; SNR \u0026gt;1000:1 (at full well capacity)\u003c\/li\u003e\n\u003cli\u003eSMA-905 fiber optic input; USB 2.0 powered (no external supply needed)\u003c\/li\u003e\n\u003cli\u003eWindows\/Mac\/Linux SDK; Python library; real-time absorbance, transmission, and irradiance modes\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eEvery purchase directly funds independent physics research at the Golden Physics Project.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eExpert Analysis\u003c\/h3\u003e\u003cp\u003eA CCD-array spectrometer covering 200–1000nm represents the same fundamental measurement capability used in analytical chemistry, biochemistry, and environmental science laboratories worldwide. Unlike a scanning monochromator that sweeps one wavelength at a time, the array detector captures the full spectrum simultaneously — a complete absorption or emission spectrum in milliseconds. The 200nm UV coverage enables measurement of aromatic compound absorption, protein quantification at 280nm, and nucleic acid concentration at 260nm. The 1000nm near-infrared extension covers chlorophyll absorption, water bands, and NIR chromophores relevant to plant physiology and materials characterization.\u003c\/p\u003e\u003cp\u003eAt this price, sensitivity and stray-light performance are competitive with research-grade instruments that cost five to ten times as much a decade ago — a reflection of advances in array detector technology, not compromises in measurement capability. The SMA-905 fiber optic input accepts standard optical fibers for remote sampling in geometrically constrained situations. Connection to Python via the open-source python-seabreeze library makes this a genuinely programmable research instrument — build automated sampling sequences, integrate into a flow cell, or run continuous environmental monitoring.\u003c\/p\u003e\u003cp\u003eFew instruments at any price offer this range of experimental possibilities. Measure Beer-Lambert absorption coefficients quantitatively, characterize LED and laser emission spectra, analyze flame colors and plasma emission lines, or build a portable field spectrophotometer using this sensor and a Raspberry Pi. This instrument opens quantitative optical spectroscopy to small laboratories, science educators, and citizen scientists who previously had no realistic path to real analytical spectrophotometry.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54144350126372,"sku":"GPP-ELEC-UVVISSPECT","price":279.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/960px-DU640_spectrophotometer.jpg?v=1781220434","url":"https:\/\/shop.goldenphysics.org\/products\/usb-uv-vis-spectrometer-200-1000-nm-with-ccd-array-detector","provider":"Golden Physics Project","version":"1.0","type":"link"}
