Description:

The USB2000+ squeezes a crossed Czerny–Turner bench, Sony ILX511-B 2048-element CCD array and 16-bit A/D into a housing barely larger than a deck of cards. Plug a 5 µm-core fiber into the SMA 905 connector, attach the USB 2.0 lead and OceanView software auto-identifies the bench version—UV-VIS (200–850 nm) or extended VIS-NIR (350–1100 nm)—loading pre-calibrated wavelength tables stored in onboard EEPROM. Optical resolution down to 0.35 nm FWHM is possible with a 10 µm slit, and user-swappable order-sorting filters tame second-order stray light below 0.05 %. Integration times from 3 µs to 65 s cover laser pulse work through faint Raman scattering, while a 12 000:1 saturated signal-to-noise ratio ensures quantitative absorbance to 3 A. A 20-pin header exposes SPI for OEMs, and the master draws only 250 mA from the host, needing no wall supply. Aluminum extrusion with dovetail feet weighs 6.7 oz and measures 3.5 × 2.5 × 1.4 in, mounting almost anywhere a fiber can reach.

Economic Advantage:

By eliminating cooling, HV supplies and bulky gratings yet keeping sub-nanometer resolution, the USB2000+ democratized spectroscopy: hundreds of units cost less than one research-grade bench, letting startups embed spectral QA directly on production lines and universities outfit every student station.
