Origin
China

The USB4000-FL is our next-generation miniature spectrometer platform developed for fluorescence spectrometers! It provides enhanced electronic characteristics for fluorescence measurements, higher optical resolution, and a 10-microsecond integration time. When retrofitted with the L4 detection focusing lens, it increases absorbance and reduces stray light. The high-sensitivity USB4000-FL has a wavelength range of 360–1000 nm and an optical resolution of 10.0 nm (FWHM). The minimum integration time of the USB4000-FL can be set to 10 µs via software to handle short fluorescence periods. The USB4000-FL's programmable processor allows you to change operating parameters in software—control the spectrometer and external excitation sources, and even acquire data from external targets. The USB4000-FL, USB4000-FL-450, and USB-FL-395 are high-sensitivity preconfigured fluorescence spectrometers designed for fluorescence sensing applications. Each fluorescence unit is set in the 360-1000 nm wavelength range, with a 200 µm entrance slit and an L4 detector condenser for enhanced light collection efficiency. USB4000-FL: does not include an excitation source. The USB4000-FL does not contain an excitation light source, allowing flexible selection from a variety of small, low-cost, modular excitation sources, such as Ocean Optics' LED light sources. The excitation source generates pulsed or continuous signals, which are conveniently transmitted to the spectrometer, optical fibers, and sampling accessories. USB4000-FL-450 & USB4000-FL-395: come with an excitation source. The USB4000-FL-450 & USB4000-FL-395 spectrometers have the same configuration as the USB4000-FL, but they additionally include a light source. The USB4000-FL-450 uses a 470 nm LED light source, and the USB4000-FL-395 uses a 395 nm LED light source. When you are equipping the fluorescence spectrometer with a probe, we recommend that the USB4000-FL-450 can use FOXY and HIOXY probes, and the USB4000-FL-395 can use the FOSPOR probe. The spectrometer can power the LED, enabling synchronization and I2C communication functions. Moreover, the light source is also connected to a temperature sensor, with onboard memory that can store temperature and oxygen content calibration coefficients.

Key Features

Stronger light collection capability, less stray light 5 trigger options Response wavelength 360-1000 nm, optical resolution 10.0nm (FWHM) 10µs integration time Electronic shutter: 10µs to open the detector The integration time in our software is set by the user. Similar to a camera's shutter speed: the specified integration time is the time the detector observes incident photons. The USB4000-FL uses a 3648-pixel Toshiba TCD1304AP linear CCD detector. Because the Toshiba detector's electronic shutter can be set via software to an integration time as short as 10 microseconds, you can measure fluorescence events that occur instantaneously, like laser pulses. Programmable microcontroller The programmable microcontroller included with the USB4000-FL provides great flexibility for controlling the spectrometer and its components. Through a 22-pin connector, you can execute all operating parameters in software: control light sources, create processes, and acquire information from external devices. You have 8 user-programmable digital input/output ports to provide interfaces with other devices. Optimal performance The USB4000-FL uses Toshiba's high-performance 3648-pixel linear CCD array detector, and an optical bench small enough to fit in the palm of your hand. Its working principle is the same as other spectrometers produced by Ocean Optics; it accepts light transmitted through a single-core fiber, disperses it through a fixed grating, and delivers it to the linear CCD array detector, whose response wavelength range is 360-1000 nanometers. Plug and play The USB4000-FL connects to a PC, PLC, or other embedded controller via USB2.0 or RS-232 serial port. Each spectrometer's respective data is programmed in a memory on the USB4000. Our spectrometer control software reads these values for thermal transfer between PCs and fast parameter setup. Additional filters The USB4000-FL can be used with our LVF series linear variable filters to build a system that separates fluorescence and excitation light well. Use our LVF series linear variable low-pass filters to fine-tune your excitation source; and/or use our LVF series linear variable high-pass filters on the detection side to obtain the strongest signal with minimal overlap. The built-in holder and cuvette clamp make the filters easy to install.
