We’ve combined into one package our high-sensitivity USB4000-FL Fluorescence Spectrometer with a broadband excitation source and all the accessories you’ll need for cuvette-based fluorescence measurements. Order a DISCOUNT-USB4000-FL before March 14, 2008, and you’ll receive a 20% discount on your system.

At the heart of the DISCOUNT-USB4000-FL is our versatile USB-interface spectrometer, configured with a grating covering the 360-1000 nm wavelength range, and a detector collection lens to increase light-collection efficiency and reduce stray light. The spectrometer also has a programmable microcontroller that lets you control the spectrometer and external excitation sources. You get all that, plus these great components.

 Here's what You Get

  • USB4000-FL Spectrofluorometer

  • Broadband Pulsed Xenon Excitation Source

  • Direct-attach Cuvette Holder & 10 mm Quartz Cuvette

  • Solarization-resistant 600 mm Optical Fiber

  • Linear Variable Filter with Adjustable Bandpass

  • Software for Windows, Mac & Linux

  • Rugged Carrying Case

Sold individually, this package costs over $5,500. Act before March 31, 2008 and your price is only $4,405.60!

Preconfigured with an L4 Detector Collection Lens to increase light-collection efficiency and reduce stray light, the high-sensitivity USB4000-FL covers the 360-1000 nm wavelength range. It also features a programmable microcontroller that lets you implement operating parameters in the software -- control the spectrometer and external excitation sources, and even retrieve data on external objects!

We have a limited number of USB2000-FL Fluorescence Spectrometers available for immediately delivery. The USB2000-FL is an earlier-generation version of the USB4000-FL that provides comparable sensitivity and performance for your fluorescence applications. Contact an Applications Scientist at 727.733.2447 or Info@OceanOptics.com for details.

Programmable Microcontroller

The USB4000-FL's onboard programmable microcontroller provides you with considerable flexibility in controlling the spectrometer and accessories. Through a 22-pin connector, you can implement all operating parameters in the software: control light sources, create processes, and retrieve information on external objects. You have access to 8 user-programmable digital Inputs/Outputs for interfacing to other equipment. (Contact an Applications Scientist regarding what you'll need to program the GPIOs.)

Optimal Performance

The USB4000-FL provides you with an affordable, high-performance 3648-element linear CCD-array detector with an optical bench that's small enough to fit into the palm of your hand. The USB4000-FL works the same way as other Ocean Optics spectrometers; it accepts light energy transmitted through single-strand optical fiber and disperses it via a fixed grating across the linear CCD array detector, which is responsive from 200-1100 nm.

Plug and Play Operation

The USB4000-FL interfaces to a PC, PLC or other embedded controllers via USB 2.0 or RS-232 serial port. Data unique to each spectrometer is programmed into a memory chip on the USB4000-FL; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.

Accessory Filters

The USB4000-FL can be used with our LVF-series Linear Variable Filters to construct systems with excellent separation of excitation and fluorescence energy. Use our LVF-L Linear Variable Low-pass Filter to fine tune your excitation source for maximum signal with minimum overlap; and/or use our LVF-H Linear Variable High-pass Filter on the detection side. Inline holders and cuvette fixtures make deployment of these filters easy.
