FLEX+

A General Purpose Spectrometer with a Plus in Sensitivity and Speed

Ideal for Low Light-Level Applications

Equipped with High-Sensitivity CCD Detector

User-Interchangeable Slits and Optical Filters

UV-Vis-NIR (185-1100 nm)

Fast Acquisition – Up to 2587 Spectra per Second

LightScan 2.0 Software Included

Flexible and Fast

In addition to the great performance and flexibility of the FLEX series, the FLEX+ series is a more sensible solution for low-light-level applications that require high performance and a wide dynamic range such as low emissive fluorescence measurements. The Hamamatsu back-thinned CCD detector has 1-mm height pixel elements, which provides higher sensitivity and delivers high quantum efficiency (around 80% at the maximum) with a great signal-to-noise ratio.

 

Simple and Flexible

This spectrometer combines high sensitivity, fast acquisition (up to 2587 spectra per second), and features such as power status indicators, user-interchangeable slits and optical filters, or plug-and-play operation. This way, the FLEX+ delivers simplicity and versatility to all the setups that include this system. FLEX+ spectrometer is available in a ready-to-use (for more common applications) and user-customized (for more specific applications) configuration for narrow UV-Vis and Visible-NIR range and extended UV-Vis-NIR range.

 

Key Features

  • Control the Sensitivity and Optical Resolution of Your Spectrometer

    With the FLEX+ you can take advantage of interchangeable slits and optical filters. User-interchangeable slits offer an easy and simple way of setting the ideal optical resolution/sensitivity while interchangeable optical filters provide the user with the ability to narrow the operational wavelength range of the spectrometer. These features allow you to change from absorbance to a fluorescence setup in a few minutes. Add a Slit Kit to your order and get all the flexibility you need.

  • The Ideal Solution for Low Light-Level Applications

    The Hamamatsu back-illuminated CCD detector used on FLEX+ has great performance advantages such as low dark counts. The 1 mm height pixel elements on the detector provide higher sensitivity for low-light-level applications.

  • Fast Acquisition for Monitoring Real-Time Events

    FLEX+ allows you to work with an integration time as low as 2 microseconds (with the electronic shutter on) and acquire up to 2587 spectra per second (using the burst mode). This feature makes FLEX+ the ideal solution for chemical, biochemical and other applications where fast reactions need to be monitored.

  • General Purpose Solution with a Plus

    The FLEX+ is the full package of the FLEX series but with extra sensitivity and speed, which makes this spectrometer ideal for users that require fast and more sensitive light detection.

  • Easy to Integrate in Your Setup

    The SMA fiber optic connector allows for a simple attachment of FLEX+ to a wide range of spectroscopic setups without the need for complex optical alignments. This flexibility is complemented with a trigger integration tool, which includes triggers in/out and delays. FLEX+ and all spectroscopic components of your setup can be centralized for full control with our new SPEC Hub solution.
