FLEX

A Powerful and Flexible Spectrometer that Fits in the Palm of Your Hand

Perfect as a General Purpose Solution

Improved Optical Design – The Best in Class!

User-Interchangeable Slits and Optical Filters

Fiber Optic Spectrometer with UV-Vis-NIR (185-1100 nm) detection

AUTODARK through an included automatic SHUTTER

LightScan 2.0 Software Included

Robust, Compact, and Lightweight

The assembling precision of all optical components in a robust, compact, and lightweight bench provides the FLEX spectrometer with improved sensitivity, great peak symmetry, and low stray light through the operational wavelength range, making this series of spectrometers the perfect solution for most general spectroscopic applications.

 

Simple and Flexible

Features such as user-interchangeable slits and optical filters, shutter for Autodark, and triggering functions deliver simplicity and flexibility to your spectroscopic setup. FLEX is available in ready-to-use (for more common applications) and user-customized (for more specific applications) configurations for both STD (standard) and RES (improved-resolution) versions.

Key Features

  • A General Purpose Solution for Spectroscopic Applications

    With a compact and flexible design, FLEX is more than capable of delivering a great performance with improved performance and with the ability to be integrated into most general-purpose spectroscopic setups.

  • Best Optics for Minimal Stray Light

    FLEX is the perfect solution for those who have the need for absorbance/transmittance measurements. The simultaneous optimization of the optical and mechanical design provides FLEX with a very low stray light percentage (less than 0.1%, over the entire operational spectral range).

  • Integrated Shutter for AUTODARK

    The latest version of Flex spectrometers includes a fully automated shutter that eliminates the need to make the Dark step on your measurements. This way, every time you are performing the Reference step your spectrometer also records the Dark, making your life easier!

  • Easy to Integrate in Your Set Up

    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 by 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. Drivers for Labview TM and SDK for user application development are also available.

  • Bespoke Sensitivity and Resolution

    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.

  • Maximum Flexibility with the Best Performance

    FLEX is available in both standard (STD) and improved optical resolution (RES) versions for ready-to-use and user-customizable configurations. For both solutions, users have the possibility of choosing an improved sensitivity configuration, which translates into more efficient light collection optics.

  • Customize your Spectrometer

    Customizing optical components allows you to configure the FLEX for more specific applications. In addition to user-interchangeable slits and optical filters, the flexibility in selecting the diffraction grating, adding a collecting lens, or choosing the detector version helps you to set the operational wavelength range, sensitivity, and optical resolution of your spectrometer.
