High Performance Spectrometers for Fluorescence Applications

High Performance Spectrometer

For fast, sensitive fluorescence spectroscopy

By combining their "Ultimate Diffraction Grating" with efficient f/1.3 or f/2.0 optics, Warsatch Photonics has created the World’s Fastest Spectrometers. In addition to speed, the innovative optical design provides for a high-performance spectrometer in a small package. When tested side by side, Warsatch's spectrometers consistently outperform larger, more expensive units. The VIS and VIS-NIR spectrometers are ideally suited for demanding fluorescence applications, with the high throughput allowing for low light level detection and fast integration times. This spectrometers can detect fluorescence in the attomolar region.

WP VIS Spectrometer Features/Benefits:

  • Wavelength range: 400-800nm with 2nm resolution (VIS model)
  • Wavelength range: 420-1100nm with 4nm resolution (VIS-NIR model)
  • HD Volume Phase Holographic Grating
  • Back-thinned Si CCD with low noise electronics
  • Extremely low stray light and high transmission
  • Short acquisition time and high SNR spectra
  • TEC cooling option available
  • Bluetooth option available
  • Fibre coupled or free-space
  • OEM solutions offered

The Wasatch fluorescence spectrometer range:

Spectrometer Range What You Need to Know
WP VIS 400-800nm F/#: 1.3, 2nm resolution
 WP VIS-NIR  420-1100nm  F/#: 2.0, 4nm resolution

The back-thinned CCD detector is optionally available with a TEC (thermo-electric cooler) for enhanced sensitivity. Bluetooth communication is also available as an option, while you can choose from a fibre-couple or free-space input.

Wasatch supplies Dash Software, a platform developed specifically for data acquisition. Dash is able to continuously log data or take spectra individually to export for quantitative analysis. It is designed specifically to interface to existing software platforms or a custom software platform. Also included are software development kits (SDK’s) to enable development of software for specific platforms.

Dash software has been tested on Windows 7, Vista, XP and to a limited extent, XP embedded. While Windows 7, Vista and XP Service Pack 2 provide all of the required libraries for Dash functionality, certain XP embedded installations will require the installation of MS Visual Studio 2008 runtimes and other libraries. Please consult your embedded system build documentation for details on how to install these libraries. The best user experience comes with a Windows 7 64-bit system with an Intel i7 processor and at least 2GB of RAM.
