Luminescence Analyser

Luminescence Analyser

This analyser is based on a proprietary technology for demanding measurement tasks in both scientific research and industrial applications.
Technology From: Enhanced Spectrometry Inc.

Luminescence Analyser

The EnSpectr L405® sets new records at blue-violet wavelengths. It is unique luminescent analyser that unites highest resolution and superior sensitivity in a compact design. It is based on a proprietary technology for demanding measurement tasks in both scientific research and industrial applications.

EnSpectr L405 utilises a 30µm entrance slit, 1200g/mm grating and cutting-edge low pass filter. The luminescence is excited by a 100mW semiconductor laser at 405 nm to provide a single shot luminescence spectrum in the spectral range from 450nm to 770nm.

It comes with a low-noise 3648-element linear-array CCD

Charge Coupled Device
detector operating at room temperature and a state of the art system for suppressing the Rayleigh scattering signal and the straight laser light.

Raman and Luminescence Analyser

Raman and Luminescence Analyser

The EnSpectr R532® is a unique instrument that combines the advantage of a portable probe system with the performance of a highly specified laboratory instrument.
Technology From: Enhanced Spectrometry Inc.

Raman and Luminescence Analyser

The EnSpectr R532® is a unique instrument that combines the advantage of a portable probe system with the performance of a highly specified laboratory instrument. It is the perfect choice for Raman analyses where high quality data is essential.

Real-time and accurate identification of an unknown substance occurs by comparing its unique Raman spectrum of molecular vibrations (molecular "fingerprint") to Raman spectra of reference substances stored in a spectral database. EnSpectr R532 identifies through walls of sealed bags, transparent bottles, vials, and ampoules. The ease of use, single-hand operation, small size and weight of EnSpectr R532 allows testing chemical substances at the point of receipt, use, or delivery. Results are displayed within seconds and can be accessed via an intuitive user interface. Data are retrieved remotely via USB port.

Key Features
  • Superior sensitivity and low noise
  • Non-contact real-time identification
  • Analysis of ultra-low concentrations based on SERS
    Surface Enhanced Raman Spectroscopy
    proprietary technology
  • Precisely tailored to customers' requirements
  • Fast and trustworthy results
  • Portable device
  • Easy to use
Low Wavenumber Raman Now Available
  • Spectral resolution: 3cm-1
  • Raman Shift (anti-Stokes): (-1000)cm-1 to (-7)cm-1
  • Raman Shift (Stokes): 7cm-1 to 4000cm-1
