Experience highest grating flexibility

Selecting the optimal diffraction grating is essential for achieving meaningful spectroscopic results. The choice depends on the spectral region of interest and required resolution. With 6 positions, Hexalight offers the flexibility to select the optimal grating for each of your applications in one system. This is especially valuable for advanced approaches that require a wide range of capabilities, such as obtaining varied spectral information from a single sample, working with different laser wavelengths, or performing correlative measurements such as Raman and photoluminescence (PL).

Monolight: Applications with a fixed spectral configuration

For applications requiring only one spectral configuration, Monolight is the budget-conscious alternative to Hexalight. It features a single fixed grating while retaining key advantages of Hexalight’s optical design and throughput. 

Monolight is the standard spectrometer for the alphaCART portable Raman system.

Fibre-based Beam Delivery: Facts and Benefits

Our advanced photonic fibre technology ensures that the Hexalight and Monolight spectrometers operate with the highest light transmission efficiency.

Benefits of Fibre-Based Beam Delivery:

• Virtually Lossless Transmission: Ensures maximum signal throughput for sensitive Raman signal detection.
• Enhanced Spatial Resolution: Fibre-generated diffraction-limited point light source ensures true confocality.
• User-Friendly Operation: Pre-aligned fibre-coupling units simplify setup and provide long-term stability.
• Reduced Interference: Remote laser placement minimizes thermal and vibrational disruptions near the microscope
