Wide Field /Confocal Raman Microscope | SIMTRUM Photonics

Confocal Raman Microscope

MicroRam - Widefield Raman Microscope and Confocal Raman Microscope

Micro Raman is an easy-to-use tool for acquiring Raman Spectrum, with a motorized stage customers can perform Raman spectral image mapping of the samples. we have both Widefield and Confocal Raman model.

SIMTRUM’s Micro-Raman adopted a modular design concept, with an external connection port, providing great flexibility. Customers can always connect an external laser source or spectrometers to the systems.


Furthermore, our XY Microscope Piezo Stages has been designed for use our SIMSCOP Series Microscopes to provide motorized XY positioning of microscopy  samples. Access for SIMTRUM's XY Microscope Stages can be click here.

Upgraded System with Our High Sensitivity Spectrometer(HiNA)

HiNA vs QEP -  HiNA is 6.76x of QEPro on the Sensitivity Comparison

Sensitivity Comparison

10ms Un-normalized

Sensitivity Comparison

HiNA - 10ms, normalized with 65535 as maximum range

QE- 70ms, normalized with 200000 as the maximum range

Resolution Comparison

Test Conditions

1, A halogen lamp, blocks the light with a baffle so that the intensity is close to HiNA60000counts@10ms

2, Optical fiber: 600um

3, HiNA un-cooling, GODZ un-cooling, QEPro cooling

Calculation Process

1, QEpro reaches 18w counts at 70ms, reaching 90% of the saturation range (20W);

2, HiNA reaches 5.7W in 10ms, reaching 87% of the saturation range (63335);

3, Magnification calculations: 0.87/0.9 x 7=6.76
