Page 4: Safety
Any non-observance of the precautions will infringe the intended use (i.e. performing measurements by Raman spectroscopy) of miniRa- man spectrometer. In this case Lightnovo ApS will not assume any liability. It is the operator’s duty to plan and implement all necessary safety measures and to supervise their observance. -
Page 5: Warning Labels
Safety Warning labels This warning symbol indicates the existence of laser radia- tion. A Class 3R laser is considered safe if handled carefully, with restricted beam viewing. With a class 3R laser, the maxi- mum permissible exposure (MPE) can be exceeded, but with a low risk of injury. -
Page 6: Laser Safety
Laser Safety General Information The analysis system miniRaman microscope uses the light of a lasers (660 and 785nm) that are installed in miniRaman spectrometer. The used laser diodes emit visible and partially visible laser radiation in the near infrared region. -
Page 7: Installation
Warning: Do not put miniRaman spectrometer into operation if there are signs of damage. Fail- ure to do so may result in severe personal injuries and/or property damage. Transportation... - Page 8 Installation Space Requirements miniRaman spectrometer requires a space of 12cm in diameter and 4cm in height. (For the exact instrument dimensions refer to Specification.) At the rear instrument side, take a clearance of at least 3cm into account. Note: MiniRaman spectrometer is an instrument of protection class I (electric safety).

Page 10: Overview
SERS signals on plasmonic substrates, identification of pow- ders and liquids. MiniRaman spectrometer is also suitable for samples that tend to fluoresce when ex- posed to laser radiation. Due to the usage of a 785nm laser, the excitation energy is low enough for these samples not to fluoresces or only to a minor degree. - Page 11 Overview Lasers Depending on the selection of the miniRaman spectrometer model miniRaman spec- trometer could be configured in the following models with different laser parameters: • MiniRaman spectrometer Standard (includes one laser with optical isolation: 785 nm, power range on a sample 5-50 mW) •...
