1 Introduction
This manual gives you a comprehensive overview of the installation, func-
tioning and operation of the Mira M-1 instrument.
NOTE
You can request application descriptions in the form of
Application Notes and Application Bulletins from your
Metrohm representative or download them from
http://www.metrohm.com.
1.1 Instrument description
The Metrohm Instant Raman Analyzers (Mira) are handheld, high-power
Raman spectrometers designed for the rapid, nondestructive identification
of chemical and pharmaceutical samples, both liquid and solid. Barely
larger than a smartphone, the Mira spectrometers are the only handheld
Raman spectrometers currently on the market with Orbital Raster Scan
(ORS) technology.
1.1.1 Model versions
Mira M-1 instruments are available in the following versions:

The information below contain details of the NOHD calculation for the
Mira M-1 instrument in accordance with the international standard IEC
60825-1, "Safety of laser products".
WARNING
Laser radiation
The Mira M-1 Advanced instrument is a class 3B laser instrument
which emits laser light with a power of up to 100 mW and a wave-
length of 785 nm (NIR) during data acquisition.
The laser radiation can cause serious eye injuries if the safety measures
are not followed.
Uses, settings or procedures that are not described in this manual can
lead to hazardous laser radiation exposure.
￭This instrument is intended for use by trained personnel only.
￭The provided protective glasses must be worn when using an attach-
ment lens.
The provided protective glasses is designed specific for laser wave-
length and laser power of Mira M-1. The provided protective glasses
may possibly not protect you from other laser sources.
￭The nominal ocular hazard distance (NOHD) is 66 cm ± 5 cm.
￭Instruments of the laser class 3B may only be used in protected and
labeled rooms.
￭Follow the provisions of the IEC 60825-1 standard "Safety of laser
products" and the regulations for the use of laser systems in your
country.
1.4.3 Warning stickers on the instrument
The instrument is equipped with stickers that warn of potential hazards.
