Important Safety Notices
The laser described here is safe to operate, provided the user pays attention to all safety warnings:
1. Post warnings in the area of the laser beam to alert those present.
2. Keep all unauthorized personnel out of the area where the laser is operated.
3. Whenever the laser is running and the beam is not in use, it is good operating practice to
mechanically block the path.
4. Never look directly into the laser source or scattering laser light from any reflective surface.
Never sight down the beam into the source.
5. Maintain experimental setup at low heights to prevent inadvertent beam-eye contact.
6. As a precaution against accidental exposures to the output beam or its reflection, operators should
wear laser safety glasses attenuated to the wavelength being generated.

Laser Safety
WARNING
This device is intended for use by trained personnel only. Use of controls or
adjustments, or performance of procedures other than those described in this
manual may result in hazardous laser radiation exposure.
This is a class IIIB laser device and up to 100 mW of 785nm (NIR) laser light may be emitted during data
acquisition. Only personnel trained in laser safety protocols should be allowed to use this instrument.
The aperture warning label indicates where laser radiation may be emitted from the instrument when
using the point-and-shoot attachment. The laser safety goggles provided in the unit accessory kit must be
worn when using the point-and-shoot attachment.
Internal maintenance or repair must be performed at the factory or by authorized personnel only.

Locations of the Warning Labels
Remote Interlock
The IDRaman mini has remote interlock capability via the ID pin in the Micro USB port. Contact Ocean
Optics for more information on the remote interlock connector.
Nominal Optical Hazard Distance Calculations
The IDRaman mini is a Class IIIB laser device, containing a 785nm, 100mW rated laser diode. These
Class IIIB devices are hazardous when intra-beam ocular (eye) exposure occurs, i.e., when one
intentionally or unintentionally looks directly into the beam from within the Nominal Optical Hazard
Distance (NOHD). Never look directly into any laser beam. The information and calculations below
contain details of the intra-beam NOHD calculation for the IDRaman mini (785) in accordance with the
recognized international standard, IEC-60825-1, Safety of Laser Products, 2nd ed., 2007.
Assumptions
Safety interlock(s) failed or bypassed; Raster (motor) stalled or stopped; Laser on continuously at
maximum possible component power of 140mW, CW.

Chapter 1
Introduction
Overview
The IDRaman mini is the smallest, most powerful handheld Raman instrument available today. Designed
to make rapid and accurate measurements that identify, authenticate and verify samples, the IDRaman
mini is ideal for:
•Authentication analysis
•Counterfeit detection
•Rapid material identification
•Verification of incoming materials
•Harsh and demanding environments
•In-line or at-line testing
From rugged field measurements of chemical and explosive agents to quality assurance and quality
control in the laboratory, the IDRaman mini is a truly compact choice for fast and accurate measurements.
IDRaman uses an internal calibration routine to ensure the most accurate Raman shift data is acquired.
Measuring most samples in less than 9 seconds, the IDRaman provides visual confirmation of results and
displays both the sample and library spectrum with a confidence factor. You can store a library of
thousands of compounds in the IDRaman. Using a proprietary fluorescence rejection algorithm, the
IDRaman mini minimizes both false positive and false negative results. With IDRaman’s Raster Orbital
Scanning technology, the limitation of weak signals from unknown and non-uniform samples is
overcome.
Features
•Long battery life - >11 hours from 2 Lithium AA batteries
•Light weight – 330 grams (11 oz.)
•Compact size - 9.1 x 7.1 x 3.8 cm (3.6 x 2.80 x 1.5 in)
•Great flexibility – measures both liquids (vials) and solid samples (with accessory kit)
•Rugged design – made from solid aluminum

1: Introduction
2000-40000-010-02-201307
•High visibility display – 7.1 cm (2.8”) resistive touch display
•Easy to use – intuitive user interface via touch screen
•High speed acquisition – visual confirmation in <9.0 seconds
•Self-calibration – includes onboard software driven calibration
•Raster Orbital Scanning (ROS) function -- allows detection of inhomogeneous samples without
sample degradation
•Library recognition - use of proprietary data analysis algorithm for high accuracy identification
without low false positives and false negatives
Models
The IDRaman mini (IDR-MINI) is available as a standalone product or packaged with a helpful accessory
pack (IDR-MINI-KIT). The accessory pack can also be purchased separately (IDR-MINI-ACCY).
•IDR-MINI – Consists of the handheld
Raman spectrometer, a 785 nm excitation
source and a micro USB cable for
computer connection. A basic component
library is provided, as well as software for
you to build your own library. This version
provides for vial sampling only and
contains a box of 144 2 mL vials.
•IDR-MINI-ACCY – The accessory pack is
comprised of a point-and-shoot solid
sampling attachment, plus laser safety
glasses and a handy storage case.
•IDR-MINI-KIT – For your convenience,
the IDR-MINI and the IDR-MINI-ACCY
are available as a combined item for a
complete solution to your measurement
needs.

About Raster Orbital Scanning (ROS)
The Ocean Optics IDRaman mini uses ROS to rapidly scan a tightly focused beam in an orbital pattern,
allowing lower average power to produce high-integrity data from a larger area of the sample without
sample ignition or damage.
A tightly focused beam may result in noisy signals
or missing the Raman active target completely,
leading to false negative readings from unidentified
samples.
Increasing the spot size of the laser dilutes the
valuable information about the material, leading to
inconclusive matches or false identification of
samples.
ROS increases the effective size of a tightly
focused beam. Information is obtained with
complete integrity while sampling the large area
needed for complex mixtures or irregularly shaped
samples, leading to confident identification.
