special Warnings about lasers
CAUTION – USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE
• This product includes lasers, or is designed to be upgraded with lasers, so you must be aware of the hazards
associated with the use of the powerful laser radiation that can be emitted by this product
• Laser radiation differs from ordinary light primarily because its optical power can be concentrated into a
narrow, low-divergence beam, whereas, for example, a standard light bulb diffuses its light in all directions and
thus spreads out its power. It’s a bit like the difference between walking outside on a sunny day versus having
the sun’s light concentrated on your skin using a magnifying glass
• Skin damage or deeper injury can be caused by lasers, but the eye is especially susceptible as laser light can
be collimated into a narrow beam that can enter the eye and permanently damage the retina with life-changing
consequences.
• Be aware that visible laser light is dangerous as well as invisible, that this laser product is not fully safe as you
usually have access to hazardous laser radiation. Laser safety for this type of product is about reducing risk,
rather than being able to eliminate it because access is required for the performance of this product
• Andor strongly recommend that all facilities have an established system for the safe use of lasers as per their
national regulations and occupational health and safety legislation. IEC TR 60285-14 Safety of laser products
– Part 14: A user’s guide and the American National Standard for the Safe Use of Lasers (ANSI Z136.1) are
standard references for good practice
use of tHe optional cc52 collector/colliMator WitH alignMent laser
The intended use of this laser product is only when the Laser Module is connected into the CC52 Collector/Collimator
(see Section 2.4). The Laser Module should only be powered when fully assembled in this conguration to reduce the
exposure to laser radiation. The Laser Module by itself and the Laser Module when connected just to the bre should
not be powered as the laser output in these two scenarios is unnecessary and is greater than that emitted by the CC52
Collector/Collimator.
If cleaning, assembling or disassembling this equipment, ensure that the power is disconnected.

guidelines for tHe safe operation of laser products
Please note that not all of the following guidance may apply to your product, e.g. you may not have invisible
lasers.
1. Never look into a laser beam either directly or indirectly.
2. Read the safety instructions supplied with all equipment in the system.
3. Ensure that the laser equipment is used in accordance with national guidelines.
4. Ensure all personnel requiring access to the product are fully trained in both using the product and the general
use of lasers.
5. Ensure users are familiar with the hazardous properties of lasers, especially that laser safety hazards differ
from those of normal light/radiation sources as they are highly-concentrated, very low divergence beams of
radiation.
6. Ensure end-users are familiar with the operation of the laser’s key switch control, interlocks, emission LEDs
and other safety features.
7. Restrict and control access to the area(s) where laser(s) are in use to those persons who are trained in the
dangers of lasers and trained on the safety precautions to be observed when working with lasers.
8. Ensure that all interlocks are connected and functioning correctly, where applicable.
9. Ensure suitable laser warning signs are prominently displayed in the area the system operates.
10. If the system is not in use, turn the laser off using the key switch, where applicable.
11. Do not attempt to disassemble the unit housing the lasers or any part of the system. If there is a problem
please contact Andor directly (see Section 1.1, ‘Technical Support’).
12. On a daily basis, or before every use, verify that the laser interlock circuit (if applicable) is working by
conrming that the laser emission indicator on the source(s) turns off when any of the following are done:
• The microscope ocular eyepieces are activated/engaged for viewing.
• The articulated transmitted light arm on inverted microscopes is tilted back from the functional vertical
position before using the system.
• Each beam splitter is removed from the unit.
• Any other interlocks on your system.
13. Fluorescent cards should be used to visually locate and indicate the output of invisible wavelengths at all
times, where applicable.
14. Additional precautions may need to be implemented as the necessary precautions will be specic to each
system installation, conguration and typical mode of use. The responsible Laser Safety Ofcer must assess
and implement the necessary precautions to avoid possible exposure to hazardous radiation during use.
15. We recommend that a copy of the latest edition of IEC 60285-1 Safety of laser products – Part 1: Equipment
classication and requirements is purchased by the Laser Safety Ofcer for reference, as well as IEC 60825-14
Safety of laser products – Part 14: A user’s guide.

Safe Safe Safe
Laser products that emit visible radiation
that are safe for momentary exposures but
can be hazardous for deliberate staring into
the beam.
The time base of 0,25 s is inherent in the
denition of the class and presumption
is that there is very low risk of injury for
momentary exposures that are somewhat
longer.
3R‡
Direct

Not considered
intrinsically safe Safe Safe Safe
Not considered intrinsically safe, the risk is
limited because
– unintentional exposures would rarely
reect worst-case conditions of (e.g.)
beamalignment with a large pupil and
worst-case accommodation with the entire
beam energyentering the eye,
– of the inherent reduction factor (safety
margin) in the MPE,
– of natural aversion behaviour for exposure
to bright light for the case of visible
radiationand by the response to heating of
the cornea for far infrared radiation.The risk
of injury increases with exposure duration,
and exposure may be hazardous for ocular
exposure under worst-case conditions or
for intentional direct intrabeam viewing.

optical instruments”.
The following terms are dened as follows:
• Intrabeam ocular exposure: Getting your eye in the way of a laser beam.
• Nominal Ocular Hazard Distance (NOHD): Distance from the output aperture beyond which the beam irradiance
or radiant exposure remains below the appropriate corneal maximum permissible exposure (MPE).
• Accessible Emission Limit (AEL): Maximum accessible emission permitted within a particular class, i.e. the limit
at which one class transitions into another.
• Maximum Permissible Exposure (MPE): Level of laser radiation to which, under normal circumstances, persons
may be exposed without suffering adverse effects.

laser product safety standards
If your product contains lasers, it has been designed and manufactured to comply with the international laser product
safety standard IEC 60825-1 and the U.S. CDRH Regulation 21CFR § 1040.10 to reduce risk as far as is reasonably
practicable. Our Customer Support Team, where applicable, install the system according to the same standards, but if
there has been an agreement that you should install all or part of the laser product system, then you take responsibility
to install this according to the same standards.
eye protection
Eye Protection is not required for the safe use of the device as the only radiation observable (without intentional
misuse) is directionally stable, diffuse and highly divergent from the designated aperture which is static and labelled.
If eye protection is deemed desirable by the local Laser Safety Ofcer, Andor recommends the following products:
• 360 nm to 510 nm – Kentek KXP-4001 Spectacles
• 510 nm to 670 nm – Kentek KRA 6702 Spectacles
Working WitH optical fibres
1. Only service personnel authorised by Andor should remove or inspect bres as these are part of the installed
protective housing
2. The laser radiation passing through bres is potentially hazardous, so great care should be taken to avoid
exposure to this radiation
3. Ensure bre cables are not bent tightly or general mishandled as this may damage the internal optical bre
4. Ensure that the minimum bend radius is never exceeded when handling, which is recommended to be 300
mm
5. For transport or storage, bre cables should be coiled with a diameter of 300 mm or greater
6. Optical bres are prone to damage by bending local to the connector
7. The coupler is not designed to withstand pulling of the bre. If the bre is pulled, the system performance
could be compromised or the system may fail
8. Locate the laser source and any other connected devices within 2 m of each other so that the interconnecting
bres are not stretched, bent, or constrained

The ‘maximum output’ dened by IEC 60825-1 § 3.58 and § 7.9 is “the maximum accessible emission that is used to
determine the class of the laser product”. Note that this is as measured using a 7 mm aperture stop at 100 mm from
the accessible aperture of the collimator as per Condition 3, which simulates eye exposure. However, the total optical

As the bre can be disconnected from the ME-OPT-0007 Collimator/Collector, laser radiation can be emitted from the
output, so it is labelled as a ‘Laser Aperture’. Although the output would be classied as Class 2 because it is typically
0.15 mW under IEC 60825-1 Condition 3, this is superuous as it is attached to a Class 3R product, the Laser Module.
Note the total optical power right at the output of the bre is higher, typically 1.65 mW.

SECTION 1: INTRODUCTION
Thank you for choosing the Andor Mechelle, which offers several innovations to the spectroscopist. The Andor
Mechelle spectrograph is based on the echelle grating principal and has a patented optical design, which gives
extremely low cross-talk, equally spaced order separation and maximum resolution, compared with other spectrographs.
The Mechelle offers a simultaneously recorded wavelength range from UV to NIR with very high resolution and no
overlapping wavelengths.
• The Mechelle features patented, corrected off-axis optics enabling the user to achieve maximum throughput
and optimum Gaussian line shape and resolution. This translates to a wide wavelength range from the deep
UV through to NIR, with full spectral continuity, no gaps and no overlapping wavelengths. You get the whole
spectrum in one single acquisition. The maximum wavelength range is set by the detector sensitivity and the
low wavelength limit is set by the absorption of air.
• The spectrograph has a rugged compact design with no moving parts, enabling the Mechelle spectrograph
to withstand more physical handling than other high performance spectrographs. This makes the Mechelle an
ideal spectrograph for OEMs and non-lab based applications, from zero gravity experiments to operation in high
temperature environments. The unit can also be evacuated for working in the deep UV.
• Andor have utilised many years experience in spectroscopy to deliver a software platform designed for
spectroscopists. The Solis software allows direct control over spectrograph functionally. A user-friendly on-
screen dashboard allows the user to acquire data, calibrate spectral displays, and manipulate post acquisition
data. The speed of the system is only dependent on the integration time, readout rate of the camera and the PC
capabilities.
• The Andor Solis software is also compatible with other spectroscopic data analysis like GRAMS/Al. Mechelle
spectrographs are integrated with CCD, sCMOS or ICCD detectors form Andor Technology, which enables
the user to rapidly obtain accurate data. This makes the Mechelle spectrograph highly attractive to many
spectroscopic applications like Laser Induced Breakdown Spectroscopy, Raman spectroscopy or Laser ablation.

Figure 1: The Mechelle spectrograph
Input Interface (Shutter Housing)
For coupling to optical source via a bre-optic and/or slit. A shutter can be built into the housing as an option (e.g.
for CCD cameras to avoid image smearing during readout or for ICCD cameras to take background or protect the
photocathode between experiments).
Shutter Cable Connection
For connection of the temperature sensor and optional shutter to the detector.
Carrying Handles
Two handles can be used to transport the Mechelle and fold down when not in use.
Camera Mounting Flange
For connection to camera e.g. Andor iStar CCD or sCMOS (4 off, 6/32 x 3/8 UNC).
Support Feet
Two support feet provide a stable platform for the Mechelle. These can be secured to an optical bench or removed.
