PicoScale User Manual

1INTRODUCTION

Congratulations on your purchase of the SmarAct PICOSCALE interferometer! You have acquired

a powerful tool for displacement measurements with picometer resolution. We are convinced

that the innovative features will make working with the PICOSCALE a pleasant and remarkable

experience.

1.1 Preface

This manual contains user information for the SmarAct PICOSCALE system, which includes a

control box, various sensor heads, a Breakout-Box and an Environmental Module.

NOTICE

Read this manual carefully before operating the PICOSCALE for the ﬁrst time.

Special attention should be given to the material in chapter 2 "Product Safety",

which describes the secure handling of the PICOSCALE system.

1.2 Technical support

Should you experience any diﬃculties with your PICOSCALE system or need any technical in-

formation, please visit our web site: www.picoscale.com. Additional support can be obtained by

contacting our technical support at PicoScaleSupport smaract.com or by phone at +49 441 800 879

0. When communicating with our Technical Support, the Support Engineer responding to your

request will require the model and the serial number.

1 INTRODUCTION

1.3 Signal words and symbols in this manual

This manual may contain sections in which particular hazards are deﬁned or special attention is

drawn to particular conditions. These sections are indicated with signal words according to ANSI

Z-535.6 and safety symbols (pictorial hazard alerts) in accordance with ANSIZ-535.3 and ISO 7010.

1.3.1 Signal words

Four signal words are used in this documentation: DANGER,WARNING,CAUTION and NOTICE.

The signal words DANGER,WARNING and CAUTION designate the degree or level of hazard when

there is a risk of injury:

DANGER

Indicates a hazardous situation that, if not avoided, will result in death or serious injury.

Do not proceed beyond a DANGER notice until the indicated conditions are fully understood

and met. This signal word is to be limited to the most extreme situations.

WARNING

Indicates a hazardous situation that, if not avoided, could result in death or serious in-

jury. Do not proceed beyond a WARNING notice until the indicated conditions are fully

understood and met.

CAUTION

Indicates a hazardous situation that, if not avoided, could result in minor or moderate

injury. Do not proceed beyond a CAUTION notice until the indicated conditions are fully

understood and met.

The signal word NOTICE is used when there is a risk of property damage:

NOTICE

Indicates information considered important, but not hazard-related.

Messages relating to hazards that could result in both personal injury and property damage are

considered safety messages and not property damage messages.

PicoScale User Manual

1 INTRODUCTION

1.3.2 Symbols

The signal words DANGER,WARNING and CAUTION are always emphasized with a safety symbol

that indicated a special hazard, regardless of the hazard level:

This symbol is intended to alert the operator to the presence of important oper-

ating and maintenance instructions.

This symbol is intended to alert the operator to the danger of exposure to haz-

ardous visible and invisible laser radiation.

This symbol is intended to alert the operator to the presence of dangerous volt-

ages within the product enclosure that may be of suﬃcient magnitude to consti-

tute a risk of electrical shock.

PicoScale User Manual

2PRODUCT SAFETY

2.1 Optical safety

Because of its special properties, laser light poses safety hazards not associated with light from

conventional sources. The safe use of the lasers require that all laser users, and everyone near

the laser system, are aware of the danger involved. The safe use of the laser depends upon

the user being familiar with the instrument and the properties of coherent, intense beams of

light.

CAUTION

The PICOSCALE Controller contains an infrared diode laser with an output of

less than 0.2 mW at 1520 nm - 1580 nm (less than 0.3 mW for V1.4 and less than

0.6 mW for V1.4-HP) and red diode laser with an output power of less than 0.6

mW at 650 nm (no red laser for V1.4-HP).

Although the PicoScale is a Class Iproduct due to the low output power, it is

a good practice not to stare directly into the laser beam. Never use optical

instruments to observe the beam, this can cause serious eye damage.

Always use the PicoScale as intended by this manual!

PicoScale User Manual

2 PRODUCT SAFETY

2.2 Electrical safety

The SmarAct PICOSCALE controller contains hazardous voltages. Do not disassemble the en-

closure. There are no user-serviceable components inside. All units are designed to operate as

assembled. Warranty will be voided if the enclosure is disassembled.

WARNING

High voltage inside. To avoid electrical shock before powering the unit, make

sure that the protective conductor of the 3-conductor power cord is correctly

connected to the protective earth contact of the socket outlet. Improper ground-

ing can cause electric shock resulting in severe injury or even death.

WARNING

Shock warning. Do not operate without cover installed. Do not stick any mate-

rial through the ventilation holes. Do not operate under wet/damp conditions.

WARNING

Observe all terminal ratings. To avoid damage, ﬁre or shock hazard, observe

all ratings marked on the PicoScale Controller or documented in the manual.

NOTICE

High electrostatic charges readily accumulate in the human body and equipment

and can easily discharge without detection. Although the electronics features

have impressive input protection, permanent damage may occur on devices

subjected to high-energy electrostatic discharges. Therefore, proper ESD pre-

cautions are recommended to avoid performance degradation.

The most common ESD damage occurs while handling the device during instal-

lation or use. Take the necessary measures to protect the system from ESD, e.g.

by wearing a wrist strap.

Dry air and carpet can create an even higher potential for ESD. Precautions or

shielding need to be taken for demonstrations or trade show exhibitions.
