Chapter 2 Safety

2.1. Precautions

Please read the instruction manual carefully before operating your Spatial Light

Modulators. All statements regarding safety and technical specifications will only

apply when the unit is operated correctly.

Refer to this User’s Guide whenever the following symbols are encountered on the

Spatial Light Modulators.

DO NOT OPEN HOUSING

Thorlabs’ SLM has no user-serviceable parts. Service should only be performed

by trained service personnel.

SHOCK WARNING

High voltage inside. To avoid electrical shock, before powering up, make sure that

the ground pin of the power cord is correctly connected to the ground connector

in the power socket. Improper grounding can cause electric shock resulting in

severe injury or even death. Do not operate without the cover installed.

WARNING

This unit must not be operated in explosive environments. Do not operate in

wet/damp conditions. Do not obstruct the air ventilation slots in the housing.

WARNING

Transportation and delivery may cause the SLM to be warm or cool upon receipt.

Please wait for the whole device to reach room temperature before attempting to

operate.

Rev F, December 7, 2020 Page 3

2.2. Product Care

Handle the complete system with care during transportation and unpacking.

Banging or dropping the system can damage the unit or lower the system

performance. If this occurs, the complete system will need to be sent back for

recalibration. Please contact Thorlabs Technical Support for more information.

•Do not store or operate in a damp, closed environment.

•Do not store or operate on surfaces that are susceptible to vibrations.

•Do not expose to direct sunlight.

•Do not use the solvents on or near the equipment.

•Mobile telephones, cellular phones, or other radio transmitters should not

be used with a range of 3 m of this unit since the electromagnetic field

intensity may exceed the maximum allowable disturbance values,

according to EN50082-1.

•Keep away from dust, dirt, and air-borne pollutants (including cigarette

smoke). The system is not designed for outdoor use. Protect the

equipment from rain, snow, and humidity.

•Do not expose to mechanical and thermal extremes. Protect the

equipment from rapid variations in temperature.

•Handle all connectors with care. Do not use unnecessary force, as this

may damage the connectors.

•Handle the mainframe with care. Mishandling may cause the body injury.

•Clean the protective window by using a soft, lint free cloth. Use of

isopropyl alcohol is permitted; however, do not immerse in any liquid or

solvent.

•Clean any accessible optical surfaces with an appropriate optics grade

tissue or cloth.

2.3. Service

CAUTION

Except for the main fuse, which is accessible from the outside of the housing, the

EXULUS®SLM has no user-serviceable parts. Service should only be performed

by trained service personnel.

Only trained and approved Thorlabs’ personnel should service the system. Please

contact Thorlabs Technical Support at techsupport@thorlabs.com and a member

of our team will be happy to assist you.

2.4. Accessories and Customization

Although the system is easily adapted for custom interfaces, to achieve the listed

specifications, this system should only be used with accessories provided by

Thorlabs. Any modification or servicing by unqualified personnel renders the

warranty null and void, leaving Thorlabs free of liability.

Custom version with panel and controller in separate units available, please

contact Tech Support for questions on customization.

Chapter 3 Introduction

This manual provides instruction on how to install and operate a Thorlabs

EXULUS-HD2, EXULUS-HD2HP, EXULUS-HD3, EXULUS-HD3HP, or EXULUS-

HD4 2D Spatial Light Modulator (SLM). To ensure correct usage, read this manual

carefully before operating your EXULUS®.

3.1. Overview

Thorlabs’ EXULUS®SLM is a reflective SLM based on Liquid Crystal on Silicon

(LCoS) technology. It offers individually addressable pixels of phase shift or

retardance and provides large phase stroke and excellent phase stability.

Therefore, the EXULUS®SLM is ideal for many beam manipulation applications

including optical trapping, beam steering and shaping, femtosecond pulse

shaping, adaptive optics, imaging applications, holography, interferometry, laser

processing, lithography, and others.

3.2. Principle –Liquid Crystal on Silicon (LCoS)

The Liquid Crystal on Silicon (LCoS) technology is a reflective retarder panel

utilizing a liquid crystal layer sandwiched between a top transparent and

conductive ITO layer, and the reflective electrode layer on the bottom. On the

bottom layer, pixels are arranged as individual addressable aluminum electrodes.

Together with the ITO layer on top, an electric field is built by applying a voltage

between the two layers. The liquid crystal modules align according to the direction

and strength of the electric field. Since liquid crystal is a birefringent material, the

alignment of the liquid crystal modules in turn determines the retardance or phase

shift of each pixel.

3.3. Parts List –Accessories

The EXULUS®SLM is thoroughly tested and carefully packed at the factory. The

complete package varies according to the EXULUS model. Standard SLMs

(EXULUS-HD2, HD3, and HD4) consist of a main unit with a built-in SLM panel

and relevant accessories. The High-Power SLMs (EXULUS-HD2HP and HD3HP)

contains a main unit, an adapter board, an SLM head, and additional accessories.

The adapter board and SLM head are pre-installed on the main unit.
