GUIDE OVERVIEW
This product guide is intended to provide functional, operational and installation
information for the Koheras BASIK MIKRO laser modules. The guide is divided
into three sections:
• Koheras BASIK MIKRO Description - introduces the laser, its functionality,
interfaces and chassis variants.
• Operating the laser – provides information and procedures on how to
connect and configure communications with the laser and manage its
operation.
• Installing the laser – includes the details on how to install the laser chassis
variants and connect optional interfaces.
Warning: Do not operate the laser before first reading and understanding all warn-
ings, cautions and handling information stated within the document:
Koheras BASIK MIKRO Safety, Handling and Regulatory Information
The paper copy of this guide is included with your laser however it can also be
downloaded from:
https://www.nktphotonics.com/lasers-fibers/support/product-manuals/
Terminology The guide may refer to the Koheras BASIK MIKRO modules as “the laser”. In
specific cases where a distinction is required, the guide will use the actual laser
model names or simply as “the module”.
Target audience This guide is for technical personnel involved in the selection, planning and
deployment of lasers in laboratory and industrial settings. The guide assumes a
reasonable knowledge level of lasers, photonic principles and electrical interface
connectivity.
Chapters inside This guide includes the following chapters:
• Chapter I “Laser description” — Describes the laser including its general
operational principles, management and interfaces.
• Chapter 2 “Communicating with the Laser” — Provides information and
procedures on how to setup a PC with the laser’s management software and
connect it to the laser.
• Chapter 3 “Turning On the Laser” — Contains procedures on how to safely
turn the laser emissions on and off using the management software.
• Chapter 4 “Using CONTROL” — Includes descriptions and procedures of all
other GUI menu and panel items.
4
• Chapter 5 “Software Development Kit” — Includes descriptions and
procedures for certain key settings that can be configured using the SDK.
• Chapter 6 “Mechanical Installation” — Includes information and procedures
on how to correctly install the laser chassis. Procedures within this chapter
focus on providing adequate temperature regulation.
• Chapter 7 “Connecting the laser” — This chapter provides the information on
how to physically connect the safety interlock, power, the optical collimator,
and the optional interfaces.
• Appendices — The guide includes multiple appendices including laser
specifications, support contact details, accessory descriptions, a
configuration ID cross-reference and miscellaneous procedures supporting
the laser operation and installation.
Added information
and safety notices
Lasers are highly dangerous devices that can cause serious injury and property
damage. This guide use the following symbols to either highlight important safety
information or provide further information in relation to a specific topic.
Note: Highlights additional information related to the associated topic and/or pro-
vides links or the name of the NKT guides describing the additional information.
Caution: Alerts you to a potential hazard that could cause loss of data, or damage
the system or equipment.
Warning: The laser safety warning alerts you to potential serious injury that may
be caused when using the laser.
