1About this Document
This document is user guide of sensors LCI401, LCI1200, LCI1201 and LCI1600. Sensors LCI1220 and
LCI1620 are covered by separate guide. FocalSpec Software Development Kit (FSSDK) and the API
documentation can be found after FSSDK installation from folder: C:\Focalspec\FocalSpec Software
Development Kit\Manual.
2Safety Information
This chapter contains important safety information for installing and using the LCI sensors LCI401,
LCI1200, LCI1201 and LCI1600.
•Note! Read this document carefully before use.
•Note! Keep this document for future reference.
•Note! Original instructions. The original language is English.
2.1 Safety Notes
This document uses safety notes as follows:
•Note! Notes are tips, shortcuts or alternative approaches to the task at hand. Ignoring a note
should have no negative consequences.
•Caution! A Caution statement alerts you to situations that can be potentially hazardous to you or
cause damage to hardware, firmware, software, or data.
•Warning! A Warning statement indicates conditions or situations that can be potentially lethal or
extremely hazardous to you. Safety labels are also attached directly to products to warn of these
conditions or situations.
2.2 Warnings
•Caution! Do not remove any safety devices or open the cover. Risk of injuries and insecure
operation. The warranty is void if the cover is opened.
•Caution! Do not look directly into the light source. Light radiation may damage your eyes.
•Caution! This is a high-precision optical instrument. Protect the device from dust and moisture
and avoid subjecting it to shocks and strong forces.
•Caution! Before using the sensor for the first time, check the sensor for transport damage. If the
sensor is damaged, contact support. See Support.
•Warning! Use only qualified personnel for the installation of all electrical supplies and fixtures,
and make sure that all installations adhere to local regulations and safety standards.

2.3 Proper Use
The LCI sensor is designed for use in industrial areas. The sensor is used for optical measurements, such
as 3D topography, dimensions and distances measurements, measuring the tomography of transparent
materials, surface micro profile measurements, and film thickness measurements.
Use the sensor only in such a way that, in the case of malfunction or failure, personnel or machinery are
not endangered.
Ambient temperature range: +15 ºC … +35 ºC.
2.4 CE Marking
The manufacturer has confirmed that this product complies with the essential requirements of the
applicable EC Directive, based on the following specifications. Be sure to consider the following
specifications when using this product in the Member States of European Union.
•EMC Directive (2004/108/EC)
oEN55011 Class A ISM Conducted Emissions
oEN55011 Class A ISM Radiated Emissions

3Functional Principle
FocalSpec line confocal imaging (LCI) sensors measure and evaluate 3D profiles on a variety of different
target surfaces. LCI sensor technology provides precise and accurate microtopographic surface height
information based on chromatic confocal imaging principle.
Figure 1. Line confocal imaging illustration
LCI technology utilizes a broad band spectrum of light with a continuous band of wavelengths. By using
special lenses, a spectrally dispersed beam of light is projected onto the target surface for a short duration
of time for each acquired sample. The optical system then collects the reflected beam onto a highly
sensitive sensor matrix. In addition to vertical distance information (z-axis), the sensor provides lateral (x-
axis) distance information from 2048 sensor pixels. These measured 2048 x- and z-coordinates are then
output to a computer. In the case of a moving object, or traversing alternatively the sensor, an object can
be scanned over and all spatial dimensions of the object can be determined.
