LTLA series

High-power strobed LED low angle diffused ringlights

Catalog 2019

LTLA series offers high-power diffusive LED strobed low-angle ring light illuminators designed to provide darkfield lightning and to effectively enhance minute surface features or textures.

LTLA series features ultra-high power light output and can be used to cast shadows that emphasize surface irregularities, scratches or special characteristics (such as bar codes) from a close distance.

LTLA low angle ring illuminators can be exclusively operated in strobe mode, making them the perfect choice to illuminate very fast moving objects while ensuring extended LED lifetime since no heat is generated.

LTLA series can be easily powered, controlled and synchronized by compatible LTDV strobe controllers and is available in:

two sizes: medium and large, respectively with illumination area of 60 mm and 100 mm in diameter;
two power intensities: medium power with driving current up to 7.5 A and high power with driving current up to 17 A;
three different colors: white, red and green.

LTLA series feature industry standard connection (M12 four poles connector) and can be easily integrated into any machine vision system by means of M6 screws.

KEY ADVANTAGES

Ultra-high power light output and strobe mode only operation
For the inspection of fast moving object and extended LED lifetime.
Rugged industrial design with built-in industrial connector
For easy integration into any machine vision system.
Wide selection
Available in two sizes, three colors and two power intensities.
Low angle beam shaping diffuser
Highly diffusive material avoids hot spots formation and ensures uniform light intensity.

Easily power, control and synchronize

Ordering information

It’s easy to select the right illuminator for your application: our part numbers are coded as LTLAxy-z, where x defines the illuminator size (B = medium, C = large),
y refers to the power intensity (1 = medium, 2 = high) and z refers to color (W = white, R = red, G = green).
For instance LTLAB2-R is a diffusive strobed low angle ring light illuminator - medium size high power red.
