• Integrated Liquid Lens Provides Dynamic Autofocus
• 1,1” Sensor, Up to 12 MegaPixels, 3,45 μm Pixel Size
• Maximizes the Liquid Lens Performance for Resolution, Range and Focus Speed
TECHSPEC® LT Series Fixed Focal Length Lenses feature a high-resolution f/2,8 optical design with an integrated
Optotune liquid lens for fast electronic focus. The increased light throughput f/2,8 aperture is ideal for
high-speed machine vision applications. When combined with an appropriate camera and software, the focus
tunable liquid lens provides the active focus control needed to achieve an autofocus solution. These C-Mount
lenses are optimized for 1,1” sensors and have front fi lter threading to integrate imaging fi lters to meet application
requirements. TECHSPEC LT Series Fixed Focal Length Lenses are ideal for machine vision and factory
automation applications where focusing at multiple distances is required, such as quality inspection systems,
rapid automation, and package sorting. Note: Hirose cables (#88-941) and Lens Driver (#88-940) are required
for operation and sold separately.

TECHNICAL NOTE
Applications of Liquid Lenses
The adaptability, speed, and versatility of liquid lenses make them ideal for a variety of machine vision,
life science, and measuring and inspection applications. Due to their traditional mechanical layout,
standard machine vision lenses struggle to capture sharp and accurate images in high-speed or precise
applications that require quick refocusing.
Life Sciences: Liquid lenses improve and simplify the process of focus stacking (“z-stacking”) in microscopy
imaging applications. Focus stacking is often required when imaging with high magnifi cation
objectives due to their limited depths of fi eld. A liquid lens can quickly and precisely focus to various
object planes, therefore expediting the process of focus stacking. Liquid lenses can be easily integrated
into tube lenses or in infi nity space within a microscope.
Machine Vision: High-volume assembly lines require fast, accurate, and precise throughput. Integrating
a liquid lens into an inspection system is an optimal, compact, and economical solution when focusing
at multiple distances is required. Liquid lenses are an ideal solution for barcode inspection, package
sorting, quality control, and rapid automation.
Unmanned Aerial Vehicles: By adding a liquid lens to an unmanned aerial vehicle (UAV) imaging
system, image sharpness is quickly maintained across various heights. Liquid lenses are especially advantageous
in agricultural inspection and monitoring, geographic information systems, and in surveillance
applications.
Measurement and Dimensional Rendering: When paired with a distance sensor and camera, a
liquid lens can quickly image diff erent planes of a 3D object. The images are then stitched together in
software to create an accurate three-dimensional rendering.
As shown in the example of a typical inspection system, objects
of different heights are imaged as they pass by on a fast-moving
conveyor belt. A standard imaging lens requires mechanical
refocusing per every object, causing a delay that can limit highthroughput.
A liquid lens, free of mechanical translation, overcomes
these speed and depth of fi eld limitations by refocusing to
different heights in the matter of milliseconds.
