Telecentric Lights


High-performance telecentric illuminators : LTCLHP series

LTCLHP series are high-performance telecentric illuminators specifically designed to back illuminate objects imaged by telecentric lenses. This high performance series provides:

  1. Excellent illumination stability featuring no light flickering thanks to very high current stability over time even at low currents.
  2. Precise light intensity tuning thanks to the leadscrew multi-turn trimmer positioned in the back.
  3. Easy LED source replacement and alignment for all the LED colors offered by Opto Engineering®.

LTCLHP telecentric illuminators offer higher edge contrast when compared to diffused back light illuminators and therefore higher measurement accuracy. This type of illumination is especially recommended for high accuracy measurement of round or cylindrical parts where diffusive back lighting would offer poor performances because of the diffuse reflections coming from the edges of objects under inspection.

Light paths with LTCL alignment

KEY ADVANTAGES

  • Complete light coupling
    All the light emitted by a LTCLHP source is collected by a telecentric lens and transferred to the camera detector, ensuring very high signal-to-noise ratios.
  • Border effects removal
    Diffused back-illuminators often make objects seem smaller than their actual size because of light reflections on the object sides, while collimated rays are typically much less reflected.
  • Field depth and telecentricity improvement
    Collimated illumination geometry increases a telecentric lens natural field depth and telecentricity far beyond its nominal specs.
  • Homogeneity test report with measured values

NEW

LTCLHP series is now also available with new LTSCHP1W-GZ green light source, suitable for any kind of sample and specifically tailored for measuring reflective objects and objects with sharp edges.

KEY FEATURES

  1. Reduction of edge diffraction effects
  2. Enhanced illumination uniformity, especially on large FOVs
  3. Less sensitive to alignment

Ultra compact telecentric illuminators : LTCLHP CORE series

LTCLHP CORE Series are ultra compact telecentric illuminators.They are up to 60% more compact than other collimated illuminators on the market.

The ultra compact size allows to greatly reduce the size of your machine and to easily integrate true collimated illumination instead of common flat backlights, thus improving your system’s performance.

The smart design also makes them easy to retrofit into existing systems. They can easily be mounted in different directions using any of their 4 sides, with or without clamps.

A smaller system means lower manufacturing, shipping and storage costs, as well as less use of factory space and is the solution preferred by the industry.

LTCLHP CORE illuminators can be used both with classic telecentric lenses and with ultra compact telecentric lenses from CORE family like TC CORE, TC2MHR CORE and TC4MHR CORE series.

KEY ADVANTAGES

LTCLHP CORE telecentric illuminators are up to 60% shorter than other telecentric illuminators on the market.

Space-saving telecentric illuminators for large FOV systems : LTCLHP CORE PLUS series

LTCLHP CORE PLUS telecentric illuminators are designed to illuminate large areas in a reduced space. They are up to 40% shorter than other telecentric lights on the market.

The length and working distance of a telecentric lens strongly impact the size of a vision system. Their working distance range has been optimized to make a measurement system as compact as possible, allowing to reduce the overall system’s dimensions by up to up to half.

The super compact form factor allows you to easily integrate CORE PLUS collimated illumination where classis telecentric lights don’t fit instead of common diffuse backlights, thus improving your system’s performance.

LTCLHP CORE PLUS lights have been designed for smart integration. They feature a built-in mounting flange so no additional clamps are required.

KEY ADVANTAGES

  • Large illumination area in a super compact form factor
    LTCLHP CORE PLUS are up to 40% shorter than other telecentric lights on the market.
  • Reduce the size of your vision system
    The working distance of LTCLHP CORE PLUS telecentric illuminators has been optimized to reduce the overall system’s footprint.
  • Boost your measurement system’s performance
    LTCLHP CORE PLUS illuminators may be used in place of flat backlights to improve your system’s performance.
  • Smart integration
    LTCLHP CORE PLUS illuminators integrate a mounting flange for easy integration without additional clamps.
  • System compactness is a competitive advantage
    A smaller vision system or measurement machine is preferred by the industry.

Flat telecentric illuminators for linescan cameras : LTCL4K series

LTCL4K telecentric illuminators are specifically designed to be paired with TC4K telecentric lenses, in order to provide the high optical throughput needed for high-speed linescan measurement applications involving for instance steering components, gear and cam shafts, grinding and turning parts.

These illuminators are equipped with state-of-the-art LED driving electronics, providing exceptional illumination stability, precise light intensity tuning and easy replacement of the LED source.

The unique “slim” form factor allows these units to be used in constrained spaces, often a critical factor in many industrial environments. Also, CMMR deflecting mirror accessories can be integrated to quickly assemble different illumination geometries, compatible with most type of inspection configurations.

Also, CMMR4K right angle mirror attachments can be integrated to quickly assemble different illumination geometries, compatible with most types of inspection configurations.
