Versatile Laser Diode Module
Versatile Module
The VM (Versatile Module) from Imatronic provides a high quality and cost effect OEM solution to a
wide range of applications including Machine Vision, Inspection, Alignment and Positioning.
The module is a compact 11mm diameter and features output powers of 1 & 3 mW in both 650 &
635nm with the benefit of an isolated housing and reverse polarity protection as standard. An A/R
coated user adjustable collimating lens produces an elliptical output beam which can be focussed to
produce fine spots. A TTL enable input is also included as standard which allow the user to switch the
laser on and off with a TTL logic level signal.
Further versatility is provided by the wide range of external optics available which simply screws into
the end of the laser module, allowing the user to quickly and efficiently switch from one projection to
another. The range includes Homogeneous lines and cross’s and diffractive patterns.
A optional heavy duty clamp (HDC) allows the user to secure the laser and has parallel and vertical
adjustment which allows the user to aim the laser in any required direction or angle. The robust
aluminium construction also assists in conducting heat away from the laser body as well as preventing
movement due to shock and vibration. The base plate of the HDC has a series of threaded holes to
allow the HDC to be securely fastened to stable surfaces.

Modulation
A common requirement for applications which use photo detectors, cameras and other non-visual
sensing is the ability to rapidly switch the laser output ON and OFF. Simply applying and removing
the supply voltage is rarely satisfactory and in certain cases can result in the destruction of the
module. This is because laser diodes are very sensitive to spikes and surges, which are often the
result of uncontrolled supply switching. To overcome this limitation, the VM is supplied with an
additional inputs via a third input wire that controls the output of the laser module in a reliable and
predictable way.
TTL Enable Input
Some applications require a simple, slow speed ON/OFF switching. The VM eliminates the requirement
to provide an external switching device by providing a logic compatible enable input, capable of
operating from low power logic and micro-processors. In this OFF condition, the module draws
virtually no current and no light is emitted. Bandwidth is typically ≤1Khz. If not using this function
connect the lead to supply or the laser will not switch on.
Optional Projection Lenses
A range of projection lens which convert the beam into a pattern are also available for the VM.
The Interchangeable line and cross lens assembly’s consists of a moulded acrylic multi-rod
lens element. The lens produces a cross/line with an intensity distribution is gaussian in the
width and homogeneous in the line. The homogeneous line produces a line with high
uniformity at shorter working distances, however due to the effects of divergence the
uniformity levels will decrease over longer working distance.
The Grid lens assembly consists of a diffractive optical element (DOE) lens. The lens produces
a 4x4 grid pattern with typical full fan angle of 4.57° and the intensity distribution is Gaussian
in the width and homogeneous in the line. The distance between each line in the grid pattern
in typical 1.18°. The DOE produces a pattern with high uniformity at shorter working distances,
however due to the effects of divergence the uniformity levels will decrease over longer
working distance. The lens assembly to simply screw into the VM and converts the output
beam into the listed pattern.
