Properties
The LDM200 series of laser diode modules are specialized units for high-end applications. The fibre coupled design allows flexible installation and separation of the electrical and optical sections. High quality optics and precision adjustment provide for excellent beam quality and very long collimation distances up to 100m. Customized fixed focus distances may also be provided. The option of choice of polarization (unpolarized, linear or circular) is unique and provides many advantages in measurement reproducibility in metrological applications.
FIELDS OF APPLICATION
These compact, high quality, laser diode modules may be used for industrial metrology and machine alignment applications. The excellent beam quality provides for high reproducibility independant of module rotation. The rugged designs are adapted to industrial applications and provide for very high pointing stability. In OEM applications, the small size of the source allows for simple integration.

What is the LDM200 series?
The LDM200 series is a range of specialized, high-end fibre-coupled laser diode modules designed by Artifex Engineering for industrial applications such as machine alignment, machine vision, microscopy, surface analysis, and industrial metrology.
What makes the fibre-coupled design an advantage?
The fibre-coupled design separates the electrical and optical sections of the module, allowing for much more flexible installation. You can mount the optical head where you need the beam while keeping the driver electronics in a more convenient or protected location.
How good is the beam quality?
The LDM200 series delivers excellent beam quality thanks to high-quality optics and precision adjustment. This also provides high reproducibility that is independent of module rotation — an important factor for repeatable metrological measurements.
What is the maximum collimation distance?
Collimation distances of up to 100 m are achievable, making the module suitable for long-range alignment and positioning tasks.
Can I get a custom focus distance instead of a collimated beam?
Yes. Customized fixed focus distances can be provided on request, in addition to the standard collimated configuration.
What polarization options are available?
You can choose from unpolarized, linear, or circular polarization. This flexibility is fairly unique in the market and offers real advantages for measurement reproducibility in metrological applications.
How is the module controlled?
The module can be controlled either via the front panel directly or over USB, giving you flexibility for both manual bench use and automated/integrated setups.
What is the interface and how fast is the response time?
The module communicates over USB. Rise time depends on the model: 50 ns for fast rise time models, or 500 ns for long pulse models.
What output functions are supported?
The module supports staircase and burst output functions, among others, enabling flexible signal patterning for different applications.
How stable and accurate is the beam pointing?
Pointing stability is rated at ≤5 µrad/°C, and pointing accuracy is ≤0.5°, ensuring reliable performance even under varying thermal conditions.
What optical power and wavelength does the module operate at?
Typical fibre optical power is 5 mW minimum, with a peak wavelength around 658 nm (range 650–665 nm at Pf = 5 mW).
Is the module suitable for OEM integration?
Yes. Its compact size makes it easy to integrate into OEM systems, while its rugged design ensures high pointing stability even in demanding industrial environments.
Can I get a custom system built around this module?
Yes. Artifex Engineering can design complete custom systems — including laser or LED-based light sources and simple or intelligent driver electronics — built to your specification.
Does the module come with software or a development kit?
Yes. Every device purchase includes the free Artifex Software Development Kit (SDK). It contains the application source code (in VB.NET), a LabVIEW VI with the module’s basic functions, and documentation describing the communication protocol and command set.
What industries or applications is this module best suited for?
It’s built for industrial metrology, machine alignment, machine vision, microscopy, and surface analysis — anywhere that requires a precise, stable, and reproducible laser reference beam.
Artifex Software Development Kit
The SDK is a fixed, free component when purchasing a device.
It comes with the source code of the application program (in VB.net) and a LabView VI with the basic functions of the instrument. A description of the communication with the devices and a list of the commands used is also included.
