TOPAG offers a wide range of laser diode modules with different output power wavelength combinations and many customization options.

Standard series laser modules

  • LM series designed for OEM applications where longevity, economical price and small size are important requirements.
  • LDL and LDH series show all features of industrial grade modules including high quality laser diodes, aspherical glass collimator, low power consumption, anodized aluminium housing and reverse polarity protection.

Peltier-cooled laser modules

  • LDT laser modules for highest requirements in bioanalytics, spectroscopy, particle analysis and other measurement applications. These modules include active temperature stabilization (TEC) and power adjustment. Optionally, TTL modulation up to 1 MHz is available.

Computer-controlled laser modules

LDC modules are compact computer-controlled lasers with integrated laser head and control electronics. Output power, TEC temperature and variable modulation up to 1 MHz can be set via RS-232 / USB interface or manually using push buttons. The built-in LCD display shows laser operating parameters. These modules demonstrate excellent beam quality, power stability, temperature control and low noise for demanding applications.

Customization Options

  • Custom electronic drivers with firmware and software
  • Mechanical design
  • Fiber-coupled versions (multimode, single mode and polarization-preserving)
  • TTL modulation
  • Other wavelengths
  • Cable length
  • Connector
  • Supply voltage
  • Working distance
  • Projection Patterns (DOE), for more details please see our datasheet on Pattern Generators
