Thorlabs PM400 Handheld Touchscreen Optical Power Meter Console

Description

Overview

The Thorlabs PM400 is a handheld touchscreen optical power and energy meter console that pairs with Thorlabs’ full range of interchangeable power and energy sensors, combining the field-proven PM100D measurement platform with a modern color touchscreen interface for faster, more intuitive operation. Seven Star LLC supplies the Thorlabs PM400 across Oman and the GCC as part of its genuine Thorlabs catalog, giving regional photonics laboratories, universities, and industrial optoelectronics facilities a dependable local source for authentic Thorlabs measurement instrumentation with responsive technical support.

Photonics engineers and lab technicians select the Thorlabs PM400 whenever a project calls for a touchscreen-driven power meter that speeds up day-to-day laser alignment and measurement work compared with a traditional button-and-menu interface, while retaining full compatibility with the established Thorlabs S-series sensor family.Seven Star LLC supplies this item on request with the manufacturer documentation, and availability and lead time are confirmed at quotation.

Measurement and Working Principle

The Thorlabs PM400 reads optical power or energy directly from any compatible Thorlabs sensor connected through its standard sensor interface, automatically recognizing the attached photodiode, thermal, or pyroelectric sensor head and loading its calibration data without manual configuration. Internally, the console applies wavelength-dependent responsivity correction so the displayed reading reflects true optical power across the sensor’s calibrated spectral range, while its bright color touchscreen presents live numeric readings, a configurable analog bar graph, and trend graphing in a single glanceable view. Touch-driven navigation on the Thorlabs PM400 lets a technician switch between power, energy, and statistics views, zero the sensor, and adjust averaging and wavelength settings directly on screen, without stepping through a multi-level button menu.

Engineering Design of the console

Housed in a rugged handheld enclosure with a bright color touchscreen display, the Thorlabs PM400 is built for both bench-top use and field alignment work where a full computer-connected measurement setup is impractical. The console includes a standard 9-pin D-type sensor input compatible with the complete family of Thorlabs S-series power and energy sensors, along with a USB interface for direct connection to a PC running Thorlabs’ Optical Power Monitor software for data logging, graphing, and remote control. The console supports user-adjustable wavelength correction, adjustable averaging, and configurable analog and digital filtering, and its non-volatile memory retains settings between power cycles so a technician can return to a saved measurement configuration instantly. A rechargeable battery pack keeps the Thorlabs PM400 fully portable for field alignment and site commissioning work away from a bench power outlet.

Key Features

  • The console automatically recognizes any connected Thorlabs power or energy sensor and loads its calibration data without manual setup.
  • The Thorlabs PM400 provides a bright color touchscreen with numeric readout, analog bar graph, and trend graphing for real-time laser alignment.
  • The console includes USB connectivity for PC-based data logging and remote control through Thorlabs’ Optical Power Monitor software.
  • The Thorlabs PM400 supports wavelength correction and adjustable averaging for accurate readings across a sensor’s calibrated spectral range.
  • This handheld power meter console runs on a rechargeable battery pack, making it fully portable for field alignment and site commissioning.
  • This Thorlabs measurement platform uses touch-driven navigation for faster access to power, energy, and statistics views than a traditional button interface.

Industrial Applications

The console is widely used in photonics research laboratories, university optics departments, and applied physics facilities across Oman and the GCC for day-to-day laser power verification, sensor characterization, and optical system alignment where a fast, touch-driven interface speeds up repetitive measurement tasks. In fiber-optic communications and testing environments, the Thorlabs PM400 supports transmitter power verification and insertion-loss measurement when paired with the appropriate Thorlabs sensor head, giving network technicians a portable, self-contained alternative to bench-mounted power meters. Laser processing and materials-science facilities also rely on the Thorlabs PM400 to confirm delivered laser power at the workpiece before running a cutting, welding, or marking process, helping protect both product quality and operator safety.

Because the Thorlabs PM400 works with the entire Thorlabs S-series sensor family, research groups across the region standardize on a single console and build out a shared pool of interchangeable sensor heads for different wavelength ranges and power levels, reducing the number of separate instruments a lab needs to purchase and maintain. With fast quotation turnaround and technical support, Seven Star LLC supplies the Thorlabs PM400 to laboratories, industrial facilities, and research institutions throughout Oman, Muscat, and the Sohar and Salalah economic zones, with lead time confirmed at quotation.

Educational and training laboratories in Omani and GCC universities also deploy the Thorlabs PM400 in optics and photonics coursework, since its touchscreen interface is intuitive for students while still delivering laboratory-grade measurement accuracy.

System integrators commissioning laser-based inspection, alignment, or measurement systems across the region use the Thorlabs PM400 as a portable verification tool during installation and periodic maintenance visits, confirming that a laser source is still delivering its specified power before returning automated equipment to production service.

Seven Star LLC’s Thorlabs catalog, including the PM400, gives regional photonics buyers a single trusted local partner for optical power meters, laser diode controllers, motorized positioning controllers, and related laboratory instrumentation, simplifying procurement for multi-vendor lab setups that previously required importing individual items from overseas suppliers.

Ordering Thorlabs items: what we need

Thorlabs item numbers are exact, so PM100D, PM400 and PM100USB are different products, and a console is normally ordered with a separately numbered sensor. Send the item numbers and quantities. For a power meter, add the wavelength, the power or energy range and the beam size, so the sensor can be checked. For laser diode drivers, give the diode pin configuration, the operating current and the TEC current. For motion controllers, name the actuator or stage to be driven. Mention the mains voltage and plug type you need.
