This expanded lineup introduces optical power meters, transimpedance amplifiers, and laser diode drivers, each engineered to elevate system performance and provide seamless integration into next-generation photonic setups:

OPM200: Reliable Mid-Range Optical Power Measurement

The OPM200 is purpose-built for mid-range optical power measurements, where stability and repeatability are paramount. Its wide spectral range enables measurements across common communication bands as well as visible wavelengths used in laboratory lasers and imaging sources. A high dynamic range allows users to capture both weak signals and moderately strong beams without swapping sensors, minimizing downtime during experiments or production testing. Advanced digital filtering suppresses electronic noise, while an intuitive interface and multiple data-output options - USB, Ethernet, or analog voltage - make it easy to embed in automated calibration rigs. For metrology labs or production environments that require traceable accuracy, the OPM200 offers long-term calibration stability and temperature-compensated electronics, ensuring consistent readings even when ambient conditions fluctuate.

OPM500: High-Sensitivity Optical Power Monitoring

Engineered for applications where every nanowatt counts, the OPM500 delivers enhanced sensitivity and faster temporal response compared to the OPM200. Its extended spectral coverage supports measurements from the deep visible into the near-infrared, accommodating both classical telecom windows and emerging quantum-communication wavelengths. With lower measurement uncertainty and rapid sampling rates, the OPM500 excels in capturing transient power changes from pulsed lasers, mode-locked sources, or high-speed optical modulators. Sophisticated auto-ranging electronics eliminate the need for manual range switching, while real-time data streaming enables direct integration with feedback loops in precision optical experiments. These features make the OPM500 a natural choice for quantum photonics, ultrafast spectroscopy, and cutting-edge telecom R&D. 

TZA200: Low-Noise Transimpedance Amplifier for Precise Signal Conversion

The TZA200 is designed to convert minute photodiode currents into clean, usable voltages with exceptionally low noise. In low-light or high-precision experiments - such as Raman spectroscopy, fluorescence lifetime measurements, or astronomical photometry - signal fidelity is everything. The TZA200’s carefully engineered input stage minimizes input-referred current noise and dark offsets, allowing the faintest optical signals to be detected without distortion. Flexible gain settings give researchers control over bandwidth versus sensitivity, while robust shielding and precision PCB layout guard against electromagnetic interference. Its compact form factor makes it ideal for modular instruments where space is at a premium.

TZA400: High-Bandwidth Amplifier for Fast Optical Signals

For applications that demand both high bandwidth and ultra-low noise, the TZA400 provides a significant performance step up from the TZA200. Offering higher transimpedance gain and a wider frequency response, it faithfully reproduces fast optical pulses and high-speed modulation signals, crucial for time-resolved spectroscopy, optical coherence tomography (OCT), or high-speed fiber-optic communications testing. Precision thermal design keeps drift to a minimum, ensuring that gain and noise figures remain stable over extended measurement sessions. With its combination of speed, sensitivity, and low noise, the TZA400 is an enabling component for state-of-the-art detector systems and next-generation optical instrumentation. 

LDD100: Precision Laser Diode Driver for Stable Optical Output

Artifex’s LDD100 series brings precise, stable current control to a wide variety of semiconductor laser diodes. Accurate current regulation - down to fractions of a milliamp - translates directly into stable optical output power, which is essential for telecommunications transmitters, LiDAR emitters, and high-resolution medical imaging systems. The driver incorporates fast rise-time circuitry for pulsed operation and advanced thermal management to protect delicate laser diodes from over-temperature conditions. Multiple control interfaces-digital, analog, and computer-programmable - simplify integration into both bench-top research setups and automated production equipment. Built-in safety interlocks and soft-start functionality further protect expensive laser sources from current spikes or power interruptions, giving OEMs and researchers a reliable platform for long-term deployment.

Together, these instruments transform Artifex Engineering from a specialist in precision passive optics into a full-spectrum photonics partner. The combination of premium BK7 glass elements with state-of-the-art measurement and control electronics enables researchers, OEMs, and system integrators to build stable, efficient, and scalable photonic systems that meet the most demanding requirements of modern science and industry.
