Overview

Venuslab™: Redefining Laboratory-Grade Precision Light Sources

The Venuslab™ Laboratory Precision Infrared/Optoelectronic LED Series represents the pinnacle of high-performance solid-state illumination technology, engineered to meet the rigorous demands of modern photonics research, biomedical instrumentation, and high-precision industrial sensing.

Unlike standard commercial-grade LEDs, the Venuslab series not only covers a vast spectral range from Ultraviolet (UV) and Visible to Near-Infrared (NIR) and Short-Wave Infrared (SWIR), but also delivers a qualitative leap in beam quality and radiometric stability.

This series features industrial-standard TO-18, TO-39, and T-1 3/4 hermetic metal or epoxy packages, integrated with high-precision glass lenses or parabolic reflectors. This optical design significantly enhances photon extraction efficiency, generating high-intensity output beams. Addressing the inherent divergence of LEDs, the Venuslab series is optimized to function either as standalone high-radiance point sources or to couple perfectly with Venuslab’s aspheric lens kits to output high-quality collimated parallel light, thereby solving the technical bottleneck of coupling traditional LEDs into optical fibers or spectrometers.

Detailed Applications

Optical Coherence Tomography (OCT)
Non-invasive Glucose & SpO2 Monitoring
Fluorescence Excitation
NIR Spectroscopy Analysis
Gas Sensing & Environmental Monitoring
Security & Night Vision Illumination
Fiber Optic Component Testing
Free Space Optics (FSO)

Usage & Storage Recommendations

Drive & Thermal Management: LEDs are current-driven devices and must be powered by a Constant Current Source. For high-power models exceeding 100mA (e.g., TO-39 packages), it is recommended to mount them on aluminum or copper heat sinks to prevent junction temperature rise, which can cause wavelength drift or lifetime degradation.

ESD Protection: Infrared LED chips are sensitive to electrostatic discharge. Always wear anti-static wrist straps when handling and ensure soldering equipment is properly grounded.

Optical Cleaning: If dust accumulates on the glass lens surface, gently wipe it with anhydrous ethanol and optical lens paper. Do not use rough cloths to avoid scratching the lens surface and degrading beam quality.
