Description

LUXYR LED PICO – Compact Direct-Fit LED Illumination for Demanding Microscopy

The LUXYR LED PICO is a high‑performance, direct-fit LED light source engineered for modern fluorescence and brightfield microscopy. Designed as a compact replacement for conventional halogen or mercury lamps, it combines high radiant output with excellent illumination homogeneity in a form factor that integrates directly into the microscope’s illumination path. With versions spanning UV‑A to near‑infrared (365–735 nm) as well as high‑intensity white‑light models, this system provides a flexible platform for laboratories and OEMs looking to precisely match their light source to specific imaging tasks.

In contrast to traditional arc lamps, the LED PICO delivers instant-on operation, long service life, and stable output without warm‑up times or bulb replacements. Its collimation optics and dedicated microscope adapters are optimized for coupling efficiency and uniform field illumination across the specimen, making it suitable for both routine imaging and advanced quantitative applications. For users upgrading older microscopes, the direct‑fit design offers a straightforward path to LED illumination with minimal mechanical changes and no compromise in optical performance.

Broad Spectral Range from UV-A to NIR and High-Quality White Light

The LED PICO is available in monochromatic variants from 365 nm to 735 nm, covering UV‑A, visible, and NIR regions important for a wide variety of fluorophores and inspection tasks. Typical lines include 365 nm, 385 nm, 405 nm and other application-relevant wavelengths, each chosen to provide strong radiant power and narrow spectral output for efficient fluorophore excitation and reduced background. These discrete wavelengths make it easy to optimize contrast and signal‑to‑noise ratios in fluorescence microscopy, darkfield imaging, and specialized inspection workflows.

In addition to monochromatic options, the LED PICO is available as a powerful white‑light source with integral luminous flux up to 2500 mW and luminous output up to 800 lm. HighFlux White versions provide intense illumination for demanding brightfield and darkfield microscopy, while HighCRI White variants (up to CRI 90) are tailored for applications requiring accurate color rendering, such as pathology, life‑science imaging, and visual inspection. This combination of output power and spectral quality makes the LED PICO competitive with or superior to many conventional microscope illuminators in both research and industrial settings.

Precise Electronic Control for Continuous, Follow, and Pulsed Operation

A key strength of the LED PICO is its sophisticated electronic control, designed to support both stand‑alone use and tight integration into automated imaging systems. In continuous‑wave (CW) mode, the device operates with adjustable luminous flux and minimal light ripple (< 0.5 %), delivering stable, flicker‑free illumination for visual observation, long‑exposure imaging, and quantitative measurements. Brightness control is gamma‑corrected, so perceived intensity changes are smooth and linear from the user’s perspective, which is particularly helpful when reproducibility and fine intensity tuning are required.

For synchronized imaging or high‑speed acquisition, the LED PICO supports advanced triggering modes via a TTL interface. In Follow mode, the light output is level‑controlled by a TTL signal, offering fast rise and fall times (t10‑90 and t90‑10 < 2 µs) and signal runtimes under 1 µs, enabling precise coordination with camera exposure or scanning systems. In Pulse mode, edge‑controlled pulses can be configured with defined delay, pulse length, and luminous flux. Minimum pulse length is on the order of 10 µs with delays below 5 µs, making this light source suitable for time‑critical applications such as high‑speed fluorescence imaging, stroboscopic inspection, and triggered machine‑vision setups.

Flexible Integration and Silent Operation for Sensitive Environments

The LED PICO has been designed with integration flexibility in mind. It features a compact housing (approximately 134 mm × 85 mm × 97 mm) and a low weight of around 0.8 kg, making it easy to mount on a broad range of upright and inverted microscopes or to incorporate into custom optical systems. Interchangeable microscope adapters are available for major microscope brands such as Zeiss, Leica, Nikon, and Olympus, with the option for customized adapters to fit OEM or specialty instruments. Integrated collimation optics ensure that the light is efficiently directed through the microscope’s illumination path, reducing setup time and alignment effort.
