Advanced Optical Detection Technology

We specialize in high-performance optical systems, combining decades of engineering expertise with innovative hardware and software. As an ISO 13485 certified company, we ensure your quality standards are met through robust, ready-to-integrate technology. Our miniaturized confocal fluorescence detector offers lab-grade sensitivity in a compact form. It supports dual-channel detection, enables real-time surface and liquid measurements, and integrates easily into handheld or inline systems.

Miniaturized Confocal Optics – ​Lab‑Grade Sensitivity, Compact Size

Our micro-scale, confocal optical system delivers performance comparable to premium spectrometers—packed into a device the size of a credit card. Confocal optics ensure precise fluorescence measurement of liquids and surfaces, making FluoSens ideal for in-line, on-line, or handheld applications.

  • Single- or dual-channel options (up to 2 wavelengths simultaneous)
  • Laser-level sensitivity, but with LEDs for stable, low-voltage operation (5 V DC)
  • Robust housing protects against dust, humidity & EMI
  • Plug-and-play integration via PCB interface

Stable LED Excitation & Closed‑Loop Control

Instead of bulky lasers, our fluorescence detectors use high-power LEDs with precision control: High-power LEDs ensure strong excitation. Temperature drift is corrected via a reference detector for stable, long-term performance.

LED output stabilized via temperature-regulated feedback loop
Guaranteed low-noise signal (0–2.5 V) from integrated photodiode
EMI-shielded electronics for reliable optical detection

High Sensitivity & Easy OEM Integration

Intelligent electronics empower system compatibility:

Onboard memory stores calibration data & serial number
Interfaces: RS232 / RS485 for seamless OEM integration
Interchangeable modules for scalable system design
High product reliability with ISO 13485 certification

Design Decisions Saved for You

We replaced traditional off-axis setups (large lasers + precise alignment) with a confocal miniaturized LED solution, bringing lab-grade sensitivity to mobile, industrial, and diagnostic systems—without complexity or bulky hardware.

Miniaturized Optics

The core technology is a miniaturized, confocal optical beam that has been developed using state of the art simulation tools. The separation of excitation and emission is performed via a complex system of optical filters. Top of the line injection molding guarantees replicable high volume production resulting in an outstanding price/performance ratio.

Closed loop controlled excitation

The newest LED-technology replaces the traditional lasers and lamps used in lab-based fluorescence excitation and this is possible due to the enormous light power offered by today‘s LEDs. While LED-power is temperature dependent, this is compensated for by that use of an additional detector that regulates the power to an adjustable value. As a result, the detector provides a stable and long-term measurement signal.

Premium technology sensitivity and low-noise

The photodiode and a low noise analog lamp are integrated within the detector. This enables short signal paths and protection from electromagnetic compatibility (EMC) problems. The detector delivers a low noise (0-2.5V) output. The encapsulated module is quite simple to handle and can easily be integrated into OEM-systems just by plugging it into a printed circuit board (PCB).

Intelligent, processor-controlled electronics

Along with the basic measurement electronics, the detector also consists of a temperature sensor and a memory chip. This chip stores specific sensor data such as calibration values, serial number, scaling etc. Data communication is conducted via serial interface (RS232 or RS485). A superordinate system is able to read out data and can also be used for data processing. The detectors are therefore interchangeable.

What Is Fluorescence?

Fluorescence is a form of luminescence where a substance absorbs light at one wavelength and emits it at another. This phenomenon is widely used in life sciences, diagnostics, and materials science.

How It Works

When molecules absorb photons, their electrons are excited to a higher energy state. Upon returning to their original state, they release light—this is fluorescence
