Shape and Distance Measurement

Our extensive expertise in shape and distance measurement enables us to apply and integrate various optical measurement techniques in a targeted manner. We are experienced in developing systems applying optical coherence tomography (OCT), chromatic confocal sensors, laser triangulation, and laser distance measurement systems. This allows us to measure distances between components or lenses with the same level of reliability as we apply to the quality control of surfaces on even the most complex mechanical components. Embedded defect detection streamlines the inspection process.

Spectroscopy and Photometry

Some materials and chemical substances interact with light in a very specific manner. Spectroscopic methods are therefore particularly well-suited to the detection of substances, color analysis, and the characterization of coatings. Our team of experts develops spectroscopic sensors for specific measurement applications. Additionally, we utilize photometric measurement techniques for reflectance and transmission measurement, as well as color measurement (colorimetry) and color change determination (e.g., for chemical reactions or pH value measurements).

“By installing optical measuring systems from DIOPTIC, we are able to detect errors and inaccuracies early on in the production process. Furthermore, we now have the opportunity to determine key figures that we can use to improve our production processes.”

Fluorescence and Absorption

The use of dyes or contrast agents in medical diagnostics is becoming increasingly prevalent. Fluorescent markers, which are excited by light of a specific wavelength, enable a variety of detection methods, including: fluorescent labelling, fluorescence microscopy or fluorescent security marking. We also have expertise in detecting dye concentrations via absorption measurements. In these sensitive areas of medical diagnostics, we provide our customers with the support they need to develop fluorescence or dye-based measuring systems.

Laser and Light Measurement Technology

The optical measurement of light angles and light distribution or laser beam geometries is a highly specialized field. We are able to carry out angle measurements in-house (with an autocollimator), measure and align optical axes, check laser beam geometries with regard to divergence, diameter and focus position, and ensure eye safety in accordance with the laser safety standard DIN EN 60825-1. Our inspection systems play a critical role in verifying the optical system parameters of LIDAR (Light Detection and Ranging) modules.

Laser Triangulation for Measuring Lenses

Laser Triangulation for Measuring Lenses

In laser triangulation, a laser beam is directed at a measurement object and observed by a camera (lens + sensor). When measuring lens outlines and circumferences, triangulation sensors provide a spatially resolved distance measurement. The measurement data allows for the identification of various defects, such as scratches, cracks, splinters, or corrosion, according to a comprehensive and openly defined catalog of defects. In addition to the optical setup, DIOPTIC also oversees the programming and integration of the sensors.

PCR Analysis using Fluorescence

PCR Analysis using Fluorescence

Modern Polymerase chain reaction (PCR) analysis methods employ fluorescent markers to identify viruses with a high degree of specificity and selectivity. The challenge in optical system development in this case is that the fluorescence signals are often weak and easily influenced by external parameters. In addition, several different fluorescent markers are usually used simultaneously, making it challenging to differentiate them. It is therefore essential to carefully design the excitation and detection spectra to achieve precise detection.

LIDAR inspection with DIOPTIC conoscopes

LIDAR inspection with DIOPTIC conoscopes

In advanced driver assistance systems, LIDAR systems must detect objects and their direction of movement within milliseconds. It is crucial that the transmitter unit of the transceiver covers a sufficient angular spectrum; the transmitter and receiver units must be optimally aligned with each other. Our high-quality conoscopes ensure the correct alignment of the respective units as part of the LIDAR test. DIOPTIC's innovative concept can be individually adapted to the specifications of the respective LIDAR system.
