Advanced holographic technologies for research, industry, and government applications
Holography for Precision Applications
At the core of Rayvel’s vision is the role of holography in industrial, scientific, and government applications. Rayvel develops advanced holographic technologies designed to support precision measurement, secure authentication, and high-performance optical systems across a wide range of disciplines.
Our products and solutions are engineered to meet demanding technical requirements in research, manufacturing, infrastructure, and public-sector environments.
Government Authentication & Security
The authenticity of government-issued identification, documents, license plates, and official markers can be ensured through the application of holographic laminates and seals. These security elements are extremely difficult to replicate and can include hidden features when maximum protection is required.
Holographic technologies can also encode information directly into documents, enabling secure access to data such as medical or identification records.
Automated Optical Test Stations
Rayvel’s OTS 2000 Automated Optical Test Station fully characterizes the performance of large optical flats — including TV, monitor, tablet, and mobile device displays — through a fully automated testing process.
- Detection of defects as small as 1 micron
- Automated defect mapping and quantitative reporting
- High-accuracy servo-driven translation stages for long-term production use
- Integrated safety features to prevent optic damage
- Motorized XY stage with dual-camera inspection system
- Intuitive software designed for technicians with minimal training
- Modular architecture allowing future test expansion or customization
The OTS 2000 can be tailored to meet the exacting requirements of advanced applications, including photonic crystal generation.
Holographic Diffraction Gratings
Diffraction gratings separate light into its spectral components, similar to a prism, but with significantly higher efficiency. These components enable a wide range of scientific and industrial applications, including telecommunications, spectroscopy, astronomy, and microscopy.
Rayvel specializes in the development of custom holographic diffraction gratings, engineered to meet the specific performance requirements of each application.
You will see more details of some gratings arrays below.
Optical Networking & Communications
Modern optical communications systems transmit audio, video, text, and data through information encoded on light signals. Technologies such as Wavelength Division Multiplexing (WDM) and Dense Wavelength Division Multiplexing (DWDM) allow multiple data channels to travel through a single optical fiber.
Diffraction gratings play a critical role in these systems by enabling precise filtering and switching functions. Components utilizing diffraction gratings include:
- Add-Drop Multiplexers
- Signal monitors
- Dispersion compensators
- Gain flatteners
Analytical Spectroscopy
Photonics enables non-destructive testing of liquids and gases through spectral analysis. In these systems, laser light passes through the test medium and reflects off a diffraction grating. A detector captures the reflected signal and generates a unique spectral “fingerprint.”
This fingerprint allows identification of the chemical composition of the tested material. Such systems are commonly used by:
- Biomedical researchers
- Utility providers
- Government agencies
- Environmental consultants
Microscopy & Nanotechnology
The rapid advancement of nanotechnology has increased the demand for detecting and analyzing structures at the atomic and molecular level. Diffraction gratings can serve as alternatives to traditional optical components, offering greater precision and enhanced measurement capabilities in advanced microscopy applications.
Astronomical Observation & Research
When used with telescopes and spectrographs, diffraction gratings enable detailed analysis of celestial bodies. By measuring light intensity across wavelengths, scientists can determine a star’s composition, motion, temperature, magnetic fields, and even detect atmospheric characteristics of distant planets or the velocity of supernova events.
