RAMAN SPECTROSCOPY APPLICATION

Raman Spectroscopy is a powerful analytical technique used to study vibrational, rotational, and other low-frequency modes in a system. It relies on inelastic scattering of photons, known as Raman scattering, to provide detailed information about molecular composition, structure, and interactions. The performance of Raman systems is significantly enhanced by the use of high-quality optical components such as optical filters and coated fiber tips. Omega Optical offers advanced solutions designed to meet the stringent requirements of Raman spectroscopy applications.

THE IMPORTANCE OF OPTICAL FILTERS IN RAMAN SPECTROSCOPY

Optical filters are critical in Raman spectroscopy for their role in managing and controlling the specific wavelengths of light used in the analysis. The key features of these filters include:

Portable Raman spectroscope

Bandpass Optical FilterOmega Optical’s filters are designed with extremely steep cut-on and cut-off transitions. This precision is crucial for accurately separating the Raman signal from the Rayleigh scattered light, which enhances the clarity and accuracy of the spectral data.

Our filters provide deep blocking of unwanted wavelengths, significantly reducing background noise and improving the signal-to-noise ratio. This deep blocking is essential for detecting weak Raman signals against a strong background of scattered light.

TYPES OF FILTERS USED IN RAMAN SPECTROSCOPY

Fluorescence Filters

Laser Line Filters

These filters are used to clean up the laser source, ensuring that only the desired wavelength reaches the sample. They are crucial for reducing the background noise and enhancing the sensitivity of the Raman system.

Notch Filters

Notch filters are designed to block the Rayleigh scattered light while allowing the Raman scattered light to pass through. They are essential for isolating the Raman signal from the intense laser line.

Longpass Edge Filters

These filters block the laser wavelength and transmit the Raman scattered light, ensuring that the lower energy (Stokes) Raman signals are effectively captured

Bandpass Filters

Used to select specific Raman bands of interest, these filters help in focusing on particular molecular vibrations and enhancing the specificity of the analysis.

Coated fiber tips for raman spectroscopy

Fiber tip Bandpass filter for Raman Our unique capability to pattern fiber bundles with bandpass, notch, and laser line filters enables for the miniaturization of Raman probes, enabling measurement of hard-to-access samples.

Coated fiber tips ensure that the maximum amount of Raman scattered light is transmitted to the detector, improving the overall sensitivity of the system.

coated fiber tipsOur fiber tip coatings are designed and manufactured to withstand harsh environmental conditions, ensuring long-term performance and reliability.

Key Supporting Capabilities

Solution

Our commitment to finding the right solutions for difficult problems means that we are capable of doing what other engineers cannot. Some say we bend physics and solve the unsolvable. Can we? Maybe. What we know we can do is this: We ask questions and we dig, because sometimes the solutions people believe they need only scratch the surface.

Solution

Omega coating heritage dates back to 1936, and spans a wide range of technologies: Sunglasses to space-borne sun-visors;  halogen light bulbs to COVID-fighting UV-C lamps, supermarket scanners to modern printers, astronomical mirrors to prestigious art installations to entertainment optics: if an application requires a precision or decorative coatings we surely have a proven solution.

Solution

We have the diffractive optics trifecta of multiple Ruling Engines, Holographic Mastering, and Lithographic exposure to create diffractive elements. Our in-house design and manufacturing processes provide standard or custom gratings for a range of applications, in both Original and Replicated formats.

Solution

We believe you cannot confidently make what you cannot measure, and therefore have invested in standard and custom metrology and inspection stations. Certified ISO 9001:2015. Lean manufacturing, including 6 Sigma methodologies and approaches to problem solving.
