Fourier Transform Infrared (FT-IR) Spectroscopy is a pivotal technique in modern analytical science, enabling precise identification and quantification of materials. At the heart of FT-IR lies the principle of transforming infrared light into detailed spectral data, providing insights into the molecular composition of samples. Omega Optical is at the forefront of this technology, offering cutting-edge solutions that enhance the capabilities of FT-IR instruments.
Optical filters play a crucial role in FT-IR spectroscopy by selectively transmitting desired wavelengths and blocking out unwanted ones. Our filters are designed to optimize signal-to-noise ratios, ensuring that only relevant spectral information reaches the detector. With a range of custom filters tailored for specific applications, Omega Optical helps you achieve the highest level of precision and accuracy in your FT-IR measurements.
Diffraction gratings are essential components in dispersing light into its constituent wavelengths. In FT-IR spectroscopy, they allow for the separation of complex infrared signals into detailed spectra. Our diffraction gratings are engineered to provide high efficiency and resolution, ensuring that even the most subtle spectral features are discernible. This precision enables researchers to uncover intricate details about their samples.
Polkadot beamsplitters are used Fourier Transform Infrared (FT-IR) Spectroscopy, where they function by dividing the incident infrared light into two paths—one directed towards the sample and the other towards a reference. This division allows for simultaneous measurement of the sample and reference signals, enhancing the accuracy and efficiency of the spectral data collection. The polkadot pattern, with its precise distribution of reflective and transmissive regions, ensures consistent and uniform splitting of the infrared light. This uniformity is crucial for maintaining the integrity of the interferometric measurements, leading to highly accurate and reliable FT-IR spectroscopic analysis.
Omega Optical offers a variety of advanced infrared optics from specialty materials which enhance the performance of FT-IR instruments:
- Potassium Bromide (KBr): Known for its wide transmission range and minimal absorption in the infrared region, KBr is a preferred choice for high-precision applications.
- Cesium Iodide (CsI): With its excellent transparency and low refractive index, CsI is ideal for specialized infrared applications.
- Germanium (Ge): Germanium provides high refractive index and low dispersion, making it suitable for lenses and windows in infrared systems.
- Zinc Selenide (ZnSe): Offering broad transmission and high resistance to thermal shock, ZnSe is a versatile material for infrared optics.
- Zinc Sulfide (ZnS): ZnS is valued for its high transmission and durability, suitable for demanding environments.
Our proprietary infrared coatings seal these hygroscopic crystals, protecting them from moisture and extending their operational lifespan while simultaneously enhancing optical performance. These coatings ensure that your infrared optics maintain their performance even in challenging conditions.
Omega Optical also provides a range of FT-IR accessory optics, including Attenuated Total Reflection (ATR) sampling optics and liquid cells.
In FT-IR spectroscopy, precise light guidance from source to sensor is crucial. Our off-axis parabolic mirrors are designed to direct light efficiently, minimizing loss and enhancing the quality of the spectral data. These mirrors are crafted with high precision to ensure that every photon is utilized, resulting in superior sensitivity and accuracy in your measurements.
Our proprietary infrared coatings are engineered to provide optimal protection for infrared optics while maintaining their performance. These coatings are specifically designed to seal hygroscopic crystals, such as KBr and CsI, against environmental factors. By preventing moisture ingress, our coatings extend the longevity and reliability of your FT-IR components.

Key components for FT-IR
Beamsplitters
The primary function of a beamsplitter is to separate a single beam of light into two parts, one reflected and one transmitted. The incident light is split at the surface which is usually set at some angle so the reflected and transmitted beams are separated. Any metal layer that forms a partially reflective mirror can serve as a beamsplitter, and many under the “plate” category are no more sophisticated than that.
Windows
Our windows and window coatings are designed to withstand environmental conditions such as temperature changes, humidity, abrasion, and mechanical stress, ensuring that the performance of the optical system remains unaffected. Optical windows can be made from various materials, such as glass, fused silica, or crystals, depending on the specific requirements of the application, such as the wavelength range and environmental durability needed.
ATR Prisms
Omega produces ATR (attenuated total reflection) prisms from a variety of materials and sizes.
Off-Axis Parabolas
Omega Optical produces diamond turned off-axis parabolas in a variety of configurations, as well as coated or uncoated. We are specialists in producing OAP's with excellent mechanical or optical datums to ensure easy, precise, and repeatable alignment.
