Resolution is defined as the ability of an optical system to differentiate between two closely spaced lines. In terms of the optics, the limit of resolution of a microscope objective refers to its ability to distinguish between two closely spaced Airy disks in the diffraction pattern. The Airy disk represents the absolute limit of resolution achievable by an optical system. (Ultimately, any image is made up of an astronomical number of Airy disks). According to the Rayleigh Criterion, the objects will be resolved when they have a separation of at least R.  In an ideal optical system, the optical resolution is restricted by the numerical aperture (NA) and by the wavelength of light;

The resulting image resolution is a measure of the degree to which the digital image represents the fine details of the analogue image recorded by a microscope.

Omega Optical is capable to provide patterned metallic coatings for vacuum applications where a window or filter needs to be soldered in place.

Diamond-like-carbon coatings are used across many industries in magnetic storage disks, car and engine parts, biomedical implants, and cutting and forming tools. They are a preferred choice in defense and security applications where environmental factors necessitate an anti-reflective coating with high durability and ability to withstand harsh conditions.

An anti-reflective coating (AR coating) enhances transmittance. AR coatings improve the efficiency of optical instruments, enhance contrast in imaging devices, and reduces scattered light that can interfere with the optical performance of telescopes, cameras, and binoculars, and decreases glare on eyeglasses.

There are two parameters which define the resolution of a digital image, ie. the amount of information that a digital image holds. Firstly, the spatial resolution, which is the number of pixels used to construct an image. Obviously, the more pixels that are present in a given amount of area, the higher the spatial resolution will be. But resolution is also dependent on the dynamic range available to the pixel elements. The dynamic range is the range of intensity values or grey values that the detector can differentiate. The pixels in a digital image will have discreet grey levels that cycle between varying levels from white to black. The cycle rate between black and white levels is called the spatial frequency. When the sampling frequency is reduced, fine details are lost, resulting in aliasing. The greater the dynamic range of a detector, the better the contrast will be. The contrast …..

Oleophobic & hydrophobic coating is a type of Broadband Anti Reflective (BBAR) coating that resists water, oil, smudges and fingerprints. It is ideal for windows and lenses which are exposed to high-touch or harsh environments. We can coat glass or plastic substrates up to 36″ diameter or 12″ x 30″ rectangular plates.

Resolution is proportional to the size of the NA and inversely proportional to the wavelength. Therefore, if the highest possible resolution is to be achieved, then either the probing frequency must be increased, or the size of the NA should be increased. Illumination with with ultraviolet light (UV), rather than photopic wavelengths, will permit finer detail, allowing the user to observe better resolution of the subject. However, by decreasing the illumination wavelength, finer and finer detail can be resolved, until a threshold limit is reached, called the diffraction limit. The ideal diffraction limit of an optical microscope is around 200 nm, around half the wavelength of illumination. However, this is an ideal measure which can never be achieved due to imperfections in the optics.

Coatings designed and manufactured using dielectric materials can be tailored to balance specific transmission, reflection, and beam splitting requirements in addition to durability requirements.

With 66 precision optical coating chambers, Omega Optical is capable to coat the equivalent area of eight regulation soccer fields (yes, 120 by 80 yards)!

Our ISO 9001:2015 certified facilities ensure the highest quality control standards through process discipline. USA-based manufacturing locations in New York, Massachusetts, New Hampshire, and Vermont enable us to serve our customers nimbly, shortening lead times and often allowing our customers to accelerate their time to market.

We can coat single optics up to 3 meters in diameter with high uniformity, OR gigantic batches of components. DUV to FarIR, millimeter to meter-class optics, NO ONE else provides such a broad capability and capacity.

Omega has the ability to coat large plates and dice down to sub-millimeter scale, or even coat onto individual ~150 micron optical fibers!

Metallic mirror coating allows you to choose the optimum spectral range of reflectivity and durability for both large and small components. Metallic mirror coating materials include aluminum, silver, rhodium, and gold. Protected and enhanced mirror coatings are available as well.
