Typically fisheye lens has a front lens group of a greater negative refractive power than an ordinary inverted telephoto wide angle lens, with a large back focal distance. Its extreme power distribution will cause great field curvature in the transmitted image. As fisheye lens leads to significant barrel shaped distortion, to improve field curvature and astigmatism, it is necessary to compose a doublet to avoid significant negative deviation and provide correction of chromatic aberration.

Hyperion Optics designers’ expertise contributes various range of fisheye lenses customized projects, from sminiature fisheye lense used for 360 degree viewing device to 200mm in diameter dome projection fisheye lenses. Our fisheye lens database provides design result and simulations for full frame fisheye lenses, circular image (hemispherical) fisheye lenses with different focal length options.

During design process, our designers evaluate relative illumination performance by utilizing real ray trace analysis, vignetting is also used to control off-axis aberrations due to a half stop or full stop in relative illumination is tolerable in conventional photography scenario. Distortion departure from f-theta mapping is also critical in our design phase, according to the initial simulation and calculation; our designers are able to adjust and optimize to reach an ideal solution. We also look into lateral color which is the lateral shift on the image plane intersection between the shortest wavelength chief ray and the longest wavelength chief ray by real ray trace analysis.

Asphere Lenses

Due to the more complex surface profile of asphere which significantly reduces or eliminate optical aberrations as compared to the simple lens, Aspheric lenses have at least one surface that is not a true sphere,It has been more widely exploited in the lens optical design stage.

IR Asphere Lenses

At Hyperion Optics, we work with various infrared materials. Besides spherical parts, with increasing demand of IR aspheric components, designers are more likely to use aspheric parts in LIRP projects to meet relatively reliable performance meanwhile to decrease the element quantity within the system. Our aspheric component manufacturing capability covers 0.8 micron up to 12 micron for your infrared application from combination of materials needed in order to achieve your application expectation.

Diffractive Optical Elements

Diffractive optical elements (DOEs) shape and split laser beams in an energy-efficient manner. You can implement a broad range of applications with minimal light loss – examples of diffractive micro optics can be found in production facilities for laser material processing, in medical laser treatments and diagnostic instruments, in areas such as lighting, printing technologies, and lithography as well as in measuring and metrology systems. DOEs are used to pattern light in work areas for custom illumination. Hyperion Optics offers DOEs for all wavelengths across the spectrum.

Parabolic Mirrors

Parabolic reflectors are used to collect energy from a distant source (for example sound waves or incoming star light). Since the principles of reflection are reversible, parabolic reflectors can also be used to focus radiation from an isotropic source into a narrow beam. In optics, parabolic mirrors are used to gather light in reflecting telescopes and solar furnaces, and project a beam of light in flashlights, searchlights, stage spotlights, and car headlights. In radio, parabolic antennas are used to radiate a narrow beam of radio waves for point-to-point communications in satellite dishes and microwave relay stations, and to locate aircraft, ships, and vehicles in radar sets. In acoustics, parabolic microphones are used to record faraway sounds such as bird calls, in sports reporting, and to eavesdrop on private conversations in espionage and law enforcement.

Chalcogenide Lenses

Chalcogenide glass is containing one or more chalcogens (sulfur, selenium and tellurium, but excluding oxygen). Chalcogenide components are becoming popular in various IR applications due to its excellent wide band transmittance (3-5µm, 8-12µm) with reliable machinability, which perform rather differently from oxides; particularly low band gaps help optical designers to introduce more flexible IR solutions.

Zinc Sulfide Lenses

Pieces Knowledge: Basic Knowledge of Optical Lens Grinding Process

I. The grinding purpose and fundamental principle

1. Purpose:
(1) to remove the damaged layer of fine grinding to meet the requirements of the specified appearance limit
(2) To finish the surface, let curvature radius R circular reaches a specified value, meet the requirements of the number of NR and the local curvature of the aperture tolerance (Yasi).
2. Fundamental principle
By mechanical movement, the mechanical action will occur between the grinding agent and the glass in the grinding dish. And the purpose of precision polishing will achieve.

II. the types and use of the required dish

1 grinding dish: used for grinding lens
2 fixture: used to hold the optical lenses for fine grinding
3: relay equipment: the joint between machine and grinding dish, the height and coaxiality is adjustable.
4 dishes: used to repair the accuracy of the drill plate
5 drilling dish: it is used to correct the precision of grinding plate (drilling dish is by diamond particles curvature surface sticking into or out of shape curvature surface, its accuracy is generally +2 dish, dish 0~-1 negative, it is used for repairing and grinding the skin)

III. The main control point for grinding

1. Check the fixed points, scars, sand, broken, frog skin, corrosion on the surface or not.
2. Check the quantity of Yasi, vertical edge, the number of the surface is under the limit or not.
3. Check the grind quantity is in the within standard or not.

• The Yasi ---- surface precision deviation image circle of confusion  (ellipse, saddle-shaped, pillar), local irregular aperture (middle part high, middle part low, vertical edge)
• Middle part high---When the lens and the original contract fully, a small aperture will be thick, when we pull the edge,  the center will hump inward, pull 1/2, an ellipse will occur.
• Middle part low - when the lens and the original contract fully, the center of the aperture gap is too narrow, too dense. When we pull the edge, the central bulge outward, pull 1/2, the ellipse will appear.
• Corrosion, usually referred to as corrosion, is the appearance of a massive, punctate, fog like phenomenon caused by the chemical reaction between the surface of optical lenses and water or other substances in the air.
