In addition to the reflector, an ERS also includes a lens tube that can be swapped out to alter the focus and spread of the light beam. These lens tubes, also known as “barn doors,” contain a series of lenses that can be adjusted to zoom in or out on the beam, or to spread it out into a wider flood.

Ellipsoidal lights are also known for their high-quality light output. The light beam is typically very bright and has a smooth, even intensity, which makes it ideal for illuminating people and objects on stage. In addition, ellipsoidal lights are designed to be energy efficient and have a long lifespan, making them a cost-effective lighting option for stage and event production.

Ellipsoidal lights are known for their versatility and precision, as they can produce a variety of different beam shapes and sizes. The reflector and lens system of an ellipsoidal light allows the user to control the beam angle, focus, and intensity of the light, making it a useful tool for creating various lighting effects.

The history of ellipsoidal lights can be traced back to the early 20th century, when the first stage lighting instruments were developed. These early fixtures were relatively simple and were primarily used to provide basic illumination for the stage. Over time, however, lighting technology has advanced significantly, and modern ellipsoidal lights are much more sophisticated and capable than their predecessors. Today, ellipsoidal lights are an essential part of any stage lighting setup, and they are used by lighting designers around the world to create stunning visual effects.

Ellipsoidal lights come with a certain size lens or lenses that determines the field angle, range from five degrees to ninety degrees.

One of the main features of an ellipsoidal light is its adjustable shutters, which are blades or barn doors that can be positioned around the lens to shape the beam of light. These shutters can be used to create hard edges or feather the light, as well as to cut off light in certain areas of the stage.

The incorporation of this technology into the prescription lens eliminates the issue of having to wear two sets of glasses to both correct vision and use AR. It also streamlines the process of creating these glasses. Luxexcel has recently partnered with lens manufacturer Optiswiss, allowing faster production of glasses such as these.

Fixed lens – Most manufacturers now use field angle to indicate the fixture’s spread typically in this series (5°, 10°, 19°, 26°, 36°, 50°, 75°, 90°), among these, most widely used lens degree is 19°, 26°, 36°.

Whether it is used for creating and testing prototypes or for final production, 3D printing is a great indicator that R&D Credit eligible activities are taking place. Companies implementing this technology at any point should consider taking advantage of R&D Tax Credits.

It is named after the shape of the reflector that is used to focus the light beam. This reflector is an ellipsoid, which is a geometric shape that is similar to a sphere but is flattened at the poles. The light source is placed at one of the foci of the ellipsoid, and the reflector is used to focus the light beam onto a specific area or object.

In 2007, it was taken off of the NYSE when it was acquired by private equity firm Warburg Pincus and was sold again in 2013 to Valeant Pharmaceuticals. In May 2022, Valeant Pharmaceuticals (now Bausch Health), went public, putting Bausch & Lomb back on the NYSE. After reviewing Bausch & Lomb’s patent portfolio, it is unclear if and how often the company uses additive manufacturing in its work, but it is becoming a more standard practice to manufacture contact lenses using 3D printing.

There are three main components of a ellipsoidal light: the light source(lamp) which is in the back or called engine, the shutter blades in the barrel that shape the light, and the lens in the front.

A patent to produce optical lenses using 3D printing was issued in 2015 to Uwe M. Clasen, in which printing is used in conjunction with a laser to provide a custom prescription to patients in need of vision correction. Since then, this technology has come very far. 3D printing is now being used by Luxexcel to create an augmented reality-ready prescription lens.

Using their turnkey solution VisionPlatform, the company prints lenses with layers of acrylic-based resin with extreme precision, tailoring each lens specifically to different prescriptions. Between layers of resin, the printer may also embed smart devices into the lens, using waveguides and LCD screens to provide the user with the AR experience when used.

3D printing can help boost a company’s R&D Tax Credits. Wages for technical employees creating, testing and revising 3D printed prototypes can be included as a percentage of eligible time spent for the R&D Tax Credit. Similarly, when used as a method of improving a process, time spent integrating 3D printing hardware and software counts as an eligible activity. Lastly, when used for modeling and preproduction, the costs of filaments consumed during the development process may also be recovered.

Overall, ellipsoidal lights are an essential tool for lighting professionals in the entertainment industry. They offer a high level of control and versatility, along with excellent light quality and energy efficiency. Whether you are lighting a stage, a television set, or a live event, ellipsoidal lights can help you create the perfect look and mood for your production.

One of the main benefits of ellipsoidal lights is that they can be easily adjusted to achieve a variety of lighting effects. The beam can be shaped and focused using the interchangeable lenses and shutters, and the angle of the light can be adjusted using a system of mirrors. This makes ellipsoidal lights a versatile tool for lighting designers, who can use them to create a wide range of looks and moods on stage.

One of the largest optics companies in the world, Bausch & Lomb was founded in 1853 in Rochester, NY. It has made countless innovations in lenses and vision improvement throughout the 20th century and continues to develop new technologies, including the development of soft contact lenses as we know them today. The last 15 years have seen some changes in the governance of the company, however.

The ellipsoidal reflector of an ERS is responsible for shaping the light beam. It consists of a shallow elliptical dish that is coated with a highly reflective material, such as aluminum. When the light source (usually a halogen or discharge lamp) is positioned at one of the foci of the ellipse, the light is reflected off the dish and focused onto a small, defined area. By adjusting the position of the lamp within the reflector, the size and shape of the beam can be manipulated.
