What Is An Optical Beam Expander?
An optical beam expander (also known as a collimator or up-collimator) is a two, or more, element optical system that changes the divergence characteristics and the size of the beam.  They take a beam of light and expand its size. They are also used to reduce the beam diameter which may be useful when using acousto- […]
High-Resolution Lens Assemblies
UKA specializes in designing and manufacturing high quality, precision lenses. We have several high-resolution lens assemblies from which you can choose depending on the specific parameters that would be the most suitable to meet the requirements with respect to image size and quality.
Laser Technology Advancements
Imagine knowing enough about Earth’s atmosphere to predict climate trends, or knowing enough about a hurricane to get the right people evacuated. Consider a time when advances in medical procedures retire the scalpel to the museum. Even in precision-manufacturing, laser technology advancements can potentially bring consumer costs down because of its efficiency.
How Lenses Are Designed
Lenses can be found in objects that range from microscopes, lasers and other pieces of medical equipment, in the automobile industry for sensors and in self-driving vehicles and for security equipment. What is optical design? The business of lens design and manufacture is based on specifications of a particular client or object into which the […]
Thin Lens Captures Colors
Researchers from the Harvard School of Engineering and Applied Sciences have developed a flat, ultra thin lens that is made from light-concentrating silicon antennas and a glass substrate. This lens is capable of color correction at a high level in a single, miniaturized lens. Shining light through an “achromatic metasurface” means the lens will automatically […]
How To Choose A Lens Manufacturer
Choosing the correct lens manufacturer is crucial to your company receiving the lens necessary for the tasks it performs. Whether you’re in the medical, optical or any field in between that utilizes lenses, take your time to assure you’re getting the best manufacturer for your unique lens needs. When you’re in the market for a […]
What Is Polarization?
Optical applications, in many instances, require an understanding of the manipulation of polarization of light. In optical design, many times the focus is on intensity of light and wavelengths while at the same time ignoring polarization. This isn’t to say that polarization isn’t a crucial part of the process, but polarization in and of itself […]
Optical Design And Optical System Integration
The optic lens manufacturers from UKA Optics field the question several times, “What is optical design?” They also work with potential customers and explain how optical design connects with all other optics areas, optical engineering and optical systems. If you’re a “general reader” interested in general information about lenses and optics then this post is […]
The Art Of Creating Custom Lenses
The manufacture of lenses is a precise art and UKA Optics creates custom lenses that encompass all measurements and testing applications for many industries, medical, scientific, and military applications and more. As background to the exacting science of measurements you need to understand how an inch became an inch and why a pound is not […]
What Is A Band Pass Filter?
Bottom line, a band pass filter is “an electronic circuit or device that allows signals to pass between two frequencies.” This device will be able to discriminate and separate signals of different frequencies other than those specified. Certain band pass filters will require an external source of power and it will also use other active […]
What Are Optics and Photonics?
The lens manufacturing specialists from UKA Optics know that not everyone understands the role that optics and photonics play in everyday life and in medical and technical settings. It is their job to understand and to keep up with the latest technologies and changes in the optics landscape. What are photonics and optics? Fiber optics […]
Caring For And Cleaning Your Optics
The purchase of optics for your business or laboratory is an investment you will want to care for so that it provides a long life and a return on your investment. Cleaning and proper care will help not only maintain the quality of the optic device and its lenses, but it could extend its useable […]
The Benefits Of Hard Coating For Lenses
Traditionally, lenses and optical components were coated in soft coating. This is a process that might become obsolete because of the development of a high performing technique known as hard coating. This coating provides myriad advantages over traditional soft coatings. As background, soft coatings are multiple layer films that are used over optical components. The […]
What Are The Benefits Of A Custom Bandpass Filter?
UKA Optics, who designs and manufactures optical lenses for industrial, medical, high tech and electronic applications, explains that bandpass filters are “optical filters that allow for the transmission of specific range of wavelengths or band.” This type filter also blocks other wavelengths. There are off the shelf options for organizations that want to purchase bandpass […]
Uses For Optical Filters
An optical filter is used to “attenuate or enhance an image.” An optical filter can also reflect unique wavelengths, split images into two identical images or transmit an image. The importance of choosing the correct optical filter for the job you have at hand is crucial because its application will determine the style and fabrication […]
Thermal Imaging Moving Into The Personal Use Realm
The use of thermal imaging is not a new technology. It’s used by law enforcement when searching for runaways or others who may be lost. The thermal imaging can show a heat profile and helps the officers locate the individual. Thermal imaging is also used by home inspectors to check a home for heat leaks […]
What Is A Fresnel Lens?
Most typically utilized in light-gathering applications, a Fresnel lens is a compact lens originally developed by French physicist Augustin-Jean Fresnel for lighthouses. These lenses are lightweight and available in myriad sizes, provide ideal light gathering capabilities and are made of plastic. You most typically find a Fresnel lens in condenser systems or detector/emitter operations. Fresnel […]
What Are The Advantages Of Fresnel Lenses?
A Fresnel lens is typically used in “light gathering” applications including condenser systems, light emitter, detector setups, magnifiers and in projection lens or illumination systems. The Fresnel lens is comprises of a “series of concentric grooves etched into plastic.” The lightweight and thin construction of these lenses make them ideal for use in myriad applications. […]
Optical Coatings Improve Lens Performance
Precision optical elements, in many segments of today’s optics industry, include adding coatings to the lenses as a way to enhance their transmission or reflection of wavelengths. Anti-reflective (mirror), beam splitter and filter are the most common types of coatings that are applied to lenses for use in different technologies. Many industries currently rely on […]
Benefits of Meniscus Lenses In Infrared Technologies
A meniscus lens is not a usual off-the-shelf purchase as they have a specialized use in small spot size focusing and collimation. These lenses provide greater performance specifications at a minimal price increase over typical lenses. Because of the spherical nature of lenses it means that parallel rays, especially those from various distances, do not […]
The Benefits of AR Coating On Lenses
This application of anti-reflection (AR) coatings to lenses can improve the efficiency of the optics through increasing its transmission, enhancing contrast and eliminating any “ghost” images that may appear. The application of an AR coating will make the lens more durable and allow it withstand environmental and physical damage. This is a plus when the […]
