Introduction to the Traditional Polishing Process of Optical Lenses
During we polish the lenses, the lens may be tested to confirm that the desired shape is being produced, and to ensure that the final shape has the correct form to within the allowed precision. Precision lenses VY manufacture for use in applications such as lasers, interferometers, and holography have surfaces with a tenth of a wavelength (λ/10) tolerance or better.

General Parameters of Optical Lens
In order to understand optical specifications, it is important to first review what they mean. VY Optics provide a simple instroduction of optical specification here. To simplify the ever-growing number, consider the most common manufacturing, surface, and material specifications for lenses, mirrors, and windows. Filters, polarizers, prisms, beamsplitters, and fiber optics also share many of these optical specifications, so understanding the most common specifications will provide a great baseline for understanding nearly all optical lenses.

What Optical Designers Need To Know about High LIDT Optical Components' Manufacturing
With the continual development of optical technology, the demand for optical components capable of processing high-power laser beams has increased by double digits in recent years. This increase is primarily a response to the steady increase in power of continuous wave (CW) and pulsed solid-state fiber lasers and disk lasers.

The core material of a new type of reflective screen of tungsten trioxide
Tungsten trioxide is that the core material during a new sort of reflective screen — sometimes described as “electronic paper” — that gives optimal color display and uses ambient light to stay energy consumption to a minimum. The new technology might be utilized in displays for smart devices.

"Super polishing" process can minimize scattering
“Superpolishing” refers to processes that are designed to supply surfaces featuring an exceptionally low scattering of sunshine within the UV to IR wavelength ranges. These super-polished surfaces often demonstrate surface scattering levels less than 1ppm (wavelength dependent). In terms of surface roughness, this typically means surfaces with significantly but 1A RMS, integrated over spatial scales from approximately 1 micron to 100 microns. Super polished surfaces could also be flat or spherical with a radius of curvature as short as 20mm.

Free-form surfaces will bring more opportunities and challenges to the field of optics
Freely designable optical surface profiles offer lighter, simpler, and more compact assemblies versus their spherical counterparts, but they're tougher to manufacture and measure. The classic example of a freeform surface in ophthalmic applications is that the varifocal lens commonly utilized in eyeglasses. thanks to the traditional aging process, the eye’s ability to adapt between near and much slowly decreases. This results in discomfort, especially at close range. the good advantage of varifocal lenses is that they combine different strengths in one lens.

Innovative design of optical system
The design of high-end optical systems for a demanding application usually starts with the specification of the six main parameters: magnification, focal distance, resolution, depth of focus, spectral range, and target customer price.

Nd: YAG Laser - Really Stand the Test of Time
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, Nd, typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are of similar size. It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as red chromium ion in ruby lasers.
