How to care for and clean optical surfaces
نویسنده
چکیده
Many ophthalmic devices have optical components such as windows, lenses, mirrors, filters, and prisms; even very small irregularities (such as scratches) can cause unwanted scattering of light which reduces quality. The surfaces of lenses, prisms, and windows are often coated with an antireflective layer to prevent loss of light due to reflection. Mirrors have a highly reflecting coating to get maximum reflection of light. Filters have coatings to cut out undesired wavelengths. The coatings are very thin and delicate and can be damaged by improper handling and cleaning. By following these suggestions, you will help ensure that all of the optical surfaces in your eye care equipment perform optimally.

Study of Optical Models Regarding the Human Eye
Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...
متن کاملOptical Conductivity of Clean Metals
We briefly review some basic aspects of transport in clean metals focusing on the role of electron-electron interactions and neglecting the effects of impurities, phonons and interband transitions. Both for small Fermi surfaces of two and three-dimensional metals and open Fermi surfaces of quasi one-dimensional metals the dc conductivity σ is largely dominated by momentum and pseudo-momentum co...

Work function and surface energy per unit area were calculated in the framework of density functional theory (DFT) with Linearized A ug mented Plane Wave Plus Local Orbital method in full potential for a clean symmetric slab of silicon containing two (top and bottom) surfaces. The surfaces were theoretically modeled using supercell technique by stacking a variety of silicon layers along (111)...
متن کاملOne Pot Chemically Attachment of Amino Groups on Multi walled Carbon Nanotubes Surfaces
Functionalization of multiwalled carbon nanotubes (MWCNTs) with NH2 groups under a one pot reaction is studied. During the first step of the reaction, Cl and CHCl2 groups were attached to the surfaces of MWCNTs through an electrophilic addition reaction. In the second step of process, Cl atoms were replaced with NH2 and amino groups (ethylene diamine and but...
متن کاملSynthesis of CdTe quantum dots coated with biocompatible materials and investigation of their identification Properties
Fingerprint identification or dactyloscopy is a method for human identification. The impressions left by a human finger on surfaces are not visible to naked eyes (latent fingerprint); therefore, they require revelation to become visible and identified. Within the last century, several fingerprint revelation techniques such as optical, physical, and chemical were studied. These traditional metho...
