Double Convex Lens

图片
 The double convex lens /mirror is symmetrical across both its horizontal and vertical axis. Each of the lens's two faces can be thought of as originally being part of a sphere. The fact that a double convex lens /mirror is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its principal axis. A  double convex lens/mirror is a converging lens. A double convex lenses/mirror is also symmetrical across both its horizontal and vertical axis. The two faces of a double concave lens can be thought of as originally being part of a sphere. The fact that a double convex lens is thinner across its middle is an indicator that it will diverge rays of light that travel parallel to its principal axis. A double concave lens/convex lens mirror is a diverging lens. These two types of lenses - a double convex and a double concave lens/mirror will be the only types of lenses that will be discussed in this unit of The Physics Classroom Tutorial. I...

Anamorphic Prism

图片
  An anamorphic prism pair is a pair of prisms which is usually used for reshaping the profile of a laser beam. For example, the elliptical beam from a laser diode can be transformed into a beam with circular cross-section, as is needed for many  applications, by using an optical prism pair  as a prism beam expander  for only one direction (e.g., the horizontal one). Of course, one can also just modify the ellipticity, or convert a circular beam into an elliptical one.   Descriptions of Anamorphic Prism Diode lasers usually have elliptical beam profiles. In most cases, though, the shape of the circular beam is required, such as pattern matching with the external resonator to make the beam size adapt to the small aperture through the isolator. A deformed pair of anamorphic prisms is used to transform an elliptical laser diode beam into an approximately circular beam to amplify an elliptical beam in one dimension.   We can also provide kinds of precision opti...

Optical Dome

图片
 The optical glass dome  is our company's superior product. In the past, most of the fairings were infrared grade, which was mostly used in military products.   With the development of military-civilian integration, especially in visible materials and ultraviolet, we have become one of the best optical components companies and have made technological breakthroughs, and we have obtained the patent certification of ultra-hemispheric processing technology. The optical domes  are widely used in camera dome imaging, weather monitoring, navigation systems and  so on. The radii of curvature of the two planes will not cause image distortion and light refraction. Ecoptik can provide different kinds of optical dome, like a clear dome, UV dome and IR dome. Optical Dome Applications In the optical field, the application of an optical dome lens is mainly divided into two categories, one is military manufacturing and the other is ordinary optical systems. Military manufacturi...

Meniscus Lens

图片
 Ecoptik China provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations.   Description Of Positive & negative lens Ecoptik  China (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens. Positive Meniscus Lens A positive meniscus lenses  consists of two curved surfaces with similar radii of curvature and has a positive focal length. Positive meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce spherical aberratio...

Witness Samples

图片
W hat are witness samples Coating on different optical surfaces, including spherical, aspherical, planar, etc., but how to better detect the performance of thin film? The usual landscape photometer detection systems are suitable for plane detection, from which the witness samples are derived. Through the witness sample, the transmittance, reflectivity, actual applicable temperature, moderate and so on of the film can be detected.   DESCRIPTIONS   Descriptions of Witness Samples The witness samples provided by Ecoptik China include a full range of brands such as CDGM, Schott, CORNING, etc. The general diameter is about 1'' and the thickness is 1-3mm, which basically adapts to the size of standard spectrophotometer tools.   Ecoptik China witness samples be polished one side or both surface according to the customers' requirement to be used meet for transmit or reflect thin film coating.   SPECIFICATIONS   Specifications of Witness Samples There are many optical co...
