Spherical lenses  are lenses taken out from a sphere such as a ball. Where as, cylindrical lenses are lenses taken out from a surface of a cylinder like a tumbler. Cylindrical lenses have an axis associated with them. Both, spherical and cylindrical power can keep changing through life.   What Does A Cylindrical Lens Do? A cylindrical lens is typically used to focus, condense or...

  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 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.   Anamorphic Prism   Description   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.   For more information about custom optical c...

  Neutral optical density filter   is often used in imaging or laser applications to avoid strong light damage to camera sensors or other optical components. This kind of optical density filters absorb or reflect untransmitted light to evenly reduce transmission in a given part of the spectrum.   Ecoptik (also known as BRD Optical) provides different types of neutral optical density filter wholesale. If you want to get the neutral density lens filters   price, please feel free to contact us.   Description Of Neutral Optical Density Filter     Ecoptik makes fixed OD value neutral density filter by depositing Inconel film on a clear cubstrate. The advantage of the optical density filter is in the broader band and lower ripple than that of absorptive density filter. The coated wavelengthcan be extended to 200nm to 1100nm or more. The disadvantage is that there is some reflective light on the optical filter glass. The OD value can vary from 0.1 to 0.5. The...

  Ecoptik (also known as BRD Optical) 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 Meniscus Lens Ecoptik (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 lens 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 r...

  Fused silica glass has a high transmittance from ultraviolet to near-infrared (185nm-00nm), and has a high transmittance in the deep ultraviolet region, making it widely used in ultraviolet lasers. In addition, compared with ordinary optical glass, fused quartz glass has better uniformity and lower thermal expansion coefficient, making it particularly suitable for applications in the ultraviolet to near-infrared wavelength range, high-power lasers and imaging fields. Ecoptik can provide the best fused silica, if you want to know the fused silica price, please feel free to contact us.   Fused Silica Descriptions As a major optical product material, the main characteristics of fused silica are:   High purity and corrosion resistance   High softening temperature, strong heat resistance   Low thermal expansion coefficient, thermal shock resistance   From the ultraviolet band to the infrared band have good light transmission performance   Strong radiation...
