  Based on the technique of all-dielectric hard coating and the principle of dielectric interference, and based on the characteristics of narrow-band optical pass filters, the optical properties are independent of the substrate. The narrow band bandpass filter  produced by Ecoptik (also known as BRD Optical) is more convenient to be built into the instrument imaging system so that its optical performance can be improved and effectively applied. The special optical material substrate is used to solve the problem that the absorption type synthetic glass is easy to mold and the optical performance is unstable. The narrow-band optical pass filters are produced according to the customer's index requirements.   Description Of Narrow Band O ptical Filter   Bandwidth refers to the distance between two positions in the passband whose transmittance is half of the peak transmittanceThe above six parameters must be taken into account in the use and selection of narrow-band filters. Different p

  Ecoptik (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. These china concave meniscus lens  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 meniscus  lengths. On the aspect of shape, it can be divided into convex and concave meniscus  lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens .   As one of the   optical components companies , we provide custom optical components , dome flange , diverging meniscus lens, custom optical lenses  and etc. Want to know   uses of positive meniscus lens   or what is positive meniscus lens ? Please contact us.

  Meniscus Cylind er  Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.   Description Of Meniscus Cylindrical Lens   It is a lens that one surface is the convex shape, another surface is concave with a cylindrical shape, its role is making beam converging or diverging on a plane, and that beam doesn’t work for the perpendicular plane(cylindrical axis) with it. A cylindrical lens is used in turning a transmitted plane wave into a cylindrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation.   Ecoptik (also known as BRD Optical) uses classical processing technology and strict process control to ensure that the surface accuracy of the

  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 resistance   Fused Silica Specifi
