Fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image.The focal lengths of fisheye lenses depend on the film format.Fisheye lenses achieve extremely wide angles of view by forgoing a rectilinear image, opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex...

Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters and unsurpassed surface quality. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be...

Specification of our beam-splitter as follow: Material:BK7 Grade Aoptical glass Dimension Tolerance: ±0.2mm Clear Aperture:>90% Flatness :λ/[email protected] Beam Deviation :<3 arc minutes Surface Quality: 60/40 Coating Partial reflectance on hypotenuse face AR coating on all entrances T/R ±5%, T=(Ts+Tp)/2,...

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices. Specification of our waveplate as follow: *Dimension Tolerance:+/-0.20mm to +0.01/-0.01mm...

Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary. Color Separation Filter,Neutral Density Filter,Filter,Short/Long Wave Pass Filter,Bandpass Filter and Interference Filter Specification of...
