Telephoto lens has a narrower angle of view, it thus gives apparent magnification to objects, it also seems to compress distant things, and there is less depth of field. The most obvious is to allow photographs of distant organisms to be made. Specification of our telephoto lens as follow: *25mm, 27mm, 28mm, 30mm, 30.5mm, 34mm, 37mm, 43mm, 46mm, 49mm, 52mm, 55mm, 58mm, 62mm, 72mm 2.0x telephoto lens; *37mm 2.5x and 3.0x telephoto lens; *52mm 3.0x telephoto lens;

Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And optical filters are widely used in scientific experiments and industrial applications where that change is necessary. China star optics can supply a full range of filters, color separation filter, neutral density filter, filter, short/long wave pass filter, bandpass filter and interference filter. Specification of our color filter as follow: material:filter glass, bk7 dimension: 4mm-160mm - 0.20mm squares/rectangles:1mm-165mm thickness:0.5mm-4mm wavelength range:190nm to 4.5um thickness tolerance:+/-0.01mm-0.1mm edges:fine ground flatness:up to lambda/10 surface quantity: 80/50-20/10 scratch/dig

Fisheye lens distorts straight lines into ridiculous curves. Straight lines, depending on where they are in the photo can be pulled a lot, a little, or not at all. The farther they are from the the center line of the photo, the more distortion there is. The closer the line is to the midpoint of the x or y axis of the lens, the straighter the line will be. specification of our fisheye lens as follow: *37mm 0.42x fisheye lens; *72mm, 82mm 0.7x fisheye lens

We are offering Glass Ball Lens, Jgs1 Ball Lens, Led Lighting Systems. Ball lens are highly transparent spheres made of optical glasses.They are used as fiber interconnects in telecom and expanded beam connectors. Large ball lenses have been successfully used as collectors in LED lighting systems and medical devices.They have high coupling efficiency and should be much easier to align than traditional lenses due to its physical shape.
