Candles on a cake, Schlieren image. The candle flames (white, lower centre) are heating air that is seen coiling (yellow, green and red) as it rises. Schlieren photography is used to visualize density changes in transparent materials. This change in density causes light passing through a material to change direction (refraction). This property is measured by the refractive index of a material. A filter is then used to colour the light depending

Optical activity. Image 2 of 2. Optical activity of fructose demonstrated by using polarized light. Optically active compounds rotate light waves that pass through them. This can only be seen under polarized light, light that vibrates in one direction only and is produced by using a polarizing filter. Polarized light passes through the fructose, and then through another polarizing filter. The second filter shows fructoses optical activity

Description

One of the most frustrating problems facing any digital photographer is the inability to fit an entire group of people or

breathtaking landscape scene in the picture. While you can't remove the standard Coolpix lens and replace it as you can on

an interchangeable lens SLR camera, you can quickly and easily attach this accessory wide-angle lens onto the camera's

built-in lens to get the results you want.

The Nikon WC-E63 converter increases the wide-angle view of your lens by a magnification of 0.63x to offer enhanced coverage

equivalent to that of a 24mm lens on a 35mm SLR. Both autofocus and auto-exposure functions are retained. In addition, it accepts 72mm filters thereby offering even more creative options.

Matching the optical design of this accessory lens to their camera's prime lens, resulted in Nikon's creating the highest

quality wide-angle lens attachment possible for the Nikon Coolpix 775, 995, 990, 950, 910, 900, 900s, 800, 880, 885, 4300 and 4500 cameras.

Please note that the WC-E63 directly attaches onto the 28mm filter threads of the Nikon Coolpix 4500, 995, 990, 950, 910, 900, 900s, and 800 cameras but requires the Nikon UR-E4 Adapter (not included) for the Nikon Coolpix 4300 and 885 cameras and requires the Nikon UR-E2 Adapter (not included) for the Nikon Coolpix 880 and requires the Nikon UR-E3 Adapter (not included) for Nikon Coolpix 775.

Features

• 4 lens elements in 4 groups
• 24mm equivalent lens (0.63x magnification)
• For use with Nikon CoolPix digital cameras
• Requires UR-E3 adapter ring to work with Coolpix 775/UR-E4 adapter ring to work with Coolpix 885
• Not for use with Coolpix 2500
